Paper Abstract

MRI-guided interventional procedures are critically dependent on accurate localization of an MRI-compatible needle used as a guiding device for laser fiber optic therapy. We present a scheme which utilizes the 3D imaging capability of the MRI modality and the 3D image processing capability of computer workstations to automatically and time-efficiently localize and display the tip of the needle on an oblique plane which cuts through the scanned object.
