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

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).

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

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

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)
Feb 7-8, 2007

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)
