Description
Summary:An experimental comparative study of the efficiency of three methods for measurement of the resolution of digital radiographic systems is described. An algorithm for subpixel angular projection was constructed. This algorithm allows the resolution of X-ray camera and test object to be measured using a narrow slit and sharp edge. Test results obtained using various methods are compared.
