title: Needle positioning in interventional MRI procedure: real time optical localisation and accordance with the roadmap.
abstract: This study presents a system designed to assist the surgeon during interventional procedures performed by Magnetic Resonance Imaging (MRI). In order to reach the target during guidance in a double obliquity trajectory, this system provides accurate information about both the entry point and the orientation of the needle.
