CP-1066 - discussion The CP passed Letter Ballot with Siemens voting negatively. After discussion by the WG-06 the CP was approved as final text with Siemens maintaining its objection. The discussion included the following points:
DICOM included a 16bit length field for data elements in explicit syntax many years ago. The length field is not large enough for all data types. The possibility to send studies with implicit syntax is always possible as there is no length field in this syntax, but implicit syntax has some limitations. However, this has not impacted patient safety adversely.
After these many years Guenther Zeilinger found a clever solution to the CP-1066 which has been unsolved for a long time.
This has been widely implemented by the radiation therapy industry in its “1st Generation” of standard.
Siemens argued that to prevent further loophole use when the standard uses data types which don’t work with the 16bit length field. Siemens proposed either a restrictions to cover legacy cases but closing the loophole for non-legacy or to add strong advice in the standard text to guide against misuse.
The balance of the members of WG-06 argued that the Siemens constraints would invalidate a very large installed RT base and further that the CP is not presenting a patient safety issue. It was noted that the objection is theoretical if all vendors follows the intention of writing CPs when better data types are needed instead of using unsuitable data types with overflow in the field size . The fact that it may be untidy is outweighed by the practical benefits 1696
_____________________________ Working Group Six (Base Standard) of the DICOM Standards Committee CP’s Sept. 14-19, 2015
inasmuch as the CP will solve real problems. The CP rationale has been updated to make the intention of the change very clear. Lastly that the impact of CP-1066 is on the creation side and not on the receiving side. 4. VP-Current (Voting Package) for September 2015) The CPs listed below have either been approved for the September VP at the June 2015 meeting or have been proposed for this Voting Package, following the June 2015 meeting. The CPs were reviewed and discussed at the Sept. 9, 2015 t-con of this Group, in preparation for this meeting. Seven CPs were deferred in the t-con for discussion at this F2F meeting, the others were recommended by the participants of the Sept. 9 t-con to be approved for inclusion in the next CPack-83 Letter Ballot. The decisions of WG-06, taken at this meeting, are shown below: the CPs were either approved by unanimous vote for inclusion in the next Letter Ballot (CPack 83) or were directed for further work (remained “Assigned”).

See CPXXXX_v1_ rfc3240_2015-0912.docx in the Sept 2015 WG-06 mtg folder/CP/New JAN 12 2015: Confirmed task SEPT 2015 – NEW: David Clunie will work with Marc to finalize CP and submission to IETF. Secretary will submit to IETF. 2015-SEPT mtg: discussed on Tuesday: Remains AS unless Uli finishes work on Friday. Friday discussion: missing in the CP the description of context without which difficult to interpret the se concepts.. How are the codes related to UPS task. Who would use the KOS Object? Which part of the workflow is managed by UPS or KOS? Need a description. Discussed specifically NNN7: both input and output are included. Getting loosey-goosey workflow into the Standard. DICOM does not use KOS for workflow. If IHE creates a detailed description of the workflow, DICOM would create the Codes. DICOM Code definitions should not include ‘workflow’.

Sept 2015: NEW Extensive discussion of Ref’d Image Sequence (RIS) and Source Image Sequence (SOS). It was suggested to write a macro for RT use cases and not mess up RIS and SIS. WG07 wants to record/annotate how segmentation was done More discussion needed at next meeting How is this related to the Common Instance Reference Module, and how does it handle references from within functional group macros?

Secretary will submit to IETF. 2015-SEPT mtg: discussed on Tuesday: Remains AS unless Uli finishes work on Friday. Friday discussion: missing in the CP the description of context without which difficult to interpret the se concepts.. How are the codes related to UPS task. Who would use the KOS Object? Which part of the workflow is managed by UPS or KOS? Need a description. Discussed specifically NNN7: both input and output are included. Getting loosey-goosey workflow into the Standard. DICOM does not use KOS for workflow. If IHE creates a detailed description of the workflow, DICOM would create the Codes. DICOM Code definitions should not include ‘workflow’.
Rem ains AS
2015-June mtg: Version 06 Adding a lot of Codes but decided this is not something for LOINC. Needs to remove term ‘series’, call it diagnostic images only. The terms should not duplicate themselves. Avoid “workflow” use “grouping RT objects” instead.

13. Supplement 121 – Modality Procedure Plan and Protocol Storage (CT) {WI-2006-04-E} This was a continued presentation for Letter Ballot. Editor K. O’Donnell presented the draft supplement posted prior to this session as . WG-06 continued line-by-line review for Letter Ballot for 6 hours over Monday, Wednesday and Thursday. In addition, on Wednesday, WG-21 discussed the Supplement in a separate meeting. D. Cody of AAPM, R. Ruf of Siemens, S. Gotman of Philips, and Brad Gilberts of GE assisted and supported the presentation. WG-06 directed various revisions. K. O’Donnell annotated and revised the document accordingly. The annotated document was posted in the meeting folder as Substantive changes included:
Revision of the Real World Diagram
Clarification/revision of the Attributes for Modifiable Constraint Flag, Content Qualification, Indications, Constraint Policy, Clinical Trial Name/UID, Model Accessories, CTDIvol, Noise Target
Generalization of the Hanging Protocol Selector Attribute Value Macro to the Attribute Value Macro
Expansion of Acquisition Element Description to address summary and purpose separately and clarify that this is not for instructions to the tech.
The line-by-line review was not completed due to lack of time. The supplement will return in November to complete line-by-line review for Letter Ballot.

14. Supplement 147 – 2nd Generation Radiotherapy Prescription [WI This was a post PC reading for Trial Implementation. U. Busch reported on the Public Comments. The comment period started in February 2015 and closed in June 2015. Several targeted outreach was made including special announcement in the AAPM Newsletter. Over 200 public comments were received. WG-07 reviewed and considered all comments and distilled and consolidated them to about 50 comments that resulted in revisions to the draft Standard. He will be reviewing the revised draft at this WG-06 meeting. U. Busch next presented the WG-07 plan to develop a Draft for Trial Implementation and request WG06 approval, after the review of the public comments. He also noted that experimenting by individual companies for trial implementation has already started, indicating the extent of thoroughness with which this industry is proceeding. In general, in trial implementation, standard tags can be issued and used or private tags may be used. In this case hundreds of tags are involved. In this case WG-07 intends to use private tags. (Ultrasound also used private tags.) Further, it should be clear whether trial implementation includes treatment of patients. In this case no patient treatment will be conducted. Chief technical issues discussed included:
Series in DICOM are collections of similar things, not of different things. For the latter a different construct should be used. WG-06 suggested to develop a definition of RT Study which may solve the series – related discussion.
Labeling Macros should be generalized to make them available for general use (Esp. 'RT' prefix should be removed)
The syntax used in the expression to combine Conceptual Volumes should be defined more strictly. R. Horn will provide some Links to possibly suitable specifications.
The supplement will return in November for continued reading of the PC phase comments and in January again for approval of the Trial Implementation draft. 15. Supplement 156 – Planar MPR Volumetric Presentation State {WI 2008-04-C} This was a continued reading for Final Text. WG-06 held several phone conferences, since the last WG-06 meeting, and completed the line-by-line reading and approved the Final Text. At the meeting of WG-11, last week, a few editorial changes were made. WG-11 made it clear that they can submit these last changes as CP’s if it would delay FT approval. However, WG-06 decided to review the few editorial; changes and allow inclusion in the FT. Thereafter the FT was approved unanimously; WG-06 congratulated Joe Luszcz on the completion, who in turn thanked Andreas Klingler and Jonathan Whitby for their significant contributions. The supplement was approved as Final Text. 1729

16. Supplement 174, RS (RESTFUL) (RETRIEVE) RENDERING – WI-2008-04-B) This was a reading for Final Text. The reading started in Q4 on Monday, in place of the scheduled Sup 183 discussion because Sup 174 is a major part Sup 183. The supplement passed Letter Ballot, on Aug. 18, 2015. Editor J. Philbin presented the draft that included the comments that were received during the Letter Ballot process. The document he presented was posted in the meeting folder as < sup174_v7_pre_final_2015-09-13.docx>. A lengthy discussion took place and all members of WG-06 contributed reviews and comments. The review of Sup 174 consumed the allotted time plus the time scheduled for Sup 183. If no additional time becomes available during the week to finish the Final Text. T-con(s) of WG-06 will be scheduled to complete the FT review and approval. The Supplement will return to complete Final Text if not approved FT in special t-cons prior to the next WG-06 meeting.
17. Supplement 175 –2nd Generation Radiotherapy - C-Arm Radiations {WI 2007-06-B} WG-07 decided to conduct a reading of RT Supplement 147 instead of Sup 175. 18. Supplement 176 –2nd Generation Radiotherapy – Additional RT Treatment modalities. {WI 2007-06-B} WG WG-07 decided to conduct reading of RT Sup 147 instead of Sup 176 during this allotted time.

19. Supplement 181 – Tractography Results Storage SOP Class {WI 2014-08-A} The title was changed from MR Tractography Storage SOP Class. This was a reading for Final Text; it started in the second half of Q1, on Tuesday. Jim Reuss represented, via web meeting, the Editor of this Supplement, Sven Flossmann, who could not be present today. Jim thanked the commenters for the thorough review. DTI Group members David Flade, Sonja Pujol, Elmar Seeberger, and Rowena Vigh were also connected by web meeting. Jim presented the GE comment and the DTI Group’s evaluation thereof that was posted as . Accepted most comments, detailed reasoning in the referenced document for not accepting certain comments. In the discussion of coordinating Value Pairs Sequence the question was posed whether OL should be added? If not, OB should be explained as to how to interpret it. WG-06 will consider this question, D. Clunie will draft a description of OL and will return to the point on Friday. With respect to the acronym comment it was decided that there is no obligation to describe term of art in a DICOM Standard. Next the Siemens Comments and the DTI Group’s evaluation thereof was discussed as posted in the file .Again, most comments were accepted. Explanation is shown for non-acceptance. D. Flade suggested another change for data retrieval, not yet in the Supplement; WG-06 concurred and asked to include the change in the current FT rather than introduce is as a CP. Finally the Hologic comments and the DTI Group’s evaluation thereof were reviewed as recorded in the document posted as . The WG-06 next proceeded to a line-by-line review of Sup 181 for Final Text (FT) on a copy that included tracked changes from the Letter Ballot Draft posted as . During this reading
Restored the General Results Series module and kept Tractography Series Module as well, throughout the draft.
Add attribute for a new IOD in Tractography Series Module
Noted that a potential new OL VR attribute may be added on Friday
Revised C.8.X.2.1
C.8.X.2.1.1 will be folded into the table.
The Tuesday review ended at this point. The line-by-line review will be continued on Friday.
After the Tuesday reading, the DTI Group (D. Flade) revised the Supplement 181 with the feedback given in the Tuesday session and the amendments from Jim and David Clunie that they 1731

have provided following the Tuesday reading. D. Flade prepared a document containing only changes related to feedback given up to that point. The changes have been:
Notes from Jim that he made to the supplement during the presentation.
Added new VR=OL (32-bit unsigned integer) for the attribute Track Point Index List (gggg,ee29) and the related amendment to the DICOM Standard as proposed by David Clunie.
Added some more attributes to the Tractography Results Series module as proposed by David Clunie.
Added a passage at the end of “C.8.X.2.1 Tractography Results Module Attributes” which was not part of the presented text yesterday. The added text is actually old text that was removed because it was thought to be outdated; however, after review by the chairman it was re-added. Unfortunately, the re-added passage did not make it to the supplement Jim presented yesterday. So, now it’s back in.
The revised document to be presented Friday morning Q1 Session was posted in the WG-06 meeting folder as document < sup181_lb_08_MR_Diffusion_Tractography_Storage.docx>. The post discussion document was posted as
The Supplement was approved as Final Text.
20. Supplement 183, Part 18 (Chapter 10) Re-documentation [WI-2008-04-B] This was going to be a First Read. However, the line-by-line reading of Sup 174 consumed the Sup 183 time as well. There was no discussion of Sup 183. The Supplement will return.
21. Supplement 184 – Brachytherapy Delivery Instructions {WI 2000-11-B} This was a reading for Letter Ballot. Editor U. Busch presented the document , which was posted in the Pub-Cmts folder, which also contained Sup184_PC_Comments-Philips-Medema.docx. These were the only comments received during the Public Comment period. Besides two small grammatical correction there was one question about scope etc, which U. Busch clarified with the reviewer prior to the meeting. A Plan IE definition was added and the Enhanced General Equipment C.7.5.2 included in the IOD. After line-by-line review the Supplement was approved for Letter Ballot. 1732 _____________________________ Working Group Six (Base Standard) of the DICOM Standards Committee CP’s Sept. 14-19, 2015
22. Supplement 185, Content Assessment (changed from ‘Object Evaluation’) Results IOD {WI 2000-11-B} This was a continued reading for Public Comment. The updates and insertions discussed at the last WG-06 meeting were completed prior to this meeting. U. Busch presented < Sup185_PCpre.doc>. An IE definition for Content Assessment IE was added and references to Supplement 121 have been updated. The supplement was approved for Public Comment. 23. Supplement 187 – Preclinical Small Animal Imaging Acquisition {WI- 2015-05-A} This was a reading for Letter Ballot. D. Clunie presented the posted document < sup187_13_preclinicalanimalacquisitioncontext.pdf>. There were no public comments. WG-30 has resolved the open and closed issues, completed the to do lists. The document presented was a proposed text for Letter Ballot. On Monday the Group started a line-byline review and discussed the draft extensively including directing several changes. Approximately 75% of the document has been reviewed during the Monday session. At the end of the session the changes were made resulting in < sup187_14_preclinicalanimalacquisitioncontext.pdf>, which was posted. The changes from v13 to v14 are shown in that was also posted in the meeting folder. The line-by-line continued and was completed on Tuesday. The Supplement was approved for Letter Ballot. 24. Supplement 188 – Multi-Energy CT Storage [WI-2013-08-A] This was a first read. Editor Reinhard Ruf presented; WG-21 members Dianna Cody, Brad Gabrielse, S. Gotman, and Kevin O’Donnell were assisting. The starting presentation is posted as < Sup-Multi-Energy-Images-2015-09-17-before review-withwg06.docx.> The discussion identified items needing further technical discussion: Standardized Color Maps 1733

Material Classification (Labeling) Images – use segmentation IOD instead of Image IOD Generate a new Sequence for ME KVP Attribute for supporting of spiral, non-spiral CT Additional X-Ray Source Sequence Mode proportion, move to macro Focal spots Exposure time, spiral, non-spiral Spiral Pitch Factor Retire Energy Weighing Factor? Multi energy in text and keywords Defined terms for Multi Energy CT Images Multi source with switching not covered
The post review draft is posted as < Sup-Multi-Energy-Images-2015-09-17-after review-withwg06.docx> The presenters noted that they intend to return for a reading for public comment, in January 2016. The Supplement will return. 25. Supplement 189 - Functional MRI Blending Presentation State Storage [WI-2014-12-A] This was a First Reading. W. Corbijn, Chair of the fMRI Group of WG-16, described the concepts of this supplement with the help of a power point presentation. Members of the WG-16 fMRI Group, Jim Reuss of Prism Clinical Imaging and Cathy Elsinger of Nordic Neuro Lab have assisted the presentation and participated in the discussion. The presentation was posted in the meeting folder as ppt file: . There was an extended discussion of the concepts and the open questions. The following conclusions were reached regarding the topics discussed: should target a full 3D support from data point of view without really going for the Volume Rendering already when the full version is completed one can see if it can be restricted to create a simple version that doesn’t need registration / MPR for creating one geometry space contour generation is a complex operation; consider to leave it to the application to implement this feature without describing in the Blending object. This way get a better adoption of the object. 1734
_____________________________ Working Group Six (Base Standard) of the DICOM Standards Committee CP’s Sept. 14-19, 2015
Alignment with the MPR supplement(s) is needed to get better take up of the supplement Threshold must be part of the Blending object and not from the parametric map. For this come up with the actually used types of ranges (LE, LT, GT and GE) and leave out extra capabilities that are not considered relevant in the near future. Use the Floating storage for the values if they are not integer by nature. Create function to map the values to a color range directly without using a color LUT and integer value range as intermediate step. Real world value mapping shall be used for communicating the real meaning of the parametric map. If needed multiple Real-World mappings can be used to communicate different meanings
Reminder for later: see what is already described for “Neuro DM experiments” as it might be used for Paradigm descriptions. The Supplement number 189 was assigned. The Supplement will return. 26. Supplement 190 – Volume Rendering [WI 2008-04-C} This supplement is the third under this Work Item: (1st: Sup 156, 2nd: Sup 182.) This was a presentation of the concepts and a First Read. The WG-11 Team presented the topic by phone: A Klingler, Joe Luszcz, J. Whitby. The concepts were presented by J Whitby with the help of the ppt (posted as VolumeRenderingVPSproposal_v2.pptx.) Thereafter the draft was presented (posted as SupXXX_VolumeRendering_20150909_1530.docx.) The ensuing discussion concluded that examples will need to be added and some ppt slides should be added to an informational annex. The Supplement will return. 27. Supplement 191 – Patient RDSR Storage [WI-2012-11-C] – This was a First Read. Donald Peck of AAPM, Chair of WG-28, presented the Supplement with Francisco Sureda, Chair of WG-02 assisting by phone connection. D. Peck noted that WG-28 and WG-02 work in close cooperation on this Supplement.

The following files, posted in the meeting folder were referred to in this discussion: < WG-28_Patient Radiation Dose SR (P-RDSR)_rev7.pptx> and < WG-28_supXXX Patient-RDSR draft 06 20150824.docx>. The Supplement was assigned number 191. Comments and directions of WG-06 were recorded by D. Peck in the draft presented. At the end of the session the annotated draft was posted in the meeting folder as < WG-28_sup191 Patient-RDSR draft 07 10-2015 End of Session.docx>. The Scope and Field of Application was reviewed. It summarizes the purpose and rationale for this Supplement and is reproduced below. Supplement number 191 was assigned. Supplement 191 is scheduled to return for Reading for Public Comment, at the January 18-22 Meeting of WG-06. Scope and Field of Application Many professional, public-health, and regulatory authorities recommend or require recording dosimetric information from diagnostic and therapeutic studies that use radiation in the patient’s medical records. For non-oncology therapeutic applications, the current Information Object Definitions (IOD) used for measuring the radiation dose indices is the Radiation Dose Structured Report (RDSR). The RDSR contains only information about the irradiation system or information the system can determine, i.e. radiation output, geometry, x-ray source, detector system, etc. Yet, these IOD do not include sufficient information about the patient, which is required to adequately estimate the radiation dose to the patient. In addition, there are multiple methodologies and models that can be used to estimate patient dose and these methods are rapidly changing. Once an estimate of the radiation dose absorbed by a patient is performed, storing and transferring the method used, parameters involved with them, and the resulting dose estimate in standard format will facilitate recording such information. It is assumed that the best location for information relative to the dosimetric method used and the estimated patient – radiation dose should be to send this data to a Dose Information Reporter, an actor (in the IHE sense) that may or may not be combined with a RIS, a PACS, or may be a standalone system. The approach taken here for the Patient - Radiation Dose Structured Report (P-RDSR) is to define a new Structured Report (SR) object template and SOP Class. This SR object, independent of the images or the MPPS, could be routed to an appropriate Dose Information Reporter System. A system that claims conformance to such an SR object would then be expected, as a concomitant of the conformance claim, to appropriately deal with such data items. Such an SR dose object allows the data flow and data management of patient estimated radiation dose reports to be disentangled from the data flow and data management of images.

28. New Business Items 29. New Work Item-CT Sinogram D. Peck, as AAPM representative, reported that a DICOM Work Item is planned for introduction of a new DICOM Storage SOP Class (based in part possibly on a private SOP Class being used by Mayo). The contents of the SOP Class is “sinogram” data (also called “projection” data) from a CT scanner. The sinogram data is the “raw” data that the CT scanner acquires and then reconstructs to produce the image data stored in the CT Image Storage SOP Class today. Kevin O’Donnell suggested to avoid calling the new SOP Class ‘Raw” data to avoid confusion with the Raw Data Storage SOP Class that already exists in DICOM. The existing Raw Data Storage is a DICOM wrapper around a black box. The black box can have arbitrarily contents and be encoded in a proprietary way. It’s useful for using DICOM to move and store black boxes. The Work Item is to define a standard format for sinograms/projection data, not a black box. The purpose is to facilitate 3rd party research into reconstruction algorithms and other things that need the projection data. The draft is posted in the Sups directory of the meeting folder. 30. New Supplement -Supplement 192 - Instance Approval Storage [WI-2006-04-E] WG-06 initiated this supplement as it recognized the commonality of Supplements 121 and 147, and expected other uses outside CT protocols. This Supplement defines a storage SOP Class to convey assertions of approval for Protocols (and other instances). The assertions are encoded using a macro which is also being used for RT. These were originally part of the Sup121 but have been moved into a separate supplement when it was decided they should be a separate SOP Class rather than embedded within the CT Protocol SOP Classes. The supplement number was assigned. See < Sup192(Approvals)_PC+20150909.docx> posted in the meeting folder. It was decided that Sup121 can proceed to LB without Sup 192 is finalized. The supplement will return. 31. Future Meetings
