Symmetrical multiple-slice computed tomography data management system

摘要

A data measurement system (DMS) ( 30 ) for a computed tomography (CT) scanner ( 12 ) includes a plurality of connectorized detector sub-array modules ( 32 ). Each detector sub-array module ( 32 ) includes: a scintillator ( 40 ) that produces scintillation events responsive to irradiation by x-rays; a photodetector array ( 42 ) arranged to detect the scintillations; and two symmetrically arranged signal connectors ( 54 ₁ , 54 ₂) that transmit the photodetector signals. Symmetrically mounted pipeline cards ( 60 ) mate with the signal connectors ( 54 ) of each side of groups of the detector sub-array modules ( 32 ) to receive the photodetector signals. A processor ( 64 ) communicating with the pipeline cards ( 60 ) receives the photodetector signals from the pipeline cards ( 60 ) and constructs a DMS output from the photodetector signals.
