Abstract:
Pediatric cardiac catheterization procedures have the potential to transmit high X-ray doses, which may lead to acute effects or latent skin reactions. Direct measurement of radiation dose was facilitated using nanodot dosimeters and radiochromic film. Direct measurement results were compared with vendor-listed dosimetry and calculation using phantom data. Vendor-listed data demonstrated a wide discrepancy with measured data, whereas the calculation reproducibly overestimated the actual dose. A simple formula was derived to calculate the dose using fluoroscopy time, cine frame quantity and average cine mA in a biplane environment.

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...
