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.
