SMOC detector is a fluoroscopic device, which allows to perform a digital radiography with direct transfer of images to the operator's PC. The SMOC: GOS (Gd2O2S:Tb) scintillator, front-coated mirror and high quality, well shielded CMOS camera all make use of well-known and proven technology. The achieved resolution is typically 1%. SMOC is designed for high energies, up to 15 MeV. Integrated shielding allows for efficient work with all kinds of radiation sources, including X-ray tubes, Co-60, electron linacs and betatrons. The D-SMOC software which works with the detector has been created for controlling the SMOC detector, as well as for acquiring and processing the images. D-SMOC has an intuitive interface for NDT users and helps in achieving a quick and easy image acquisition. Advanced functions allow for an efficient X-ray examination thanks to the automatic setting of brightness and contrast, artifacts minimization and precise calibration. Results are available for immediate analysis or can be stored for future review.
