Abstract: An image captured by successive imaging over time by using a capsule endoscope is correlated with the imaging position and compiled into a database. The left side of a display screen of a monitor device displays a subject internal model, a trajectory path of the capsule endoscope, and a position mark indicating the imaging position. An image corresponding to the position of the position mark is displayed in an image display area on the right side. When a position mark on the trajectory path is designated by a mouse, the corresponding image is displayed. It is also possible to designate a section for which the image corresponding to the position mark is displayed or to designate a position mark where an unusual image is captured.

Abstract: An image processing apparatus performs image processing of a plurality of images taken by a medical instrument. The image processing apparatus includes an intracorporeal image determination unit that determines whether the image is an intracorporeal image obtained by photographing an inside of a body or not; and an intracorporeal image extraction unit that extracts the intracorporeal image based on a determination result by the intracorporeal image determination unit.

Abstract: Insertion of a probe comprising an array of 16 source coils through a forceps channel of an electronic endoscope prepares the source coils in the insert of electronic endoscope for use in monitoring work objects. To a bed where a patient lies, are mounted two sets of sensor coils crossing at a right angle to each other, each of which comprises at least four single core coils with a common central axis placed on the same line in the same direction. A control section of the system gives signals with radiofrequencies (driving signals) through source cables to the source coils, to excite the source coils to generate magnetic fields around them.
