Abstract
Introduction. During an ’Interventional Radiology (IR)’ procedure, the patient’s skin-dose may become very high for a burn, necrosis and ulceration to appear. In order to prevent these deterministic effects, an accurate calculation of the patient skin-dose mapping is essential. For most machines, the ’Dose Area Product (DAP)’ and fluoroscopy time are the only information available for the operator. These parameters have been shown to be a very poor indicator of the Peak Skin Dose. We developed a mathematical model that reconstructs the magnitude, shape, and localization of each irradation field on patient’s skin. In case of critical dose exceeding, the system generates warning alerts. The reconstruction is based on the geometric and dosimetric information provided by the DICOM files for each acquisition incidence. We present the results of its comparison with clinical studies.
