Nickles, R J

A method of and circuitry for correcting gamma ray camera data signals for signal processing circuitry is disclosed. Pulses are artificially generated which replicate the data signals produced at the output of photo-multiplier tubes of the gamma ray scintillation camera and are inserted in the gamma ray camera internal processing circuitry in such a manner as to remain distinguishable from the data signals generated by the photo-multiplier tubes. By monitoring the number of artificial pulses produced artificially and the number of such pulses actually counted by the data processing circuitry of the gamma scintillation camera, a factor indicative of the losses of scintillation count in the processing circuitry may be determined.
