Interkomparacijska mjerenja u oblasti ispitivanja rendgen-aparata

Abstract

U radu su prikazani rezultati interkomparacije dvije laboratorije iz oblasti ispitivanja rendgen-aparata u Crnoj Gori i Srbiji. Međulaboratorijsko poređenje se odnosi na mjernu opremu Barracuda RTI Elektonics sa MPD detektorom koja služi za ispitivanje rendgen uređaja na osnovu standardnih protokola za QC u dijagnostičkoj radiologiji. Osnovni zadatak interkomparacije bio je verifikacija tehničkih karakteristika mjernog aparata sa kojim se kontroliše niz parametara koji utiču na kvalitet rada rendgen- aparata. Interkomparacija se odnosi na mjerne veličine: napon rendgenske cijevi, jačina kerme u vazduhu i debljinu poluslabljenja (HVL). U radu je opisana metodologija i naćin organizacije interkomparacije a prikazani su i postignuti rezultati i zaključak.

Results of inter-comparison of two laboratories, dealing with examination of X-ray units in Montenegro and Serbia, have been presented in this work. Inter- laboratory comparison is related to measuring equipment Barracuda RTI Electronics with MPD detector, which is used for examination of X-ray units on the basis of standard protocols for QC in diagnostic radiology. Basic aim of inter-comparison was to verify technical characteristics of measuring apparatus, and they are used for control of numerous parameters which influence the quality of X-ray apparatus performance. Inter-comparison concerns the following measuring figures: voltage of X-ray tube, intensity of karma in air and the width of half-attenuation (HVL). Methodology and organization manner of inter-comparison have been described in this work, and reached results and conclusion have been presented as well. Measuring results of all parameters are comparable, even in the interval where measuring uncertainty exists.
