1 Whats New in DICOM Robert Horn Agfa Healthcare

2 Significant Extensions Upgrades to existing modalities Additions of new modality objects Safety and Security User Interface support Coordination with other standards

3 Upgrading Modalities First, MR Then, CT Then, XA/XRF Now, 3D Xray Continues use of multi-frame with functional group macros to capture more frame to frame relationships than just time. Continues use of multi-frame with functional group macros to capture more frame to frame relationships than just time. Concatenations for improved network performance and streaming Concatenations for improved network performance and streaming Incorporate standard DICOM attributes to describe the 3-D information gathered by modern X-ray equipment. Incorporate standard DICOM attributes to describe the 3-D information gathered by modern X-ray equipment. Tomographic Synthesis, etc. supported Tomographic Synthesis, etc. supported Letter Ballot (October 2006) Letter Ballot (October 2006)

4 Ion Therapy A new SOP class to describe the use of ion beam radiation therapy machines. Extensive detail on beam setting options Extensive detail on beam setting options Enhancements to patient position and fixation devices that will be retrofitted to other therapy systems. Enhancements to patient position and fixation devices that will be retrofitted to other therapy systems. Fits into the therapy workflows already defined for other kinds of radiation therapy machines. Fits into the therapy workflows already defined for other kinds of radiation therapy machines.

5 CT/MR Cardiovascular Report An evidence document that captures measurement data derived from either CT or MR observations of the cardiovascular system. The report incorporates; Patient characteristics Patient characteristics Relevant images references Relevant images references Procedure summaries Procedure summaries Automatically as well as manually detected findings Automatically as well as manually detected findings Information about the progress of finding properties over time (by comparison with predecessor preceding reports) Information about the progress of finding properties over time (by comparison with predecessor preceding reports) Observational Conclusions Observational Conclusions

6 Radiation Dose A structured report to describe the radiation dose from various forms of projection X-ray devices: CR, DX, Angiography, Flouroscopy, etc. Three levels of detail for the description Three levels of detail for the description Based on recent IEC recommendations for reporting radiation dose Based on recent IEC recommendations for reporting radiation dose Addition of CTDIvol information to both the old and the new CT objects. More extensive structured report, like that for projection radiography, awaits agreed recommendations from the CT radiation dose experts.

7 Radiation dose (contd) Patient records reports are not defined. The structured report describes the dose from each individual irradiation event so that overall patient dose can be analyzed. Radiation dose reports can describe any irradiation event, and need not correspond to diagnostic studies.

8 JPIP A transfer syntax is defined for supporting the JPEG Progressive Interactive Protocol. This syntax is intended for supporting interactive access to large images or over slower links, and is not well suited to transfer of complete images with full fidelity.

9 Retirement When features are retired from DICOM it means: We remove them from the subsequent publications of the standard, so old versions of the standard should be archived. We remove them from the subsequent publications of the standard, so old versions of the standard should be archived. We stop maintaining those features for fixing problems or coordinating additions to the standard. We stop maintaining those features for fixing problems or coordinating additions to the standard. Features are retired because: They are not being used They are not being used They might be redundant with existing or new objects They might be redundant with existing or new objects They are not recommended for implementation by new products. They are not recommended for implementation by new products.

10 Retirement (contd) Retirement candidates are: Basic Study Content Notification Basic Study Content Notification Detached Patient Management Detached Patient Management Detached Study and Study Component Management Detached Study and Study Component Management Detached Results and Interpretation Management Detached Results and Interpretation Management Print Queue Management Print Queue Management Stored Print Stored Print Standalone Overlays, Curves, VOI LUT and Modality LUT Storage Standalone Overlays, Curves, VOI LUT and Modality LUT Storage Multi-Referenced File Directory Record, and TOPIC Multi-Referenced File Directory Record, and TOPIC Floppy disk and obsolete MOD formats and profiles Floppy disk and obsolete MOD formats and profiles Patient Study Only Query Patient Study Only Query Curves Curves Print Overlay Print Overlay Overlays in images in high bits Overlays in images in high bits

11 Segmentation This supplement defines voxel oriented tissue segmentations. Segmentation allows fractional voxel assignment: e.g, 60% blood, 30% bone, 20% tissue. IOD defines algorithm names and source data used. It does not include algorithm specifications. IOD does not define presentation or visualization parameters. A surface based segmentation IOD is in preparation.

12 Deformable Spatial Registration This is an extension to the already define rigid spatial registration An array of deformation mapping vectors is provided. Deformable registrations are not expected to be reversible in general. If the registration is to be used reversibly, two registration IODs are needed.

13 Unified Procedure Steps Recently out for Public Comment Merges Worklist Management/Performed Procedure Step A single IOD that combines both scheduled and performed attributes A single IOD that combines both scheduled and performed attributes C-FIND to query worklists C-FIND to query worklists N-CREATE to create new procedure steps N-CREATE to create new procedure steps N-GET/N-SET to update N-GET/N-SET to update N-EVENT-REPORT to monitor and report progress N-EVENT-REPORT to monitor and report progress Intended to meet the needs of Radiation Therapy Scheduling and Monitoring Radiation Therapy Scheduling and Monitoring Scheduling and Monitoring CAD systems Scheduling and Monitoring CAD systems Proposed new scheduling activities Proposed new scheduling activities

14 RT Worklist First usage of Unified Procedure Step Out for public comment Provides automated worklist management for the integration of multi-site and multi- system radiation therapy.

15 Substance Administration Verification of Substance Administration Support 5-Rights process Support 5-Rights process Operational Concept Operational Concept Scan patient ID (bracelet, etc.) Scan patient ID (bracelet, etc.) Scan substance (drug, etc.) Scan substance (drug, etc.) Query for permission to administer Query for permission to administer Receive YES, Warnings, or NO Receive YES, Warnings, or NO Substance Information Query Scan substance Scan substance Obtain substance description and documentation Obtain substance description and documentation Assumes existance of an external Patient/Substance Information system that monitors prescriptions, administrations, allergies, etc.

16 Encapsulation of CDA Similar to encapsulated PDF Encapsulates HL7 CDA documents, providing a few crucial extracts (e.g. Patient ID, Document Title) so that a DICOM PACS archive can be used to storage and retrieve HL7 CDA documents.

17 Veterinary Extensions These extensions rephrase the definition of some existing terms, like patient name to accommodate typical veterinary usages. These extensions add attributes for breed, digital identifier, etc.

18 Tracking IT Improvements IPv6 support Small network configuration management Transport ZIP file format to hold DICOMDIR and DICOM files ZIP file format to hold DICOMDIR and DICOM files transport transport

19 New efforts Enhancements to Query and Retrieve Pathology (especially revisions and clarifications to the specimen model) Structured Display Colon CAD Display Calibration communication Breast Tomosynthesis Very Large Images (full slide microscopy) Surgical Support (very long term) Application Hosting

20 Web Site Presentations (like this one) Presentations (like this one) Drafts, Minutes, etc. Drafts, Minutes, etc. Public Comment Documents Public Comment Documents Letter Ballot Documents Letter Ballot Documents The Approved supplements and CPs The Approved supplements and CPs The full DICOM Standard The full DICOM Standard Publicly available
