Abstract:
This article describes the evaluation of a commercial device designed to assess the performance of phototimers on x-ray systems. The device consists of a digital readout meter that can be connected to a radiographic or mammographic test cassette. Results showed that the device provided reproducible results with different x-ray generators and processors. The device can be used in acceptance testing and routine quality control inspections, as well as to calibrate or adjust phototimers.
