摘要： First and second ultrasonic transducers are provided at the distal end portion of a flexible insertion portion (to serve as a probe) of an endoscope. During diagnosis, the distal end portion of insertion portion is fixed in a tubular organ by a balloon which is filled with water. Ultrasonic lenses having different focal distances are mounted on the transducers. The resonance frequencies of the transducers differ from each other. The transducers are rotated about a shaft of the insertion portion by a motor, in order to mechanically radial-scan an object to be examined. A relay box for supplying a drive signal to the transducers is connected to the endoscope, and a diagnositc device with a display is connected to the relay box. The relay box includes first and second transmitting circuits, and output drive pulses therefrom are supplied to the transducers. The relay box also comprises a switch and a switching circuit connected to the transmitting circuits for selecting one of the transmitting circuits by operating the switch. Therefore, only a selected one of the transmitting circuits supplies the drive pulse to the transducer. An ultrasonic echo signal received by the transducer is supplied to the diagnostic device to display a tomographic image.

摘要： First and second ultrasonic transducers having the same resonance frequency are provided at the distal end portion of an endoscope. Ultrasonic lenses having different focal lengths are mounted on first and second transducers, respectively. First and second transducers are rotated around the axis of the insertion portion and mechanically radial-scan an object to be examined. A controller supplies timing signals for driving the transducers in response to the radial-scan to a diagnostic device. The diagnostic device supplies drive pulses synchronized with the timing signals to either of first and second transducers. Ultrasonic echo signals received by first and second transducers are converted into reception signals and input to the diagnostic device. The diagnostic device synthesizes only those signals among the reception signals falling within predetermined distance ranges including focal points to form a tomographic image of the object.
