ABSTRACT:
A digital modality modeling system includes a computer with a digital memory adapted for storing patient densitometry information, an input and an output. An input subsystem includes a pair of source/receptor units mounted on a signal positioning subsystem, which is adapted for moving the source/receptor units through predetermined paths of movement, which can be circular or linear. The resulting tomographic data is synthesized to form any 3-D model or image, which is output for further analysis. A digital tomosynthesis method includes the steps of moving a pair of sensor/receptor units relative to a patient. The resulting signals output by the receptor are digitized and synthesized to form a 3-D image or model. Multiple depths of penetration and multiple widths can be captured from single acquisitions using digital tomosynthesis signal processing techniques.
