The effect of the ceiling-mounted radiation shielding on the amount of the scatter radiation was assessed under conditions\nsimulating obese patients for clinically relevant exposure parameters. Measurements were performed in different projections and\nwith different positions of the ceiling-mounted shielding: without shielding; shielding closest to the patient; and shielding closest\nto the physician performing the procedure. The protection provided by the shielding was assessed for cardiology when the femoral\naccess is used and for radiology when the physician performs the procedure in the abdominal area. The results show that the use of\nthe ceiling-mounted shielding can decrease the dose from the scatter radiation by 95% at the position of the performing physician.\nIn cardiology, the impact is more pronounced when the left oblique projection is used. In radiology, a large decrease was observed\nfor right oblique projections, compared to cardiology.The ceiling-mounted shielding should be placed as close to the physician as\npossible.The idea of creating the largest radiation shadow by placing the radiation shielding as close to the patient as possible does\nnot provide as effective radiation protection of the operator as it might be thought.
