ABSTRACT:
A position and orientation state pickup is designed to detect the position and orientation state of an endoscope inserted into a living body without any adverse effect on the living body, which is often observed in X-ray analysis. The position and orientation state pickup, generating an electro-magnetic field with frequency at least lower than the visible ray range toward the body from outside; detects influence of the endoscope inserted into the body on two-dimensional energy distribution of the electro-magnetic field generated toward the body; and show the position and orientation state of the endoscope from the detection results.
