Scatter effects are reduced in a radiographic imaging device, such as a
digital slot scan mammographic imaging device, by reducing detected
scatter and processing detector information to compensate for scatter
effects. A digital mammographic imaging system (10) may include a source
(24) for transmitting a narrow beam (28) and a detector assembly (32) for
detecting the beam (28). The beam (28) and the detector assembly (32) may
synchronously scann across the patient's breast (48) to obtain an image.
Collimator slats (74) at the leading and trailing edges of the detector
may reduce detected scatter. Attenuators (76 and 92) at the ends of the
scanned motion and at the anterior edge of the detector array may assist
in determining a spatial intensity profile. The spatial intensity profile
information together with other imaging signal and patient dependent
parameters may be used to estimate and compensate for various scatter
effects.
