Abstract

The disclosed embodiments include a method, system, and device for conducting ultrasound interrogation of a medium. The novel method includes transmitting a non-beamformed or beamformed ultrasound wave into the medium, receiving more than one echoed ultrasound wave from the medium, and converting the received echoed ultrasound wave into digital data. The novel method may further transmit the digital data. In some embodiments, the transmitting may be wireless. The novel device may include transducer elements, an analog-to-digital converter in communication with the transducer elements, and a transmitter in communication with the analog-to-digital converter. The transducers may operate to convert a first electrical energy into an ultrasound wave. The first electrical energy may or may not be beamformed. The transducers also may convert an echoed ultrasound wave into a second electrical energy. The analog-to-digital converter may convert the electrical energy into digital data, and the transmitter may transmit the digital data.

Claims

1. A method for conducting ultrasound interrogation of a medium, comprising:

receiving at a handheld probe a plurality of non-beamformed ultrasound echo waves, the plurality of non-beamformed ultrasound echo waves produced by the transmission of non-beamformed ultrasound waves into the medium, wherein the receiving is performed at an acquisition frame rate of at least 17 frames per second;

converting the plurality of non-beamformed ultrasound echo waves to digital data at the handheld probe, the digital data representing the plurality of non-beamformed ultrasound echo waves;

arranging the digital data into a data stream at the handheld probe; and

wirelessly transmitting the data stream from the handheld probe, wherein the transmitting is performed at a transmission frame rate at least as fast as the acquisition frame rate.

2. The method of claim 1, wherein the digital data is arranged into data streams.

3. The method of claim 2, wherein the data streams comprise one or more channels of data.

4. The method of claim 1, wherein the arranging comprises transmitting the digital data over a plurality of multiple channels.

5. The method of claim 1, further comprising wirelessly receiving the digital data stream over wireless channels, wherein at least one wireless channel is in an orthogonal arrangement with respect to another wireless channel.

6. The method of claim 1, further comprising arranging the digital data using at least one of the following techniques:

manipulating the digital data after converting the received ultrasound echo wave to digital data or manipulating the received ultrasound echo waves prior to converting the received ultrasound echo wave to digital data.

7. The method of claim 1, wherein arranging the digital data comprises at least one of the following:

multiplexing or interleaving.

8. The method of claim 7, further comprising multiplexing using at least one of the following techniques:

time-division multiplexing, frequency-division multiplexing, code-division multiplexing, or pulse width-division multiplexing.

9. The method of claim 7, wherein the digital data is interleaved as a function of at least one of the following:

time, position of transducer channels, or data bit position.

10. The method of claim 1, further comprising dearranging the digital data stream back into the digital data signals.

11. A device for conducting ultrasound measurements of a medium, the device being a handheld probe, the device comprising:

a receiver for receiving a plurality of non-beamformed ultrasound echo waves at the handheld probe, the plurality of non-beamformed ultrasound echo waves produced by the transmission of non-beamformed ultrasound waves into the medium, wherein the receiver is configured to receive at an acquisition frame rate of at least 17 frames per second;

an analog-to-digital converter in communication with the receiver for converting the plurality of non-beamformed ultrasound echo waves to digital data in the handheld probe, the digital data representing the plurality of non-beamformed ultrasound echo waves;

a multiplexer in communication with the analog-to-digital converter for multiplexing the digital data into a data stream in the handheld probe; and

a transmitter in communication with the multiplexer for wirelessly transmitting the data stream from the handheld probe, the transmitter configured to transmit the data stream at a transmission frame rate at least as fast as the acquisition frame rate.

12. The device of claim 11, wherein the transmitter transmits over multiple wireless channels, and wherein at least one wireless channel is in an orthogonal arrangement with respect to another wireless channel.

13. The device of claim 11, wherein the multiplexer arranges the digital data into data streams.

14. The device of claim 13, wherein the data streams comprise one or more channels of data.

15. The device of claim 11, wherein the multiplexer multiplexes the digital data using at least one of the following techniques:

manipulating the digital data after converting the received ultrasound echo wave to digital data or manipulating the received ultrasound echo waves prior to converting the received ultrasound echo wave to digital data.

16. The device of claim 11, wherein the multiplexer multiplexes the digital data using at least one of the following techniques:

time-division multiplexing, frequency-division multiplexing, code-division multiplexing, or pulse width-division multiplexing.

17. The device of claim 11, further comprising a demultiplexer that dearranges the digital data stream back into the digital data signals.
