Abstract

The embodiment of the invention discloses a processing method, device, system and storage medium of an X-ray image, wherein the processing method comprises that the image to be processed, which contains target tissues and a foreign object, is obtained, wherein the difference between the pixel gray value of the foreign object and the pixel gray value of the target tissues is beyond the determined range; the pixel gray value of the foreign object is adjusted to make the difference between the pixel gray value of the adjusted foreign object and the pixel gray value of the neighboring target tissues is in the determined range, and therefore a target contrast image can be generated; first preset post-processing is conducted on the target contrast image to generate the result image, wherein thefirst preset post-processing contains high-frequency filtering. The method solves the problems in the prior art that the pixel pray value of the foreign object can weaken or strengthen the pixel grayvalue of the neighboring target tissues because of the foreign object in the high-frequency filtering image, and thus make the neighboring target tissues present an gloomy shadow or bright shadow, andthen the quality of the fused image can be improved.

Description

technical field [0001] Embodiments of the present invention relate to image processing technologies, and in particular to an X-ray image processing method, device, system, and storage medium. Background technique [0002] In some clinical application scenarios of digital mammography, such as two-dimensional puncture applications, high-density, high-attenuation metal puncture needles will be introduced into breast images; Therefore, filtering is an inevitable step in the image processing process. Existing filtering processing methods will cause obvious dark shadows to appear in the target tissue adjacent to the puncture needle after high-frequency filtering, thereby affecting clinical diagnosis. [0003] Such as Figure 1A As shown, in the low-frequency image generated by the high-frequency filtering method of the prior art, a dark shadow appears in the target tissue in the neighborhood of the puncture needle; Figure 1B As shown, based on Figure 1A In the high-frequency i...
