Computer-assisted quality assurance for radiographic equipment.

A quality assurance procedure which includes a computer program has been implemented to facilitate measurement of some of the parameters normally tested on diagnostic radiographic equipment. These include: reproducibility of output, linearity of mA settings, filtration, kVp calibration, timer error, SID indication, light field--x-ray field coincidence and effective focal spot size. The user may omit those sections which are not applicable to his needs. Full use is made of the data reducing the number of field measurements needed.
