Abstract

The article presents the different types of CT imaging techniques, their analytical capabilities, advantages and disadvantages, in which the main types of CT are considered in detail: X-ray computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET), and PET/CT machines. CT complexes were classified according to their purpose. Trends in the development of tomography complexes are analyzed. The results of the complex observation of computed tomography techniques are presented. Global trends in the development of medical devices have undergone significant changes in recent years. This is due to the emergence of new qualitative requirements for the level of medical diagnosis, which are dictated by the need for early detection of various diseases. At present, the state of medical technology makes it possible to visualize the structural and functional changes of the same organism using devices that have different physical principles of operation. At the present stage, tomography is one of the most informative methods (a layer-by-layer study of the structure of various objects), which provides much more information about each initial size of an object than other well-known medical diagnostic methods. At the moment, several types of tomography are being developed: x-ray tomography (CT), magnetic resonance (MRI), positron emission tomography (PET), electron beam, ultrasound, optical coherence tomography, etc. But the essence of all methods is the same: according to the aggregate information (in CT, this is the intensity of the signals on the detectors, and in MRI this is the intensity of echo signals) obtained from a particular section (layer) of the object, it is necessary to determine Local information, that is, the density of the substance at each point of the section. In various types of tomography and summary information
