Reduced radiation exposure in the cardiac catheterization laboratory with a novel vertical radiation shield

Abstract

Objectives: Investigation of novel vertical radiation shield (VRS) in reducing operator radiation exposure. Background: Radiation exposure to the operator remains an occupational health hazard in the cardiac catheterization laboratory (CCL). Methods: A mannequin simulating an operator was placed near a computational phantom, simulating a patient. Measurement of dose equivalent and Air Kerma located the angle with the highest radiation, followed by a common magnification (8 in.) and comparison of horizontal radiation absorbing pads (HRAP) with or without VRS with two different: CCL, phantoms, and dosimeters. Physician exposure was subsequently measured prospectively with or without VRS during clinical procedures. Results: Dose equivalent and Air Kerma to the mannequin was highest at left anterior oblique (LAO)-caudal angle (p
