Abstract
In this paper, a method for detecting and mapping inhomogeneities in biological tissues using the radio-wave tomosynthesis method is presented. The proposed method of radio-wave tomosynthesis allows us to calculate the three-dimensional distribution of the permittivity of the space under study and, thereby, to detect tissue inhomogeneities and to determine their location and size. Due to their harmlessness for humans, these methods are suitable for dynamic observation of changes in the size of formation, in contrast to x-ray methods, for which regular doses of ionizing radiation are contraindicated. Therefore, the development of non-invasive methods for the search for inhomogeneities in biological media based on radio-wave sounding, which makes it possible to identify pathological formations, is now very relevant.
Highlights
Due to the development of information sciences and computer technology, it has become possible to use the methods of radio-wave tomography as the means of remote nondestructive testing and diagnostics of the internal structure, semitransparent media for radio emission and restoration of the form of opaque objects
To solve the problem of tomography of inhomogeneities in biological medium is used the known method of radio-wave tomosynthesis [3]
With the help of methods and a coaxial measuring cell developed at the department of radiophysics of Tomsk State University, it is possible to calculate the dielectric constant of a biological material as measured in a wide frequency range
Summary
Due to the development of information sciences and computer technology, it has become possible to use the methods of radio-wave tomography as the means of remote nondestructive testing and diagnostics of the internal structure, semitransparent media for radio emission and restoration of the form of opaque objects. Ultrasonic scanners and x-ray tomographs are used to detect tumors in biological tissues, but it is proposed to use a radio-wave tomograph for earlier and safe control of the appearance of neoplasms. In pathological and physiological processes in biological tissues, as a rule, there are changes in their electrophysical properties, and measurement task of which is of considerable interest in various medical applications. This is important for the detection of cancer. The development of non-invasive methods for the search for inhomogeneities in biological media based on radio-wave sounding, which makes it possible to identify pathological formations, is very relevant
