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
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).

Mammo Image Profile • Acquisition Modality • FFDM & CR are required to create MG objects • Create MG objects as specified • 40 Attributes with specific requirements defined • Including new pixel padding range limit (0x0028,0x0121) • Evidence Creator • Mammo CAD systems • Support Evidence Document Stored with Storage Commitment • Support Mammography CAD SR objects
Mammo Image Profile (cont’d) • Image Manager/Archive • Support both Modality Images and Evidence Document Stored with Storage Commitment • Support Query/Retrieve of both Images and Evidence Documents • Image Display • Support Query/Retrieve of both Images and Evidence Documents • Support specified display capabilities including background air suppression, LUT rendering, zoom management and CAD SR display
Mammo Image Profile (cont’d) • Print Composer • Support Print Request with Presentation LUT • including the LIN-OD presentation LUT shape • Use Requested Image Size to achieve true size printing • Support 12 bits printing • Print Server • Support Print Request with Presentation LUT • including the LIN-OD presentation LUT shape • Use Requested Image Size to achieve true size printing • Support 12 bits printing
Mammo Image contents • Background air suppression • New tag in DICOM (CP692) extending the pixel padding concept • Mammo CR generate MG instances only • specific fields (i.e. gantry ID) have been added to the required attribute list. • Tiled Views option defined • Allows for large breast imaging (multiple images of the same breast)
Image Display • Zoom • Adjust zoom accounting for varying acquisition pixel sizes • True size zoom accounting for display (monitor) pixel size • Background air suppression • When inverting/windowing the image, the detected background stays black • Image orientation • Flipping according to Patient Orientation ((0x20,0x20)) • Annotations • Set of required annotations to be displayed is defined • CAD rendering (using CAD SR)
