A device and method for evaluating the performance of X-ray machines used to produce radiographic images is described. An analyzer including an X-ray dosimeter and an imaging device is sent to the facility having the X-ray machine to be evaluated. The analyzer may be used with a film pack or a digital image detector. The analyzer is exposed in accordance with testing instructions and returned to an evaluation agency. The radiation dose and HVL is determined from the dosimeter, and the image quality is determined from analysis of a radiograph of a target having differing X-ray absorption portions. A data base of results may be used to provide comparative analysis. |
