Interactive real-time MR image guided navigation for the intervention use is a promising strategy. However, it is difficult to perform complicated surgical procedures with the guidance of Real-time MR images only. Reformatted image from the pre-acquired high-resolution interoperative image volume is commonly used for improved visibility, with an assumption that no change of patient position during surgery, which is not always possible. Here we propose a method of full automatic motion compensation technique using tiny gradient tracking sensor (Endoscout) attached to the patient.
