|Abstract: ||Computed tomography (CT) fluoroscopy is able to give real time images to a physician undertaking minimally
invasive procedures such as biopsies, percutaneous drainage, and radio frequency ablation (RFA). Both operators
executing the procedure and patients too, are thus at risk of radiation exposure during a CT fluoroscopy.
This study focuses on the radiation exposure present during a series of radio frequency ablation (RFA) procedures,
and used Gafchromic film (Type XR-QA; International Specialty Products, USA) and thermoluminescent dosimeters
(TLD-100H; Bicron, USA) to measure the radiation received by patients undergoing treatment, and also operators
subject to scatter radiation.
The voltage was held constant at 120 kVp and the current 70mA, with 5mm thickness. The duration of irradiation
was between 150-638 seconds.
Ultimately, from a sample of 30 liver that have undergone RFA, the study revealed that the operator received the
highest dose at the hands, which was followed by the eyes and thyroid, while secondary staff dosage was moderately
uniform across all parts of the body that were measured. © 2010 Biomedical Imaging and Intervention Journal. All
