A multi-planar reconstruction (MPR) technique based on the endoscope tip tracking information for MR-endoscope system is proposed. Cross sectional images of arbitrarily extracted sagittal, coronal, axial and oblique planes are readily reconstructed from the MR volume data according to the endoscope tip location and orientation detected by a gradient magnetic field sensor. The geometry data are annotated in the endoscope images as a digital watermark. The proposed technique enables smooth presentation of the region of interest in the MR images simultaneously superimposed on the endoscope images during operation.
