Abstract
A multimodality image fusion and localisation system for radiosurgery treatments of arteriovenous malformations (AVM) has been developed and validated. Within this system, three-dimensional magnetic resonance angiography (MRA) and two-dimensional digital subtraction angiography (DSA) vasculature information is combined with three-dimensional magnetic resonance (MR) and/or computed tomography (CT) anatomical information in order to benefit from the functionality of all modalities. MRA/MR/CT datasets are fused, and linked to the DSA images. The consistency of the linking procedure is verified by correlation of the DSA images with two-dimensional ray-traced projections of the MRA datasets. Organ contours are drawn on the MRA images, simultaneously visualised on their MR/CT counterparts, and projected onto the DSA images for visual feedback. This procedure allows users to incorporate both vascular and anatomical information in the three-dimensional target localisation and delineation process. Patient examples illustrating the utility of the system are presented.
