Clinical application of different types of flat panel detectors
Because DQ E affects image contrast, spatial resolution affects the ability to resolve image details. For film, it is necessary to select different types of flat panel detector DR according to different inspection positions. The requirements for density resolution are relatively high, as the focus is on observing and distinguishing the density of different tissues for examinations like the chest. In this case, it is recommended to use the indirect conversion flat panel detector DR so that DQE is relatively high and it is easy to obtain a higher contrast image, which further facilitates the diagnosis.
With higher imaging and high spatial resolution requirements, it is sensible to use a direct conversion flat panel detector DR to obtain high spatial resolution images. At present, most manufacturers of digital mammography machines use direct conversion flat panel detectors, but this is precisely because mammography requires high spatial resolution and only direct conversion flat panel detectors can be supported It is because.
