Breast Tomosynthesis
Introduction
Synapse breast tomosynthesis combines digital mammography and computer reconstruction algorithms to provide 3D images. You can view the 3D images as a series of thin high-resolution slices displayed individually or in cine multiframe mode using the Cine tool.
Synapse provides factory reading protocols for mammography. Some of these factory reading protocols might support the display of tomosynthesis depending on the tomosynthesis vendor and user reading protocol preferences.
Standard Image View Support
Breast tomosynthesis supports the display of images and frames for breast bounds calculation and display. Breast tomosynthesis supports 3D breast tomosynthesis and 2D representations for these common standard image views:
- Left cranio-caudal (LCC)
- Right cranio-caudal (RCC)
- Left mediolateral Oblique (LMLO)
- Right mediolateral Oblique (RMLO )
- (2D Mammography Tomo images only) Individual slice thickness, derived from the DICOM data, is displayed adjacent to the slider
Synapse orders the breast tomosynthesis series as follows:
- From foot to head for CC, XCC's
- From lateral to medial for MLO, ML
- From Medial to Lateral for LMO, LM
- All other series keep the current order based on image number
Viewing Synthetic Images
A synthetic image is a computer-generated image that is the by-product of an existing scan. If synthetic images are included in a series, they are the last images included as you scroll through the Viewport.
To easily identify synthetic images, they are labeled in the text overlay, based on the image types, as shown in the following examples:
- Hologic: RCC C-VIEW
- GE studies: RCC V-PREVIEW
- Fujifilm: RCC S-VIEW
Any synthetic images that exist for a study are merged into one thumbnail in the Series Picker. If the RCC includes one 2D FFDM and one synthetic image, the thumbnail includes two images.
