Abstract
The design and implementation of a program to investigate remote quality assurance testing for film mammography is described. The measurements included tube output, X-ray machine and processor stability and film image quality. Mammography phantoms and film sensitometric strips were distributed monthly to 24 regional hospitals. Most of the hospital processors and X-ray machines performed in a stable manner during the 12 mo. test period. X-ray machine useful beams apparently could be reliably measured using nonscreen films. The main utility of the phantom was to identify cases of poor image quality. The measurements performed on the phantom image could not be used to diagnose specific causes of poor images. [The use of the mammography in the diagnosis of human breast neoplasms was discussed].
