Direct x ray flat panel

In order to understand the performance parameters of direct x ray flat panel, it is necessary to have a basic understanding of its structure principle.
The main performance of x ray flat panel has four aspects: quantum detection efficiency spatial resolution, modulation transfer function, and system noise.
For the same x ray flat panel, the quantum detection efficiency varies with different spatial button resolution. The expression method of quantum detection efficiency is usually expressed by the ratio of the square of the output signal to noise ratio and the square of the input signal to noise ratio.
The quantum detection efficiency mainly reflects the density resolution of thex ray flat panel.Since the conversion efficiency of photoelectric signals has an impact on the efficiency of quantum detection, the structure of photoelectric conversion affects the efficiency of quantum detection.
Because the X-ray conversion mode of x ray flat panel depends on the electron hole pair of amorphous selenium, its quantum detection efficiency depends on the charge generation ability of amorphous selenium.
