Hello All, DICOM is seeking public comments for Supplement 225 - Multi-Fragment Video Transfer Syntax. Scope and Field of Application This supplement modifies existing video transfer syntaxes to remove the restriction that the video cannot be broken up into multiple fragments. The affected transfer syntaxes are: • MPEG2 Main Profile / Main Level Video Compression • MPEG2 Main Profile / High Level Video Compression • MPEG-4 AVC/H.264 High Profile / Level 4.1 Video Compression • MPEG-4 AVC/H.264 High Profile / Level 4.2 Video Compression Videos of size larger than 2^32-4 bytes have started to appear (e.g. procedure video recordings). Previously, those videos needed to be split into multiple DICOM instances. Instructions for accessing the documents and submitting comments: 1.

Hello all, There is a letter ballot for Proposed DICOM Correction Package #112 (CPack-112) CPs are batched into CPacks for balloting to the DICOM Standard Committee members. Approved corrections are incorporated into the next edition of the DICOM Standard, which is now released 5 times a year, following each WG-06 Base Standard meeting. Correction Proposals may address: • Ambiguities – standard text that is not precise or leads to various interpretations. • Clarifications – to facilitate the interpretation of the Standard but not change the spec • Errata – correction of normative and informative errors. • Inconsistencies – sections of the Standard that contain conflicting definitions. • Omissions – Obvious text was not included in the Standard. The following Correction Proposals, approved by WG-06, are included in this ballot: CP # Title CP-2071 Clarify that Default Transfer Syntax can be rejected by an Association Acceptor CP-2085 Revise Attribute description of Modality in Scheduled Procedure Step Module CP-2099 Clarify JPIP and Resource Category in DICOM Web Services Context CP-2100 Clarify SMPTE Transfer Syntaxes for DICOM Web Services CP-2101 Clarify multiple frames used as tiles in planar ROI CP-2102 Add Whole Slide Microscopy Image Flavor of THUMBNAIL and retire LOCALIZER CP-2103 Add Lymphoid Tissue Segmentation Type CP-2104 Estimated Fetal Weight Discordance CP-2105 ROI measurements for UL Shearwave CP-2106 Cleanup Delivery Rate Unit Description CP-2107 Add repeated acquisition to TID 10003, 10013 CP-2108 Add software grid terminology to CID 10017 CP-2109 Fix issues in Figure A-20 “Performed Imaging Agent Administration SR IOD Template Structure” CP-2110 Clarify value multiplicity of TID 11003 (“Imaging Agent Administration Activity”) throughout several instances of TID 11008 (“Imaging Agent Administration Phase”) CP-2111 Replacement codes for Yttrium microspheres and 99Tc ECD CP-2112 Update procedure codes for prostate MRI CP-2113 Update Specific Character Set defined term descriptions and references CP-2138 Refactoring and extending left ventricular segment models Each proposal specifies the type of correction, the rationale for the correction, the sections of the DICOM Standard that will be changed, and the correction wording. All the balloted Correction Proposals may be accessed at: ftp://medical.nema.org/MEDICAL/Dicom/CP/CPack-112-DocBook/ ftp://medical.nema.org/MEDICAL/Dicom/CP/CPack-112-PDF/ ftp://medical.nema.org/MEDICAL/Dicom/CP/CPack-112-Word/ Please review the documentation and advise if you have any issues, comments, or feedback with respect to Proposed DICOM Correction Package #112 .

Hello all, There is a letter ballot for Proposed DICOM Supplement 160: Second Generation Radiotherapy – Patient Setup and Delivery Instruction Scope and Field of Application - This Supplement specifies two IODs to support workflow management and patient setup for Radiotherapy treatment delivery sessions. The IODs are designed as part of the Second Generation Radiotherapy object framework. - This Supplement introduces an RT Radiation Set Delivery Instruction IOD, which specifies the RT Radiations to be applied for treatment delivery, the order in which they are applied, and some other parameters related to the upcoming RT Treatment Session. - This Supplement introduces an RT Treatment Preparation IOD to specify setup devices, setup procedures and other items related to the setup of the patient prior to the delivery of therapeutic radiation. The First Generation RT Plan IOD contained a Patient Setup Module with a similar content. However, this content may change between the treatment sessions, while the majority of content of the RT Plan, defining the treatment parameters, remains the same. This caused unnecessary proliferation of RT Plan SOP Instances, and compromised fraction counting within a series of dosimetrically uniform treatments. Therefore, the Second Generation RT Radiation Set and RT Radiation IODs do not include such content, but use a separate IOD for this purpose. Information about this supplement can be accessed on the DICOM public server: Word Document format: ftp://medical.nema.org/medical/dicom/Supps/LB/sup160_lb_PatientSetup.docx PDF format: ftp://medical.nema.org/medical/dicom/Supps/LB/sup160_lb_PatientSetup.pdf PowerPoint Overview: ftp://medical.nema.org/medical/dicom/Supps/LB/sup160_lb_PatientSetup.pptx Please review the documentation and advise if you have any issues, comments, or feedback with respect to Supplement 160. The ballot closes August 18th and your feedback is important. Best regards, Joanie Harper
