Abstract

The invention discloses a bone suppression image generation method and a device, a storage medium and electronic equipment. The method comprises the steps of obtaining a chest original image of a target object; processing the chest original image based on a pre-trained bone suppression model to obtain an initial bone suppression image and a bone segmentation image of the target object, the pre-trained bone suppression model comprising a bone suppression branch and a bone segmentation branch; and generating a target bone suppression image according to the bone position in the bone segmentationimage, the chest original image and the initial bone suppression image. According to the method provided by the embodiment of the invention, the obtained target bone suppression image can eliminate the bony contour of the pixel points of the skeleton region, can reserve the original image information of the non-skeleton region, improves the image definition, and reduces the distortion of the bonesuppression model in the chest original image processing process.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image processing, and in particular to a method, device, storage medium, and electronic equipment for generating a bone-suppressed image. Background technique [0002] Digital radiography (digital radiography, DR) is a new digital imaging technology recently developed. It has similar uses to computer radiography (CR), but its basic principles and structures are different. DR is developed on the basis of digital fluorescence photography (digital fluorography, DF). It uses image intensifier tubes as information carriers to receive X-ray information that passes through the human body. After being collected by a video camera, it is converted into digital signals and then digitized. [0003] Chest X-rays are chest X-rays. Routine chest X-ray examinations include frontal, left anterior oblique (60°-65°), right anterior oblique (45°-55°) and left lateral views. Frontal chest radiography ca...
