Abstract
A shape-of-endoscope detecting apparatus generally includes a shape detection unit, a marker, a marker locator unit, and a display control unit. The shape detection unit detects the shape of a portion of an insertion unit of an endoscope inserted into a subject, and produces graphic data expressing the shape thereof. The marker is placed near a position on the subject at which the endoscope is inserted. The marker locator unit acquires the location information of the marker. The display control unit graphically indicates on a display device the shape of the portion inserted into a body cavity, which is detected by the shape detection unit, using as a reference point the location information of the marker acquired by the marker locator. A shape-of-endoscope detecting method generally includes the steps of placing a marker, locating the marker, detecting the shape of the position of an endoscope inserted into a subject, and controlling the display of the detected shape.
