Computer Spatially Oriented Reconstruction of A 3D Heart Shape Based on Its Tomographic Imaging

Abstract

Abstract. Diagnostics of cardiovascular system conditions and diseases is considered the most important task of electrocardiology. The aim of the study is to define geometric parameters of the patient heart and the synthesis of a realistic three-dimensional heart image based on a series of two-dimensional images obtained by computer tomography. The preparation and further processing of medical image data is an important initial step for further study of the heart electrodynamic activity. The problem is solved with the help of computer tomography method by preparing a series of images of the patient heart. The technique of volumetric rendering is applied to represent certain anatomical structures in a three-dimensional (3D) graphical form. It is concluded that the character of the obtained three-dimensional model of the patient heart is determined by the quality of the input data, the resolution of the tomograph, the tomographic slice thickness, the accuracy of the object boundaries determining the segmentation process and the peculiarities of medical image processing by the software applied.

Analyzing the thermal regime of power supply units in portable betatrons by using infrared thermography

“…Portable betatrons are widely used in various industrial sectors as sources of electrons and X rays, in particular, for nondestructive testing of materials, components and installations, examining luggage and cargo at airports, sea ports and heavy truck check points, performing X ray computer tomography and treating malicious tumors in medical practice [1][2][3][4]. The known advantages of betatrons are their relative simplicity and low mass compared to other types of high-energy X ray sources, as well as in-use comfort and low cost.…”
