Methods of processing and image compression in an X-ray micro tomographic scanner

摘要

The article is to study operating procedures of an X-ray micro tomographic scanner and the module of 3D-image recovery and analysis of the test sample in particular. Initial data compression and filtering algorithms, based on shadow projections are presented. The main attention of the paper is paid to saving resources of the computer system during the X-ray tomography. This is achieved by pre-processing of the initial shadow projections. Preprocessing includes getting rid of the background noise in the image, which reduces the amount of shadow projections and improves the efficiency of the group compression of shadow projections. The calculations supporting the effectiveness of these methods described, as well as examples of the original and processed images are presented.
