TOR 18FG
TOR 18FG fluoroscopy phantom is a routine test object designed to be used quickly and easily on a regular basis (e.g. weekly/monthly) to provide an ongoing check of imaging performance, particularly those aspects which are most liable to deterioration. After an initial grey-scale check, image quality is measured simply by counting the number of details detected and the number of bar-patterns resolved in the image. An ongoing record of these numbers will reveal any trend towards deterioration in imaging performance.
