Algorithm of filtering of x-ray tomograms by adaptation method of the size of a filter window to local characteristics of the image

Бесплатный доступ

There are many methods which are used for suppression of artifacts of the computer tomography (CT) now. Usually methods appear from scientific community or from the industry. It is possible to find reports on researches or to listen to reports at conferences for acquaintance with methods. Nevertheless, the considerable part of methods of fight against artifacts is patent means or classified technology and isn't available to a wide range.The algorithm of images filtering of a medical X-ray computer tomography with adaptation of the sizes of an aperture and a filtering method to local characteristics of the image is offered. The algorithm is implemented in the form of the software and approved on projectional data of tomographic images. The description of algorithm and the formulas which it is based on is provided. The error of this algorithm is evaluated, comparison with existing methods of filtering is given.
