1 SCAR Annual Meeting 2004 Public meeting of NEMA CT-MR Taskforce Saturday, May 22 nd, 7:30 – 9:00 AM

2 Introducing the new Standards Presented by Martin von Roden Siemens Medical Solutions Co-Chair CT-MR Taskforce

3 A new CT Standard Implementation After 10+ years of effective DICOM connectivity in MRI and CT introducing a new Image Object poses three challenges:

4 Avoid user confusion – Avoid user confusion Inform about the benefits of the enhanced multi-frame image standard and need to manage coexistence. Synch-up industry – Synch-up industry Facilitate availability of compatible PACS and Workstations along with the release of the MRI and CT scanners. Reduce incompatibilities – Reduce incompatibilities Provide to interested vendors testing tools and opportunities to quickly retire misinterpretations or bugs. Challenges

5 How to manage the transition... The DICOM Working groups for CT and MR and the DICOM Standards Committee felt the need for an educational program for users and vendors to facilitate the introduction of the new objects.The DICOM Working groups for CT and MR and the DICOM Standards Committee felt the need for an educational program for users and vendors to facilitate the introduction of the new objects.
