Abstract

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.

Claims

1. A system for producing a motion picture representing the movement of muscle lining a body channel, the system comprising:

a probe having a transceiver capable of transmitting ultrasonic energy toward the muscle when within the body channel, the transmitted ultrasonic energy having a focal zone to primarily focus on a pre-specified layer of the muscle, the transmitted ultrasonic energy producing reflected ultrasonic energy from the muscle, the transceiver being capable of receiving the reflected energy; and

a control unit in communication with the probe to receive the reflected ultrasonic energy, the control unit being capable of producing a motion picture signal representing the movement of the muscle, the motion picture signal being based on the reflected ultrasonic energy.

2. The system as defined by claim 1 wherein the transceiver includes a portion capable of receiving the reflected energy, the transceiver also including a portion capable of transmitting the ultrasonic energy toward the muscle.

3. The system as defined by claim 1 wherein the reflected energy comprises low velocity and high velocity signals, further wherein the control unit includes a low pass filter for filtering out the high velocity signals, the low velocity signals being no greater than about two centimeters per second.

4. The system as defined by claim 1 wherein the transceiver transmits ultrasonic energy having frequencies of between about 12 and 20 megahertz.

5. The system as defined by claim 1 wherein the probe further includes a medium container through which the ultrasonic energy is transmitted.

6. The system as defined by claim 1 wherein at least a portion of the transmitted ultrasonic energy has a focal length of no greater than about two centimeters.

7. The system as defined by claim 1 wherein the control unit includes an output for delivering the motion picture signals.

8. The system as defined by claim 1 wherein the channel includes one of the gastrointestinal tract and the genitourinary tract.

9. An apparatus for producing a motion picture signal representing the movement of muscle lining a body channel, the body channel having a probe inserted therein to capture images of the movement, the apparatus comprising:

a signal generator for producing an output signal causing the probe to output an initial ultrasound signal with a given frequency, the given frequency providing a focal zone for primarily focusing the initial ultrasound signal on a pre-specified layer of the muscle when the probe is within the body channel;

an output operatively coupled with the signal generator, the output capable of delivering the output signal to the probe;

a receiver capable of receiving a reflected ultrasonic signal from the probe, the reflected ultrasonic signal being produced by the initial ultrasonic signal reflecting from the muscle; and

a motion picture module operatively coupled with the receiver, the motion picture module capable of producing the motion picture signal representing the movement of the muscle, the motion picture being produced based on the reflected ultrasonic signal.

10. The apparatus as defined by claim 9 further including a low pass filter operatively coupled with the receiver, the low pass filter being capable of filtering out high velocity signals.

11. The apparatus as defined by claim 9 further including an amplifier operatively coupled to the receiver, the amplifier being capable of amplifying the reflected ultrasonic signal.

12. The apparatus as defined by claim 9 further comprising a motion picture port operatively coupled with the motion picture module, the motion picture port being capable of transmitting the motion picture signal.

13. The apparatus as defined by claim 9 further comprising a control unit that controls qualities of the output ultrasound energy.

14. The apparatus as defined by claim 9 wherein the given frequency is between about 12 and 30 megahertz.

15. The apparatus as defined by claim 9 wherein the channel is one of the gastrointestinal tract and the genitourinary tract.

16. A computer program product for use on a computer system for producing a motion picture signal representing the movement of muscle lining a body channel, the body channel having a probe inserted therein to capture images of the movement, the computer program product comprising a computer usable medium having computer readable program code thereon, the computer readable program code comprising:

program code for producing an output signal causing the probe to output an initial ultrasound signal with a given frequency, the given frequency providing a focal zone for primarily focusing the initial ultrasound signal on the muscle when the probe is within the body channel;

program code for delivering the output signal to the probe;

program code for receiving a reflected ultrasonic signal from the probe, the reflected ultrasonic signal being produced by the initial ultrasonic signal reflecting from the muscle; and

program code for producing the motion picture signal representing the movement of the muscle, the motion picture being produced based on the reflected ultrasonic signal.

17. The computer program product as defined by claim 16 further including program code for filtering out high velocity signals.

18. The computer program product as defined by claim 16 further including program code for amplifying the reflected ultrasonic signal.

19. The computer program product as defined by claim 16 further comprising program code for transmitting the motion picture signal.

20. The computer program product as defined by claim 16 wherein at least a portion of the initial ultrasonic energy has a focal length of no greater than about five centimeters.

21. The computer program product as defined by claim 16 wherein the given frequency is between about 12 and 20 megahertz.

22. The computer program product as defined by claim 16 wherein the channel is one of the gastrointestinal tract and the genitourinary tract.
