Comparison of Two Protocols of Optimization of X Ray Radiations in Pediatric Interventional Neuroradiology
Comparison of Two Protocols of Optimization of X Ray Radiations in Pediatric Interventional Neuroradiology
Interventional Neuroradiology replaces surgery. This technology requires various exposition
 to X rays : number of X rays photographs, radioscopy, distance between patient and detector,
 speed of acquisition of X-rays photographs, high tension and intensity.

 The manipulator must find the right balance between quality of photographs and dose delivered
 to the patient (optimization).

 Children are particularly exposed to these risks of irradiation (sensitivity to X-rays and
 long life expectancy with risks. So, it is fundamental to optimize the dose delivered during
 the procedures.

 The investigators propose to analyse a study comparing two protocols of optimization of
 doses. The investigators' hypothesis is that the protocol experimented in this trial allows
 less radiation of the children, compared to the usual protocol.
