sion height threshold, or to 25 kV for compres-
sion height values above one-half of the
compression height threshold. When the
Rhodium filter is selected, kV defaults to 28
kV. The exposure terminates at a mAs value
near the selected mAs windows (125 mAs, 165
mAs, 200 mAs, or the AUTOmatic 200 mrad
window for Large Focal Spot or 38 mAs, 50
mAs, 60 mAs for Small Focal Spot or reduced
mA operation), selectable by the operator. The
final kV and post mAs is displayed after expo-
sure termination.
Auto-Filter This mode provides full automatic operation of
all technique factors. The starting kV values
are as listed above in Auto-kV. Upon exposure
initiation, the AEC signal is sampled to deter-
mine if the kV needs to be incremented
upward to provide an exposure within the 200
mAs window, or the 200 mrad window. When
determined by the Auto-Filter algorithm, the
exposure is momentarily interrupted and the
Rhodium filter moves into the beam in place
of the Molybdenum filter. After the kV or kV/
filter has been selected by the algorithm, the
Auto-Time function completes the exposure.
The final kV, post-mAs, and Filter is displayed
after exposure termination.
2.0 Room Requirements
The exam room containing the Affinity mammography unit must meet all local, state, and
federal requirements for conducting x-ray examinations. In addition, the exam room should
provide:
• Ample space for patient, operator, and C-arm maneuvering
• Accessory storage area
• Adequate ventilation & cooling for both equipment & occupants
