Problems solved by technology

[0003] In the prior art, the image contrast noise and other aspects are generally optimized by adopting a set of default image processing parameters, the image processing parameters include image enhancement coefficient, image denoising coefficient and image grayscale curve adjustment coefficient, etc.; There are differences between the actual captured DR images. Using the default parameters for optimization processing cannot be applied to all images. For individual images, fine-tuning of parameters is required during the optimization process, even in some special cases such as high shooting dose or low, resulting in a poor processing effect with fixed parameters, and at the same time fine-tuning the parameters can not meet the requirements, at this time, it is necessary to re-exposure and shoot, so that the patient received unnecessary secondary exposure radiation

Abstract

The invention provides a DR image processing method and device and computer equipment. The DR image processing method comprises the following steps: inputting a to-be-processed DR image into a pre-trained neural network model, and identifying a target human body part contained in the DR image and the quality grade of the DR image by utilizing the neural network model; determining an image processing parameter corresponding to the DR image according to the target human body part and the quality grade of the DR image; and performing image processing on the DR image by using the image processingparameters. The DR image processing method has the advantage that image processing is more efficient and accurate.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular, to a method and device for processing DR images. Background technique [0002] DR (Digital Radiography, digital photography) equipment uses a digital flat panel detector to receive the rays emitted by the X-ray tube. The energy attenuation of the rays passing through objects with different densities is different, so that the rays that reflect the internal structure of the object are received at the flat panel detector. According to The ray is imaged to obtain a DR image. Due to the existence of quantum noise and ray scattering, the photoelectrically converted image signal has a lot of noise, and the contrast of the original image is also relatively low. In addition, the dynamic range of DR images is wide, and all information cannot be presented under a specific window width and level. If you need to observe the detailed information of a certain part, you nee...
