Performance evaluation of image-intensifier tubes.
A series of image quality measurements were obtained over a two-year period for eight image-intensifier tube fluoroscopic units used in clinical practice. The measurements were in agreement with a radiologist's opinion of the image quality for each tube. The results showed that some systems did not change significantly over the two-year period, while others deteriorated from acceptable to unacceptable image quality during this time. For this reason, it is recommended that measurements be obtained for all diagnostic fluoroscopic equipment at least semiannually to monitor image quality and remedy any changes before diagnostic accuracy is severely affected.
