Panoramic radiology quality assessment.
A procedure is proposed for performing noninvasive x-ray quality assessment tests on panoramic radiology equipment. A simple cardboard tube jig eliminates relative motion between the measurement system and the narrow, collimated x-ray beam. Accurate measurements of beam HVL, x-ray exposure coefficient of variation and mA linearity may be obtained. Use of the tube jig permits easy and routine monitoring of these important x-ray parameters as well as consistency checks of tube output. Film/screen contact also should be routinely checked in the clinic.
