Paper Abstract

Measurements of the time variations of kVp and exposure rate during diagnostic x-ray exposures give valuable information about faults in generators and about the radiation exposures to the patient. Simple solid state devices which display these parameters as a trace on a storage oscilloscope have been developed. Measurements have been made of their linearity, sensitivity and energy dependence. These have been used to optimize the design of devices suitable for measuring the exposure and kVp at the collimator, as well as the transmission of x-rays through grids and the patient.
