In this study, we used the method of color contrasting in computed radiography images post-processing. This method is based on the color vision quantum hypothesis and ensures the psychological compatibility between the colored radiography image and the original one. The study was conducted using the example of X-ray computed images of the brain of patients with acute cerebrovascular accident as well as computed radiography images of the chest organs of patients with coronavirus pneumonia. As a result, the diagnostic information was visually optimized after color post- processing of X-ray images. The study showed a qualitative increase in the efficiency of diagnosis of some acute diseases due to the use of our proprietary color contrasting method in the post-processing of X-ray computed images.
