FPGA-based flat panel detector (FPD) with image correction function

Abstract

The invention provides an FPGA-based flat panel detector (FPD) with an image correction function, which comprises an FPGA. The FPGA is internally provided with an original image acquisition module and an image correction module, wherein the original image acquisition module is used for acquiring an original image acquired by the FPD; and the image correction module is connected with the original image acquisition module for receiving the original image acquired by the original image acquisition module and correcting the original image. According to the FPGA-based FPD with the image correction function, the overall image correction process is completed inside the FPD, an image template does not need to be transmitted to a working station, the complexity of an interactive process between the FPD and the working station is reduced, and thus, the stability is improved, the image confidentiality is high, and the software development and integration difficulty of the working station is reduced; and meanwhile, the image correction speed is greatly enhanced, and the overall image acquisition process speed is enhanced.

Description

technical field [0001] The invention relates to the field of flat panel detectors, in particular to an FPGA-based flat panel detector with image correction function. Background technique [0002] In 1995, RSNA launched the first flat panel detector FPD (FlatPanelDetector) device, which is a detector that directly converts X-ray energy into electrical signals to generate X-ray images. In recent years, with the rapid development of flat-panel detection technology, the image quality of flat-panel detectors has been greatly improved, making them more economical and practical. At the same time, the technology, cost and maturity of flat panel detectors have been gradually recognized by the market and widely used in related fields. [0003] At present, flat-panel detectors are widely used in optical medical diagnosis. X-rays are projected onto flat-panel detectors after passing through the human body. Through real-time image processing, image digital signals are directly obtained,...
