Single-photon emission tomograpy methods
The research topic is a part of the project for developing a tomographic gamma-monitor for controlling nuclear technical objects. The device must provide localization, quantitative assessment, identification and visualization of radionuclide distribution by the volume of the object under investigation.A comparative analysis of options, algorithms and methods of a single-photon emission computer tomography is given in the paper. An overview of the main tomography objectives is given, and the methods for their solution are briefly considered. In particular, design features of the devices, general issues of the data processing methods, several methods of original structure reconstruction are considered. The classes of tomography problems with a limited amount of data: a few projection and a small-angle tomography are considered. In conclusion, an overview of the properties of tomography systems with coded apertures is given.As a result of studying the tomography methods the conclusion on the most promising implementation of data process- ing algorithm for the designed device was made.
