AI Technical Summary

Problems solved by technology

When the X-ray sensing panel is used to obtain dynamic images, due to the shortened exposure and detection time, the intensity of the sensing signal received by the reading circuit will be greatly weakened, that is, the amount of signal that the reading circuit can receive is reduced, and thus The sensing quality of the X-ray sensing panel is greatly reduced, and precise and clear images cannot be displayed

Description

technical field [0001] The invention relates to a detection device, and in particular to a light detection device and a detection method thereof. Background technique [0002] Traditional X-ray medical equipment uses negative film for interpretation and storage. In order to provide better image quality and storage methods, digital X-ray medical equipment can be used. The digital X-ray medical equipment uses an X-ray sensing panel to sense X-rays. Generally speaking, each data line on the X-ray sensing panel corresponds to a reading circuit, and each reading circuit can read the sensing signal on the corresponding data line and transmit the sensing signal to the signal processing device. The processing device can digitize the sensing signal to generate a digital image signal, and transmit the digital image signal to the display device for display. When the X-ray sensing panel is used to obtain dynamic images, due to the shortened exposure and detection time, the intensity ...
