Thus, for example, on a 16-channel multi–detector row CT scanner with a 24–detector row hybrid-array design in which the detector has 16 0.75-mm-wide inner rows and eight 1.5-mm-wide outer rows, when a 24-mm-wide incident beam that covers all 24 rows is used, the effective detector thickness will be 1.5 mm ... WebDec 11, 2013 · Calibrating a photon-counting detector can include receiving a reference signal, by circuitry, where the reference signal is measured by a reference detector that measures an output from an X-ray tube. Determining circuitry can then determine, for a detector channel of the photon-counting detector, a mapping between a first true count …
