Digital DR flat panel detectors have a limited service life, usually no more than five years. The number of exposures, the degree of use and the degree of consumption all determine the life of the digital DR flat panel detector.
CCD type, principle: an enhanced screen is used as an X-ray interactive medium to digitize X-ray images through CCD.
Seeing this, everyone has a clearer understanding of the service life of digital DR flat panel detectors.
Different indicators of the digital DR flat panel detector image have different imaging effects. Therefore, in the clinical application process, the digital DR flat panel detector should be selected according to the actual image effect to obtain higher quality images.
Since different digital DR flat-panel detectors can distinguish different tissue densities or density of dense tissue in the tissue, in actual clinical operations, using different digital DR flat-panel detectors at different positions is beneficial to improve image quality.
From the perspective of affecting image quality, its main performance parameters are modulation transfer function and quantum conversion efficiency. The modulation transfer function describes the ability of the system to reproduce the spatial frequency range of the imaging object.
