The invention discloses a method for adjusting the brightness of a perspective image, which comprises the following steps: determining the target gray scale range based on the performance parameters of the detector; acquiring a first perspective image, and calculating the gray scale average value of the first perspective image; determining the gray scale range of the first perspective image. Whether the gray-scale mean is within the target gray-scale range; when the gray-scale mean is not within the target gray-scale range, send a voltage signal to the high-voltage generator to adjust the fluoroscopy dose, so that the gray of the second fluoroscopic image The mean value of the grayscale is within the target grayscale range. The invention also discloses a device for adjusting the brightness of the perspective image and a computer-readable storage medium. The present invention realizes the comparison between the gray scale mean value of the first fluoroscopy image and the target gray scale range, and directly sends a voltage signal to the high-voltage generator to adjust the fluoroscopy dose, without the need for electronic components such as photomultiplier tubes, photodiodes, and control circuits, reducing The cost of the equipment effectively reduces the time for the image brightness to stabilize.
Description
technical field [0001] The present invention relates to the technical field of medical image processing, in particular to a method, a device and a computer-readable storage medium for adjusting the brightness of a perspective image. Background technique [0002] With the development of society, the pace of life of modern people is relatively fast, the diet is extremely irregular, and they eat more junk food. Coupled with the limited level of exercise, ordinary people are easily troubled by gastrointestinal related diseases. With the continuous development of medical diagnosis methods, digital X-ray fluoroscopy images have been widely used in the fields of clinical diagnosis and medical research, especially in the diagnosis of gastrointestinal functional diseases, which have very important clinical application value. For digital X-ray fluoroscopy, in order to ensure the consistency of the brightness of the fluoroscopy images of parts with different thicknesses, it is necessar...
