It allows the operator to watch both target lesion and current position simultaneously while planning ahead propagation very carefully. In the proposed method, MRI/CT scan is performed before the procedure,wherem patient carries fixed markers attached to body. The system allows accurate mapping of patient’s body in the procedure room, and relate it with respect to patient’s position in scanner. This allows patient to be freely and easily moved from scanner to operation table. It reduces scan significantly and also frees scanner. Accuracy of position is to within less than 3 mm at an update rate of less than 0.6 seconds.
