Abstract
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 () may include a source () for transmitting a narrow beam () and a detector assembly () for detecting the beam (). The beam () and the detector assembly () may synchronously scann across the patient's breast () to obtain an image. Collimator slats () at the leading and trailing edges of the detector may reduce detected scatter. Attenuators (and) 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.
