Abstract
An apparatus is disclosed for imaging a patient's breast (18) by scanning an imaging signal (58) and a receiver (30) across the patient's breast (18) and then constructing a time-delay integration composite image based on the scan. The receiver (30) includes an array of radiation sensitive detector elements (132). Read out of the array (132) is synchronized with the scanning motion of the receiver (30) based on output from position encoder (104) such that synchronization is maintained despite scan drive variances. A novel assembly (106) is also disclosed for allowing selection of an appropriate radiation filter based on particular imaging conditions.
