Abstract
The increasing role of radiation diagnostics in clinical practice is due to the constant improvement of equipment, improvement of the quality of the images obtained, and more rational use of traditional methods of examining patients. Radically new types of image acquisition and processing include X-ray computed tomography (CT), in which an X-ray tube connected to a data collection system rotates in an axial plane around the patient's body. The narrow X-ray beam emitted by the tube with a width of 1 to 10 mm, passing at different angles through the studied layer at each point, weakens to a different degree, which is captured by the detectors, numerically displayed in the data acquisition system and then processed by a fast processor using the method of back projections [11]. All transverse images obtained in numerical form are fed to the "main" matrix of the computer.
