Possibilities of the patient’s and cardiologist’s X-ray dose reduction in interventional cardiology

The study provides an overview of possibilities of X-ray dose reduction in interventional cardiology both to patients and physicians.

The main source of physicians’ irradiation is the scatter radiation from patients, therefore the main way of the dose reduction is based

on the reduction of X-ray dose to patients. In the first part of the study, the principle of the automatic dose rate control, which controls

the amount of produced X-ray, is described. Further, an influence of the additional filtration, projection angle, magnification and frame

rate (pulse rate) on the resulting dose is explained. The second part deals with the influence of the projection angle and lead shielding

on the physicians’ dose.

Keywords: interventional cardiology, angiography system, X-ray dose reduction
