COMPUTERIZED TOMOGRAPHY IMAGING USING MULTI-SLICE DETECTOR WITH SELECTABLE SLICE THICKNESS

摘要

A computerized tomography system includes a detector array (14) made up of a set of detector subelements (41-48) aligned along a slice thickness direction. A controllable switching matrix (60) selectively interconnects a predetermined number of successive detector subelements to a respective summing amplifier (80) to produce slice-constituent signals which measure a respective slice positioned to pass through a body. Each respective slice having a selectable thickness in a region of interest to be imaged.
