Abstract :
A new approach of registration in multimodal imaging has been developed. Modalities involved are digital subtracted angiography (DSA, 2D) and magnetic resonance angiography (MRA, 3D). Our approach is an hybrid one, mixing feature and intensity based approaches. This approach is based on the extraction of a anatomical referential common to both MRA and DSA. The results obtained prove the methods efficiency in a clinical context. This paper present the validation methodology to make it possible the replacement of the localization DSA examination by the diagnosis one, thus avoiding supplementary costs, lost time and medical hazards for the patient and for the medical staff
