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.
