TEST PHANTOMS IN DIGITAL RADIOGRAPHY

At present two techniques for digital radiography are available: stora ge phosphor radiography and image intensifier radiography. In Mannheim test phantoms have been used for evaluation of performance characteri stics and for quality assurance measurements for two years. Different methods were developed for digital image intensifier radiography, but they can be transferred to digital storage radiography. The aim of our test phantom measurements was the development of effective test proce dures for performance characteristics and quality control, which are e asy to handle with limited additional equipment, not time consuming an d representative for clinical imaging. A summary of results and experi ence is given.
