The Secretary thanked the WG Chairs for providing more written reports than for any DSC meeting in known history. The highlights of the additional verbal reports follow: 5 DICOM Standards Committee 2014-12-04 WG-01 Requested cancellation of three Work Items because the champions are no longer active: 2006-04-A, 2009-04-A, 2012-04-A. The Chair will update the strategy document Accordingly. WG-03 D Clunie reported on including the new Sup 159 in IHE. WG-05 Discussed that DICOM will not define another media type. It was asked whether ECG should be retired. No decision made. WG-07 D. Clunie noted that there are draft profiles in IHE-RO, frozen and in trial implementation but do not reach final implementation. WG-08 Sup 155 is being developed with good engagement from radiologists. C. Kahn reported that RSNA is asking for equipment features to move information into EHRs. ACR’s Imaging 3.0 was mentioned. Overall observation was that implementations are still lacking. WG-09 has been identified with old supplement 2009-04-B. A decision is needed on moving forward with or canceling this Work Item. WG-10 discussed the national deviations (e.g. Chinese characters). It was stressed that DICOM must be responsive to such requests and handle them expeditiously otherwise DICOM will be fragmenting into national editions published by others. Discussed the Chinese translation (See WG-29 minutes (Dec. 2, 2014) Additionally it was noted that the new formats (docbook, etc) facilitate more translations. Spanish was mentioned as a potentially desirable translation goal. D. Clunie referenced a public meeting on HER. WG-24 (Surgery) produced 4 supplements, recently started IHE Surgery. By mid-2015 the 15-20 profiles currently under discussion, will be reduced to 3-4. The Chair H. Lemke opined that imaging manufacturers are trending toward image guided navigation which may require additional DICOM supplements. Surgeons speak of ‘image guided interventions”. Also noted a movement from diagnostic imaging to therapeutic modeling. WG-11 Planar MPR Sup 156 is in LB. Curved MPR is presenting for PC. In January. WG-12 Sup 169 was approved for LB, waiting for LOINC Codes. Preparing LOINC submission. WG-13 D. Clunie reported on CP draft for color management but noted that that it only scratches the surface of the color management issues. L. Tarbox reported on a new AAPM TG in this area. WG-16 D Clunie explained DTI. Supplement is on first read in January. WG-18 Several CPs arose from Sup 172. WG-20 FHIR has positive implications for integration with DICOM web services. Integration between DICOM and HL7 is in IHE. FHIR’s imaging resource selections are essentially KOS ad Imaging Study. FHIR is in trial implementation. Next draft for trial implementation is May 2015.Balloting for normative standard will be in 2016. WG-21 – reported on continuing new work on Multienergy CT Object Storage. User review of Sup 121, Protocol Storage is underway. WG-22 The DSC Cancelled the Crestal Implant Storage SOP Class. Work Item 200703-D (Sup 138). ISO TC 106 is doing “DICOM work.” RDSR work for CBCT will ask for help from WG-28. CP 375 is the longest running CP, awaiting SNOMED Codes in January. Reported work on CP for 3dXR Object for dentistry. WG-23 Needs to be done: Application hosting update (RESTful). New Work Item in 2016. 6 DICOM Standards Committee 2014-12-04 WG-26 ACTION discussed that a renewed letter from Aperio is needed to recommit to licensing as in the DICOM Patent agreement. WG-27 – Reported 10 more potential improvements to DICOM Web Servies. Proposed changing the name of Part 18. DSC decided against changing Part 18 name to DICOMweb but suggested to add DICOMweb in parentheses. Will process it via the CP process. WG-29 – Reported briefly on ongoing talks with PennApps Hackathon for holding DICOMweb 2015 mini DICOM conference and hackathon with PennApps. Reported on successful Chengdu one-day Workshop. 6. Related Organization Reports – DICOM Related Activities 6.1 CIMICS reported on status of DICOM in China (see presentation posted.) 6.2 JIRA, JAHIS, and JSRT reported on activities (See ppt in meeting folder.) 6.3 ACR reported on “ACR Select” (Appropriateness Criteria.) and on “Imaging 3.0”, “ACR Common” and “ACR Connect”. The DSC decided that the latter requires monitoring to detect whether ACR is moving toward competing with its own standard, DICOM. 6.4 Report on IEC 62B – Radiation Protection continues to dominate. 6.5 ISO TC 215. No development on the review of ISO 12052. Reaffirmation would only cover up to Part 17. Need to add the other Parts, as well. 6.6 JIC was set up to coordinate development of standards between ISO and other SDOs. Secretariat – SNOMED, Chairman is Jane Millar. 6.7 Taiwan – DICOM is popular. Focusing on training for administrators. 7 DICOM Standards Committee 2014-12-04 7.
