Review of Physicotechnical and Functional Scanning Parameters on Modern Cone-Beam Computed Tomographs

Abstract

Relevance. Cone beam computed tomography (CBCT) is widely used in dentistry and other fields of medicine due to the high image quality and low radiation load. Advanced models of tomographs allow for studies of various anatomical areas, which emphasizes the importance of understanding changes in their physical and technical characteristics for an optimal ratio between image quality and radiation load.

Review. The article analyzes the physical, technical and functional parameters of scanning various modern cone-beam computed tomographs (CBCT), which are available in the public domain — central printing or presented on the official websites of manufacturers. As part of the study, data were collected and analyzed on the physical, technical and functional parameters of 11 cone-beam tomographs from various manufacturers equipped with a tomographic table or having the possibility of retrofitting with a tomographic table for conducting research with the positioning of the object of study in a horizontal position. The data obtained were compared with the parameters of cone-beam tomographs used to study the maxillofacial region.

Conclusions. The design features of the new generation of cone beam tomographs increase the variability of functionality, contributing to the expansion of the range of diagnostic techniques. There is no information in open sources about the distances between the emitter and the detector, as well as the object-detector distance, which makes it impossible to draw conclusions about the mechanical and physical solutions in cone beam tomographs, which significantly affects the quality of the images obtained.
