8: Glossary of Terms
Affirm System
The breast biopsy guidance system for the Selenia
Dimensions and 3Dimensions imaging systems
Biopsy Control Module
The user control device for the breast biopsy
guidance system
Biopsy Guidance Module
Holds and operates the biopsy device. Responds
to commands from the Biopsy Control Module to
move the device into position and do the biopsy.
C-Arm Mode
Lets the C-arm and Tube Arm move together to
the Needle Approach angle for the Localization
procedure.
Exposure Technique
Combination of x ray parameters (kVp, mAs,
filter) for an acquired image
Gantry
A part of the Selenia Dimensions and
3Dimensions systems that has the Detector,
Generator and X-ray Source,
Positioning/Compression, Power Distribution, and
Accessories Subsystems
Multi-Pass
Allows you to automatically generate up to five
offset target points all equidistant (up to 5 mm
away) from the original target point
Needle Approach Angle
The angle of incidence of the needle to the breast
QAS
Quality Assurance Standard
Safety Margins
The minimum space allowed between the biopsy
device needle tip that is installed and components
of the system (for example, image receptor or
paddle)
Stereo Mode
Lets the Tube Arm rotate for acquisition of
stereotactic images while the C-arm stays in
position.
Stereotactic Procedure
A type of examination that allows stereotactic
views at the Acquisition Workstation.
Stereotactic View
A specialized image view that causes the
application to capture stereotactic images
Stroke Margin
The safety margin (in mm) which remains
between the fired needle position and the breast
platform. This margin is calculated by the system
according to the "Z" coordinate, the Stroke, and
the compression amount.
Tomosynthesis
An imaging procedure that combines a number of
breast images taken at different angles. The
tomosynthesis images can be reconstructed to
show focal planes (slices) within the breast.
View
The combination of one x-ray image and a
specified set of conditions for image acquisition
