Abstract

Claims (20)

1. A method comprising:

transmitting a single unfocused ultrasound ping towards a tissue region of interest to insonify an entirety of the tissue region of interest with a transmit aperture comprising at least one transmit transducer element on an ultrasound transducer array;

receiving ultrasound echoes of the single unfocused ultrasound ping from the tissue region of interest with a plurality of receive transducer elements on the ultrasound transducer array;

forming a plurality of complete ultrasound images of the tissue region of interest corresponding to each of the plurality of receive transducer elements with the received ultrasound echoes of the single unfocused ultrasound ping; and

incoherently combining the plurality of complete ultrasound images.

2. The method of claim 1 further comprising accessing calibration data that describes a position and orientation of the at least one transmit transducer element and the plurality of receive transducer elements.

3. The method of claim 2 , wherein accessing calibration data comprises accessing a database that is remote from a control system of the ultrasound transducer array.

4. The method of claim 3 , wherein accessing calibration data comprises accessing an Internet-accessible database.

5. The method of claim 2 , wherein accessing calibration data comprises accessing data stored in a chip housed within a probe housing along with the array.

6. An ultrasound imaging system, comprising:

an ultrasound transducer array arranged to transmit and receive ultrasound energy into a tissue region of interest;

a transmit aperture comprising at least one transmit element in the ultrasound transducer array configured to insonify a scatterer in the region of interest with an unfocused ultrasound ping in the region of interest;

a receive aperture comprising a plurality of receive elements in the ultrasound transducer array configured to receive ultrasound echoes of the unfocused ultrasound ping from the scatterer; and

a control system in electronic communication with the ultrasound transducer array, the control system configured to control the transmit aperture to transmit a single unfocused ultrasound ping towards the tissue region of interest to insonify an entirety of the tissue region of interest, form a plurality of complete ultrasound images of the tissue region of interest corresponding to each of the plurality of receive transducer elements with the received ultrasound echoes of the single unfocused ultrasound ping, and incoherently combine the plurality of complete ultrasound images.

7. The system of claim 6 , wherein the control system is configured to access calibration data describing a position and orientation of each element of the transmit aperture and each element of the receive aperture.

8. The system of claim 7 , wherein the calibration data is stored in the control system.

9. The system of claim 7 , wherein the calibration data is stored remotely from the control system.

10. The system of claim 9 , wherein the calibration data is stored in an internet-accessible database.

11. The system of claim 7 , wherein the calibration data is stored in a chip housed within a probe housing along with the array.

12. The system of claim 6 wherein the ultrasound transducer array has a concave curvature about at least two axes.
