Image & Num Reports Access to Radiology Information Portable Data for Imaging Cross-Enterprise Document Sharing for Imaging Feb 7-8, 2007 2 Mammo Image – The Problem Mammography image review relies on comparison with priors increases the occurrence of simultaneous review of images from different systems Multi-vendor Mammography Systems Vary with detector technologies and sizes result in varying image matrices sizes. Vary with contrast presentation methods result in varying image presentation Mammography Image Review requires a minimal set of display features zoom, LUT rendering, hanging protocols Feb 7-8, 2007 3 Example of different image sizes Image Contrast Adjustment VOI LUT Linear LUT MAMMO – Value proposition Minimum contents for the generated DICOM instances Image Data (for processing and for presentation SOP Classes) CAD data (CAD SR) Basic display capabilities of Image displays to suit specific mammography review requirements CAD acting as Evidence Creators Mammography Workflow Managing the process of creating, storing and using Mammography Image content is similar to workflow for other image content (e.g. see Scheduled Workflow and Post-Processing Workflow Profiles).
