ABSTRACT:
An improved imaging system produces consistent, high resolution digital images of a region of interest within a patient's breast by optimizing the modulation transfer function of the system. The system includes an array of detector elements and a source, positioned in opposing relation to the detector element array, for transmitting an imaging signal to the detector array with the region of interest positioned therebetween such that the detector array receives the imaging signal. The array is configured for scanning movement such that imaging data is detected and accumulated within the elements of the array during the movement. The detector array is further configured for reading out a portion of the accumulated data in response to a drive input and for internally shifting the accumulated imaging data in response to a shifting signal. The shifting signal is modified in accordance with measured variations in the scanning rate such that a substantially fixed relationship is maintained between the region of interest and the position of the accumulated charge within the array during the scanning movement, irrespective of variations in the rate of scan.
