Image Acquisition Procedure
Note:
When the patient is positioned for a Cleavage view (CV), external markers must be used to assist
in determining laterality when viewing the image. Place a Right (R) or Left (L) marker in the lateral
aspect of the breast of interest, or place markers on the lateral side of each breast. Markers must
be placed outside of the 140 mm x 160 mm ROI used by AOP.
• To display the acquired images on the AWS monitor in the same order as films hung in the conven-
tional order on a viewbox, it is suggested that patient images should be acquired in the following
order:
RCC
LCC
RMLO
LMLO.
• When all parameters are correctly chosen and the patient prepared, make the exposure in the usual
way using the Prep and Exposure buttons.
• After the exposure, the image acquired by the Digital Detector is automatically transferred to the
workstation, added to the exam and displayed on the Viewer screen as a raw image. During the
transfer of the raw image all user interface functions are disabled.
• If the FineView feature is enabled, the sharpness of the image is optimized by the use of detector
feedback information. To enable or disable FineView, refer to Chapter 8 Browser, section 8-3 Medi-
cal Application preferences on page 75.
• Processing of the image is started automatically. See below for a discussion of processing consider-
ations.
• The processed image replaces the raw image within a few seconds; it is displayed with the Standard
contrast level, unless the User level has been selected in Medical preferences. The user can choose
a higher or lower contrast level using the View Control contrast setting (see Chapter 11 Viewer).
• As soon as an image has been transferred and displayed on the screen, the system is ready for the
next exposure. The images (first raw, then processed) from the new exposure replace the previous
image in the Viewer.
