4.8 FAST Compression Mode
4.8.1 How the FAST Compression Mode Works
The Fully Automatic Self-adjusting Tilt (FAST) Compression Mode is for use when
the composition of the breast tissue does not allow uniform compression across the
complete breast with a flat compression paddle. For these patients, not enough
compression can cause an image to appear to be out of focus at the anterior region
from both involuntary motion and not enough compression.
The FAST Compression mode used with this type of breast provides these features:
• Reduced motion artifacts, because the compression is more effective.
• The compression is more uniform from the chest wall to the nipple.
• Maximum patient comfort, because over compression at the chest wall is
prevented.
When the FAST Compression mode is selected, the paddle automatically tilts when
the compression is applied. The paddle starts at the flat position until some
compression force is applied. The paddle then tilts until its maximum angle is
reached.
The FAST Compression mode does not require excessive compression, but you must
use enough compression to prevent the movement of the breast. You should use a
consistent amount of compression, especially for related left and right views.
The FAST Compression mode may not be best for breasts that are equal or
symmetrical in thickness from the chest wall to the anterior area of the breast.
