Paper Abstract

μ-tomographic images are obtained for few soft materials with multi-structure, cylinder with holes of different diameter and biological soft tissue. 2D images are obtained in the transmission mode. 3D images are reconstructed with the use of the 2D slices for visualization of the internal structure. In addition, we used few simple geometrical approximations, for example, total geometrical efficiency, solid angle contribution and gradient. We obtained a series of images in the region 24-27 keV. 3D visualization of the materials is processed and analyzed the results. The present study is also focused on few geometrical considerations in order to design the collimators in front of the fluorescent source to improve the geometrical efficiency.
