A system for Interventional MRI using Infrared tracking of a handeld needle guide was adapted for practical use in closed-bore scanners. This was achieved by mapping of the image space to a patient space with the table outside the scanner bore to permit delayed visualisation of the targeted site. This novel method enables manual intervention of complex sites to be handled with greater care than other methods, and provides a relatively low-cost option for MR-guided interventions.
