Mathematical simulation of radiation diagnostics of foreign bodies of lungs of fire origin

Abstract

According to spiral computed tomography, it is difficult to accurately determine the size of a foreign body, due to the observed artifact in the form of "shine" of metal in the tissues. A mathematical model for determining the size of foreign bodies of the lungs of gunshot origin has been developed to improve the results of diagnosis of gunshot wounds penetrating the chest with lung damage. For mathematical modeling of the process of diagnosing foreign bodies of the lungs, we used the dimensions of 32 foreign bodies of lungs of fire origin, detected during spiral computed tomography and removed during surgery. To more accurately determine the length, width and height of a real foreign body, it is necessary to take into account the correction factor, which depends on the X-ray density of the foreign body. Measuring the exact size of foreign bodies allows you to more adequately determine further surgical tactics. Keywords: mathematical simulation, gunshot wounds, lungs, foreign bodies.
