Abstract

Objective: The effective radiation dose in diagnostic and interventional catheter investigations is difficult to compare in patients with congenital heart defects. This is caused by a high variability in patient size and weight, different angles, the use of monoplane or biplane equipment, the change in fluoroscopy only and image acquisition, and finally different frame rates used for image acquisition. Usually total fluoroscopy times and dose area products are used to provide some information and comparability, a standardized model however that enables a comparison between different X-ray devices is missing.
