Paper Abstract

A method is developed that enables comprehensive and automatic image quality testing of storage phosphor-based computed radiography (CR) systems. The measurements made with this method are both quantitative and objective, and are consistent with the guidelines set forth by the American Association of Physics in Medicine Task Group 10. The method is implemented as a toolkit that consists of a test phantom, a procedure for making controlled x-ray exposures, and software that automatically analyzes phantom and flat-field images then compares the measured results against a set of tolerances. By using this new method, acceptance testing and periodic image quality control testing of CR systems can be performed quickly and efficiently. A complete CR test that includes measurements for three cassette sizes can be finished in about one hour.
