Abstract
A detector module is for CT and/or PET and/or SPECT examinations, and includes a number of measuring channels. Each measuring channel includes a direct converter for directly converting incident measuring radiation into analog electric signals, a pulse generator connected to the direct converter, for generating counting pulses as a function of the received electric signals, and a counting device that counts the received counting pulses over a prescribable time period and outputs the result. Arranged between the counting device and the pulse generator is an externally drivable changeover unit that can be used to switch over between the counting device and an event detector that registers and outputs for each received counting pulse the time and the associated measuring channel or an item of location information assigned to this measuring channel. The present detector module is of simple design.
