Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The procedures of Interventional Cardiology are realized under exposure in the X-rays which can be sometimes important for the patient according to the nature of the procedure.

The estimation of the dose in the skin following a procedure of interventional cardiology is difficult. The knowledge of this dose allows to anticipate the appearance of determinist effects, and so to activate a dermatological follow-up of the exposed patient in case of overtaking of a dose threshold. Unfortunately, it is impossible to measure it directly and the thresholds of exposures are fixed from the measure of the kerma in the air accumulated at the exit of the tube with X-ray, what remains very indistinct.

Since a few years the manufacturers propose tools allowing an estimation of the dose the skin of the patient. The DoseMap software ® allows to consider this dose from the data of exposure supplied by the system. To do it, it uses a modelling simplified of the patient to feign the deposit of dose in the latter.

It seems to us interesting to verify the precision of this simulation by comparing it with a measure of the in vivo dose.
