The invention discloses a flat panel light sensor, a flat panel detector and an imaging system, the flat panel light sensor comprises a current collection array, a bias voltage line, a data line, a scanning line and a driving circuit, and the current collection array comprises a plurality of photoelectric sensing units arranged in rows and columns; each bias voltage line is connected with one row or one column of photoelectric sensing units in the current collection array; each data line is connected with a corresponding column of photoelectric sensing units; each data line comprises branch lines with n serial numbers, and the photoelectric sensing units on the same column are connected to the branch lines with the same or different serial numbers; each scanning line is connected with the photoelectric sensing unit in the corresponding row, the driving circuit is connected with the scanning lines and is used for performing time-sharing gating on the scanning lines, and the serial numbers of branch lines connected into the photoelectric sensing units corresponding to the scanning lines gated each time in the same column are different from one another. According to the flat panel light sensor, the flat panel detector and the imaging system provided by the invention, rapid scanning and reading of the photoelectric sensing unit are realized through multi-line parallel scanning.
Description
technical field [0001] The invention relates to the field of medical imaging equipment, in particular to a flat light sensor, a flat detector and an imaging system. Background technique [0002] Amorphous silicon TFT-PD flat panel X-ray detectors are widely used in medicine, industrial inspection, safety inspection, pet treatment and other fields. In actual use, the overall system expects the detector to quickly complete the scanning readout and then image the output, and the longer the exposure time for X-rays, the better, so as to help improve the signal-to-noise ratio of imaging and improve the imaging quality of the sensor. However, the existing amorphous silicon TFT-PD flat-panel X-ray detectors work by scanning and reading out line by line to integrate electrons line by line to output images, so the imaging speed is limited by the scanning time of each line and the total number of rows, it is difficult to greatly increase the scanning and reading speed.
