Abstract

In one aspect, an enhanced ultrasound device may generally comprise an ultrasound probe including a housing and at least one transducer element disposed within the housing. The ultrasound probe may be configured to generate ultrasound image signals associated with an object being imaged. In addition, the device may include an acoustic receiver associated with the ultrasound probe. The acoustic receiver may be configured to generate auscultation signals associated with sounds generated by the object as the object is being imaged using the ultrasound probe.

Claims

1. A system for conducting auscultatory ultrasounds, the system comprising:

an ultrasound probe including a housing having a detection end defining a contact surface, the ultrasound probe further including at least one transducer element and a backing disposed within the housing, the backing being configured to reduce back reflections associated with the ultrasound probe and being positioned within the housing such that the at least one transducer element is disposed between the backing and the contact surface, the at least one transducer element being configured to transmit transducer-generated ultrasound waves towards an object being imaged and receive reflected ultrasound waves corresponding to the transducer-generated ultrasound waves as reflected off of the object being imaged, the ultrasound probe being configured to generate ultrasound image signals based on the reflected ultrasound waves received by the at least one transducer element;

an acoustic receiver positioned within the housing, the acoustic receiver including a sensing end configured to receive object-generated sound waves originating from the object being imaged, the acoustic receiver being positioned adjacent to the at least one transducer element within the housing such that the sensing end of the acoustic receiver is positioned at a location between the contact surface and the backing, the object-generated sound waves differing from the transducer-generated ultrasound waves and the reflected ultrasound waves, the object-generated sound waves being associated with sounds generated by the object as the object is being imaged using the at least one transducer element, the acoustic receiver being further configured to generate auscultation signals based on the received object-generated sound waves; and

a computing device communicatively coupled to the ultrasound probe and the acoustic receiver, the computing device being configured to combine the ultrasound image signals and the auscultation signals to produce an auscultatory ultrasound image,

wherein the auscultatory ultrasound image corresponds to a synchronization of the sounds generated by the object with a moving ultrasound image produced based on the ultrasound image signals.

2. The system of claim 1, wherein the acoustic receiver comprises a unidirectional microphone.

3. The system of claim 1, further comprising a display and a speaker communicatively coupled to the computing device, the computing device being configured to transmit signals associated with the auscultatory ultrasound image to the display and the speaker for broadcasting auscultatory ultrasound image.

4. The system of claim 1, wherein the object comprises an internal organ.

12. The system of claim 1, wherein the acoustic receiver corresponds to a separate receiver than a receiver of the at least one transducer element.

5. An enhanced ultrasound device, comprising:

an ultrasound probe including a housing having a detection end defining a contact surface, the ultrasound probe further including at least one transducer element and a backing disposed within the housing, the backing being configured to reduce back reflections associated with the ultrasound probe and being positioned within the housing such that the at least one transducer element is disposed between the backing and the contact surface, the at least one transducer element being configured to transmit transducer-generated ultrasound waves towards an object being imaged and receive reflected ultrasound waves corresponding to the transducer-generated ultrasound waves as reflected off of the object being imaged, the ultrasound probe being configured to generate ultrasound image signals based on the reflected ultrasound waves received by the at least one transducer element; and

an acoustic receiver positioned within the housing, the acoustic receiver including a sensing end configured to receive object-generated sound waves originating from the object being imaged, the acoustic receiver being positioned adjacent to the at least one transducer element within the housing such that the sensing end of the acoustic receiver is positioned at a location between the contact surface and the backing, the object-generated sound waves differing from the transducer-generated ultrasound waves and the reflected ultrasound waves, the object-generated sound waves being associated with sounds generated by the object as the object is being imaged using the at least one transducer element, the acoustic receiver being further configured to generate auscultation signals based on the received object-generated sound waves.

6. The enhanced ultrasound device of claim 5, wherein the acoustic receiver comprises a unidirectional microphone.

7. The enhanced ultrasound device of claim 5, wherein the ultrasound probe and the unidirectional acoustic receiver are configured to be communicatively coupled to a computing device, the computing device being configured to combine the Ultrasound image signals and the auscultation signals to produce an auscultatory ultrasound image.

8. The enhanced ultrasound device of claim 7, wherein the auscultatory ultrasound image comprises a synchronization of the sounds generated by the object with a moving ultrasound image produced based on the ultrasound image signals.

9. The enhanced ultrasound device of claim 7, wherein the object comprises an internal organ.

13. The enhanced ultrasound device of claim 5, wherein the acoustic receiver corresponds to a separate receiver than a receiver of the at least one transducer element.

10. A method for conducting auscultatory ultrasounds, the method comprising:

receiving, with a computing device, ultrasound image signals generated by an ultrasound probe including a housing having a detection end defining a contact surface, the ultrasound probe further including at least one transducer element and a backing disposed within the housing, the backing being configured to reduce back reflections associated with the ultrasound probe and being positioned within the housing such that the at least one transducer element is disposed between the backing and the contact surface, the at least one transducer element being configured to transmit transducer-generated ultrasound waves towards an object being imaged and to receive reflected ultrasound waves corresponding to the transducer-generated ultrasound waves as reflected off of the object being imaged, the ultrasound probe being configured to generate the ultrasound image signals based on the reflected ultrasound waves received by the at least one transducer element;
