Abstract

A wireless ultrasound probe has a probe case enclosing a transducer array, an acquisition circuit, a transceiver and a battery. The probe also includes a loudspeaker which produces audible sounds during use of the probe. The loudspeaker, which may be a piezoelectric loudspeaker, issues an alert when battery power is low or signal strength of the wireless transmission is poor or nonexistent. The loudspeaker can provide user feedback to the actuation of a button or control on the probe. The loudspeaker can provide haptic feedback during use of the probe, and can be used to produce audio Doppler tones or heart sounds during probe use.

Claims

1. A wireless ultrasound probe which transmits image data wirelessly to a host system comprising:

an array transducer;

an acquisition circuit coupled to the array transducer;

a transceiver coupled to the acquisition circuit which acts to wirelessly transmit image information signals to the host system;

a battery which operates to provide energizing potential to the array transducer, the acquisition circuit, and the transceiver;

a probe case housing the array transducer, acquisition circuit, transceiver and battery; and

a loudspeaker which acts to issue an audible tone during use of the probe,

wherein the loudspeaker is further operable to issue an audible tone when the transceiver signal strength is poor.

2. The wireless ultrasound probe of claim 1, wherein the loudspeaker is located in the probe case.

3. The wireless ultrasound probe of claim 1, wherein the loudspeaker is located on the host system.

4. The wireless ultrasound probe of claim 1, wherein the loudspeaker is further operable to issue an audible tone when the battery energy is low.

6. The wireless ultrasound probe of claim 1, wherein the loudspeaker is further operable to issue an audible tone when the strength of the signal transmitted by the transceiver and received by the host system is poor.

7. The wireless ultrasound probe of claim 1, wherein the wireless probe further includes a user control,

wherein the loudspeaker to produce an audible sound when the user control is actuated.

8. The wireless ultrasound probe of claim 1, further comprising a Doppler processor operable to produce audio Doppler signals in response to the reception of ultrasound echo signals,

wherein the array transducer is operable to receive ultrasound echo signals suitable for generating Doppler signals;

and

wherein the loudspeaker is responsive to the production of audio Doppler signals for producing audio Doppler sounds.

9. The wireless ultrasound probe of claim 1, wherein the array transducer is operable to receive heart sound signals;

and

wherein the loudspeaker is responsive to the reception of heart sound signals for producing audible heart sounds.

10. The wireless ultrasound probe of claim 1, wherein the loudspeaker further comprises a piezoelectric loudspeaker.

11. The wireless ultrasound probe of claim 10, wherein the piezoelectric loudspeaker is located behind a liquid-tight membrane.

12. The wireless ultrasound probe of claim 11, wherein the membrane is located in a wall of the probe case.
