A system for producing a motion picture representing the movement of muscle lining a body channel includes a probe to be inserted in the channel, and a control unit to receive ultrasonic energy from the probe. More specifically, the probe has a transceiver capable of transmitting ultrasonic energy toward the muscle when within the body channel. The transmitted ultrasonic energy has a focal length to primarily focus on the muscle. The transmitted ultrasonic energy produces reflected ultrasonic energy (from the muscle) that the transceiver is capable of receiving. The control unit, which is in communication with the probe to receive the reflected ultrasonic energy, is capable of producing a motion picture signal representing the movement of the muscle. The motion picture signal is based on the reflected ultrasonic energy.
