This software was developed for assisting users in achieving the physical characterization of X-ray digital systems and some image quality checks. It can be used for calculating various physical parameters such as the response curve, Modulation Transfer Function (MTF), Noise Power Spectra (NPS), Detective Quantum Efficiency (DQE). It also includes the computation of some image quality checks: defective pixel analysis, uniformity, dark analysis, and lag.
