[Mathematical algorithm for constructing optimal standard descriptors for differential diagnostics of chest organ diseases].

This paper presents a mathematical algorithm based on constructing optimal standard descriptors to reduce the major causes of medical errors in groups of patients with chest diseases. It was shown that the mathematical algorithm based on the results of correlation analysis mand calculation of the prognostic sum of descriptors for the study (medical errors) and control (no medical errors) groups allows a new patient to be referred to either group. A computer program based on the mathematical algorithm enables it to be applied to determining group affiliation of the patients. In the process of further research the volume of descriptors in the standard can be increased to improve the accuracy of decision-making by a physician.

The authors propose a procedure and equipment for control by using a rotation table of a PYM-20M X-ray system with an image intensifier. A 4 x 4-cm beam field is used. The procedure makes it possible to lower X-ray loads in patients by 10-15 times, to calculate the absorbed integrated radiation dose, to enhance the quality of plane films, to draw up a protocol of studies. This increases the accuracy of X-ray anatomic instrument position. The apparatus can be remotely controlled.
