Detective Quantum Efficiency (DQE) is considered the best metric for image quality evaluation in digital detectors. Unfortunately, it is not easy to assess without a specific software tool. The lack of a reference utility for comparing different data from the different devices led us to build our own tool which calculates DQE curves following IEC standards (IEC-62220-1-1 and IEC-62220-1-2, mammography oriented). MIQuaELa displays graphs corresponding to ESF, LSF, MTF, NPS 1D and 2D, NNPS and DQE, likewise, DQE and MTF values are averaged following IEC standard. It also includes several add-ons to compare data calculated prior to IEC standard publications. Data export for further analysis is achieved in two different ways, .xls (Excel) or .mat (MATLAB). Efforts have been focused on developing a simple tool so as to become an adequate solution for routine QC of digital X-ray systems.
