Dose Load during Angiographic Procedures LCx Stenting

Abstract

The study of the dose load received by the personnel working with x-ray equipment is a very important task in the modern world. The purpose of this article is to assess the dose load based on published dosimetric measurements obtained by an interventional cardiologist from scattered X-ray during the angiographic procedure LCx stenting. The procedure is carried out under X-ray guidance using a Philips Allura Xper FD10 system. The dose calculations and assessments are made for three positions of the patient table—basic (zero), lowest and highest position, and for three control points—“Head”, “Gonads” and “Steps” where the dosimetric measurements of the received effective dose were performed. During the angiographic procedure, three different projections are used (RAO-caudal, LAO-caudal and Pure Cranial), each of which can be basic and the other two non-basic. In this regard, calculations have been made for each of them as a basic one. The results show that the dose load obtained from this procedure is mainly due to the work in the radiographic mode. To reduce the received dose it is necessary to take into account the position of the patient table at each projection, used as basic projection. To reduce the dose load on the body of the interventional cardiologist, it is important to wear appropriate individual radiation protection.
