![]() ![]() This study also includes validation of the new software, based on comparisons of results obtained for the same set of data with two other, freely available programs. The program was successfully tested using DICOM images obtained from mammography units from different manufacturers. The code is available freely, as a compiled, executable file (.exe). Results are immediately displayed diagrammatically, and complete output data are exported to a. A graphical user interface (GUI) and further add-ons make this software more user-friendly. Python-based software was developed that contains modules to calculate inverse conversion function, modulation transfer function (MTF), noise power spectrum (NPS), and DQE itself. This study describes new software created to perform detective quantum efficiency (DQE) calculations fully compliant with the IEC 62220–1-2 standard. The advent of this technology also makes it possible to implement computational methods for quantitative image analysis. Significant improvements in mammography systems have been achieved with the introduction of active matrix flat-panel digital detectors. The authors validated the software by comparing MTF and NPS curves on a common set of images with those obtained with other dedicated programs, achieving a very good agreement. The plugin can run on any operating system equipped with ImageJ suite. The plugin, together with a brief user manual, are freely available and can be found online (With our plugin users can estimate all three most important parameters used for physical characterization (MTF, NPS, and also DQE). This software is potentially beneficial to a variety of users: physicists working in hospitals, staff working in radiological departments, such as medical physicists, physicians, engineers. Various published papers made use of the outcomes of the plugin. It was tested for achieving the physical characterization of several clinical systems for digital radiography and mammography. The software was made available in 2009 and has been used during the last couple of years by many users who gave us valuable feedback for improving its usability. It also includes the computation of some image quality checks: defective pixel analysis, uniformity, dark analysis, and lag. The software can assist users in calculating various physical parameters such as the response curve (also termed signal transfer property), modulation transfer function (MTF), noise power spectra (NPS), and detective quantum efficiency (DQE). The program was developed as a plugin of a well-known public-domain suite ImageJ. Improved circuitry design increases DQE performance 20% with a 0.In this paper, the authors present a free software for assisting users in achieving the physical characterization of x-ray digital systems and image quality checks.This feature allows faster image acquisition for trauma use and uninterrupted exam completion if wireless signal is hindered. ![]() The detector also features internal memory that stores up to 100 images with or without a live connection to the workstation. The entire detector is layered with antibacterial nano-coating to reduce colonization or bacterial growth on the device. The sealed smooth surface and the battery compartment have been designed to lock out moisture. The shape of the detectors incorporates tapered edges to simplify positioning under the patient and an IPX-6 water resistant rating. The new detectors are 20 percent lighter than previous models and feature a revolutionary sleek magnesium alloy enclosure for improved durability. and 17 x 17 in., Fujifilm will begin shipping the new detectors in the United States in early 2015. Novem– Fujifilm Medical Systems will introduce its latest digital radiography detectors, FDR D-EVO II at t the Radiological Society of North America (RSNA) in Chicago, Ill.
