The wide range of variables in the x-ray imaging process makes it important to be discriminating when establishing a routine quality control program. In Ontario in particular, the value of such a program will be subject to close scrutiny. This paper considers those measurements which have been found to have some benefit, either economically or in improved picture quality, and questions the value of many routine checks which have been recommended. In particular it suggests that measurement of x-ray waveforms may be very significant both in quality control and in detecting equipment malfunction. The justification of a control program in terms of radiation safety and economics is considered briefly.
