ABSTRACT:
An objective optical system is provided at a tip end portion of an insertion portion of an endoscope. A plurality of markers capable of transmitting an electromagnetic wave is placed at a target portion in an affected area. Each of the plurality of markers is adapted to transmit at least an information for defining the three-dimensional coordinates of the shape of the target area. At the rear end or the tip end portion of the insertion portion of the endoscope, a sensor is provided for electromagnetically detecting the information defining the three-dimensional coordinates of the shape of the target area and for determining the relative positional relation between the insertion portion and the three-dimensional coordinates of the shape of the target area.
