The CCD type flat panel detector uses the intensifying screen as the medium, and then digitizes the X-rays through the CCD. We will ignore the specific conversion process, and then we will talk about the advantages and disadvantages of CCD flat panel detectors.
The advantage of the CCD flat panel detector is its high spatial resolution, so that the imaging will be relatively clear and the operability is high. The geometric distortion is small, and the lesions can be better restored. The image is uniform, which is the same as the advantage of less geometric distortion.
But its defects are also obvious, first of all, the conversion efficiency is low, so the X-ray machine needs more power to obtain a clear image. Secondly, the manufacturing process is difficult, the system is complex, and the reliability is low. Therefore, CCD flat panel detectors are currently being phased out.
