We are familiar with two types of flat-panel detectors, crystalline silicon flat-panel detector and amorphous silicon flat-panel detector. From the perspective of energy conversion, the former belongs to direct conversion flat-panel detector, and the latter belongs to indirect conversion flat-panel detector.
Flat panel detector is a new and high technology, which is used in clinical X-ray photography. The dynamic flat panel detector has high DQE, large tolerance, low exposure dose, high resolution image, fast X-ray conversion efficiency, and reduces the labor load of radiation workers. It can be said that it is a leap in medical image technology. The carbon fiber dynamic flat panel detector has more excellent performance. Under rated condition, the input of newheek flat panel detector changes with the temperature, which is called the temperature coefficient of detector. This parameter is usually used to measure the temperature performance of detector. For the detector image system, the function of temperature drift positive is usually designed, and the method of deducting the drift factor in image processing is used to ensure the stability of image output.
Carbon fiber has high axial strength and modulus, low density and no creep, so it reduces the quality of dynamic flat panel detector, enhances the impact resistance of the device, and is convenient for the movement and carrying of the device. In the non oxidation environment, it is characterized by high temperature resistance, good fatigue resistance, small coefficient of thermal expansion, anisotropy, good corrosion resistance and electromagnetic shielding. It is outstanding in the performance of insolubility in organic solvent, acid and alkali, and improves the service life of flat panel detector.
