Abstract

The invention relates to a flat panel X-ray sensor and a driving method thereof. The flat panel X-ray sensor comprises a plurality of scanning line groups and a scanning control circuit, wherein each scanning line group comprises at least two scanning lines, and one end of each scanning line is connected with a switching element; the scanning control circuit comprises at least two control ends and a plurality of output ends; the control ends are used for controlling the connection with the switching elements; and each output end is connected with all the scanning lines of one scanning line group through the switching elements. The flat panel X-ray sensor provided by the invention has the advantages that the number of the output ends of the scanning control circuit is reduced; and the manufacturing cost is lowered.

Description

technical field [0001] The invention relates to a flat X-ray sensor and a driving method thereof. Background technique [0002] The flat-panel X-ray sensor is a device that converts X-rays into electrical signals according to the light intensity. After X-rays irradiate the object and penetrate the object, the light intensity changes through absorption, scattering, and reflection. The different light intensities in different areas indicate the differences in the internal structure of different areas of the irradiated object. The X-rays that pass through the irradiated object are converted into corresponding electrical signals by the flat-panel X-ray sensor, and finally a grayscale image directly related to the internal structure of the irradiated object is realized. Therefore, the flat-panel X-ray sensor realizes the non-destructive internal imaging of objects, and is one of the best methods for non-destructive testing. It has been widely used and developed in medical imagin...
