Abstract
A radioactive ray detecting endoscope comprises an elongated insertable part, an ultrasonic imaging apparatus provided in the tip part of the insertable part for transmitting ultrasonic waves toward an observed part, for receiving echoes from the observed part by these ultrasonic waves, and for outputting a signal for forming an ultrasonic image and a radioactive ray detecting apparatus arrangeable in the tip part of the insertable part for detecting radioactive rays. Preferably, the observing direction of the ultrasonic imaging apparatus and the detecting direction of the radioactive ray detecting apparatus substantially coincide with each other.
