ABSTRACT:
Positioning of interventional devices within the patient image volume of an MRI system is performed while viewing real-time fluoroscopic MR images of such devices superimposed upon a saved prior image ("ghost") of patient anatomy that was earlier located within the same image volume. After such interventional medical procedure is thoroughly planned using the earlier acquired three-dimensional ghost image, the patient anatomy is relocated within the image volume and the final selected trajectory for the interventional device or medical procedure is then performed (preferably while real time MRI fluoroscopy is used to monitor the actual interventional procedure within the real patient anatomy).
