Abstract:
An Online Survey among Interventional Cardiologists (IC) assessed the knowledge (five questions) and practice of radiation safety (eleven questions). Out of 185 respondents, knowledge of annual radiation dose (2% knew), LAO cranial view giving maximum radiation (48%) and benefit of assessment of radiation exposure with dose area product (31%) was limited. Radiation safety was practiced "whenever I remember" in 37-59%. Radiation safety practices were optimal frame rate selection (32%), distancing from x-ray unit (17%), collimation use (30%), positioning the image detector close to chest (91%) and personal dosimeters use (40%). A major gap exists between knowledge and practice of radiation safety.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
