<p style='text-indent:20px;'>In this paper, we consider the imaging problem of terahertz (THz) tomography, in particular as it appears non-destructive testing. We derive a nonlinear mathematical model describing full THz tomography experiment, and linear approximations connecting with standard computerized Radon transform. Based on derived models propose different reconstruction approache...

Small-angle x-ray scatter imaging has a high intrinsic contrast in cancer research and other applications, and provides information on molecular composition and micro-structure of the tissue. In general, the implementations of small-angle coherent scatter imaging can be divided into two main categories: direct tomography and angular dispersive computerized tomography. Based on the recent develo...

Purpose: The aim of this report was to evaluate the prevalence implant failure rates due positioning on Cone beam Computerized Tomography. Methods: Study sample (n= 333) consisted CBCT(Cone-beam computerized tomography) scans patients who were referred Department Dentomaxillofacial Radiology, University Health Sciences Turkey, Gülhane Faculty Dentistry, Ankara, Turkey. Obtained data such as age...

We analyzed computerized tomography (CT) findings in six patients with Fahr's syndrome. They presented calcifications in basal ganglia, dentate nucleus, subcortical region and semioval center, due to alteration in calcium metabolism or due to senile relative hypoxemic state. The image pattern was not strictly related with etiology, although some differences in dystrophic senile calcifications (...

In nuclear medicine, there are two methods of imaging, planar and tomography. Single photon emission computerized tomography (SPECT) shows better image details and therefore is influenced more by image parameters such as resolution, uniformity, sensitivity, etc. Manufacturers provide customers with data which are obtained by complicated and sometimes secret methods. Marketing companies te...
