Abstract:
Medical images are an important part of the diagnostic process. In many cases the accuracy of diagnosis depends on the quality of the image. Therefore, the image quality improvement is an essential part of medical imaging techniques. Now the quality enhancement process is divided into two parts: pre-processing, whose task is to optimize the image quality in the process of its creation by digital devices and apparata, and post-processing, whose task is increasing the readability and intelligibility of images on the physician’s computer display. The proposed paper offers a new post-processing method for X-ray image quality enhancement using the theory of High Dynamic Range images (HDR-images). Since one could not get real images with different exposures, four techniques to simulate various levels of image exposures for HDR-image creation are proposed and analysed in the presented paper.
