Lama Hadid-Beurrier, medical physicist at AP-HP provided this testimony and the first results of the study for calculating Peak Skin Dose in interventional radiology.

Calculation of Peak Skin Dose in interventional radiology : A scientific study conducted in the following healthcare institutions of the AP-HP (Paris’ Hospitals) group: Jean-Verdier, Kremlin-Bicêtre, Lariboisière, and Necker Enfants-Malades. Here are the firsts results.

“In interventional radiology, the assessment of the maximum cutaneous dose for the most irradiating activities and the patients most at risk is recommended by the French National Authority for Health (HAS) and the French Nuclear Safety (ASN) authority,” Lama Hadid-Beurrier explains. “A validation of the Radiation Dose Monitor (RDM) skin dose calculation module was performed using gafchromics films on two fixed interventional rooms of different brands. Configurations of increasing complexity have been reproduced on a PMMA phantom, and the first results obtained are very satisfactory. Indeed, RDM makes it possible to map the dose to the skin, taking into account all the incidences of the beams and the backscattered radiation of the patient, as well as the attenuation of the table and the mattress. A very good result (<27%) was obtained between the maximum cutaneous dose measured by the film and calculated by RDM. In addition, the skin dose maps obtained with a resolution of 1 cm², are faithful to the shapes as well as the actual dimensions of the fields observed on gafchromic films."
