Abstract

The invention discloses a flat panel detector capable of collecting images by regions and stages. The detector comprises an X-ray collector, wherein the X-ray collector comprises a photosensitive layer, a photodiode circuit and a TFT gate control driving circuit, and the TFT gate control driving circuit is transversely divided into TFT gate control tube groups of a plurality of regions; a control panel, which is electrically connected with a gating drive circuit, a power supply drive module and an analog-to-digital conversion circuit. According to the invention, the photodiode circuit is divided into a plurality of regions from the transverse direction to realize regional control of a TFT gate controlled switch, and the photodiode circuit is divided into analog-to-digital conversion tube groups in the plurality of regions from the longitudinal direction; and meanwhile, a DC-DC driving power supply is combined to separately supply power to the TFT gate control tube groups in the corresponding regions, so that the purpose of regional and staged image acquisition of the flat panel detector is realized.

Description

technical field [0001] The invention relates to the technical field of flat panel detectors, in particular to a flat panel detector capable of collecting images in different regions and stages. Background technique [0002] Traditional flat-panel detectors turn on the TFT gate control terminals line by line, and collect images through analog-to-digital converters. *17 When flat-panel detectors of equal size collect images, open the TFT gate control terminal line by line, and the analog-to-digital converter collects images line by line according to the order in which the gate drive chip opens the TFT gate control. This kind of flat-panel detector is limited by the TFT gate control Open the sequence, you cannot arbitrarily select the imaging area and collect images in stages according to your needs. Contents of the invention [0003] The object of the present invention is to provide a flat-panel detector that can collect images in different regions and stages, so as to solv...
