Selection of electronic equipment for digital X-ray diagnostic scanners

Abstract

615.471.03:616-073.75 X-Ray diagnostic systems with digital image processing are presently extensively developed and manufactured worldwide.The physical principles underlying digital X-ray imaging may differ in different X-ray diagnostic systems available from different manufacturers [1][2][3]. However, in any of these systems information is displayed on a video monitor screen and can be processed if necessary. The sites of interest can be selected, and linear dimensions can be measured. Both images and corresponding text information can be stored, archived, and printed. The goal of this work was to describe methodological approaches to rational selection of electronic equipment for digital X-ray imaging and data processing, archiving, storage, display, printing, etc. The study was focused mainly on scanning X-ray system for prophylactic examination of lungs, because these systems could provide the opportunity for solving an urgent problem of diagnosis of tuberculosis.The solution of this problem should be based not only on purely technological but also on economic factors (availability of certain equipment for health service organizations). However, technical aspects (performance of monitors, printers, memory units, etc.) should be of primary concern.Spatial resolution is one of the most important characteristics of X-ray diagnostic devices. The limiting value of spatial resolution is determined by the following equation:
