【 摘 要 】

In this paper, we describe the modernization of the tomographic scanner based on multi-channel linear gas-discharge detector. We have changed the principle of acquisition the projection data, which allowed to receive a bulk three-dimensional tomographic data instead of single slices of the studied samples. Modified scanner has shown increasing contrast and spatial resolution of single slices. The volume of interest in studied objects has been significantly increased and are as high as 25 000 cubic cm, which is determined by 1536 pixels in high.
