Abstract

A method and system for acquiring data in an ultrasound system are provided. A transducer is operatively connected to a transmit beamformer and a receive beamformer. The receive beamformer is configured to obtain a first value associated with a fundamental frequency interleaved with a second value associated with a harmonic frequency. A first transmit signal is transmitted at a first frequency. A first echo signal is received in response to the first transmit signal. At least the first value associated with the first frequency is obtained from the first echo signal. An interleaved second transmit signal is transmitted at the first frequency or a second frequency. A second echo signal is received in response to the second transmit signal. At least the second value associated with a third frequency is obtained from the second echo signal. Images are generated and displayed based on the at least one first value and the at least one second value.

Claims

1. A method of configuring data acquisition in an ultrasound system, the method comprising the acts of:

(a) selecting a first image mode from the group of;

B-mode and M-mode;

(b) selecting a harmonic frequency from a list of at least the harmonic and at least one fundamental frequencies, said harmonic frequency associated with said first image mode, and said selection corresponding to selection of;

(i) transmission at a first center frequency;

(ii) reception of a first echo signal in response to said step (b)(i); and

(iii) obtaining from said first echo signal at least one first value associated with a center frequency that is a harmonic of the first center frequency;

(c) selecting a second image mode comprising a Doppler image mode;

(d) selecting a second center frequency associated with said second image mode, said selection corresponding to selection of;

(i) transmission at the second center frequency;

(ii) reception of a second echo signal in response to said step (d)(i); and

(iii) obtaining from said second echo signal at least one second value associated with the second center frequency; and

(e) displaying said at least one second value in a first region of a display and said at least one first value in a second region of said display.

2. The method of claim 1 wherein (a) comprises:

(a1) connecting a selected transducer to said system; and

(a2) defaulting said first image mode to a B-mode image in response to (a1).

3. The method of claim 1 wherein (b) comprises selecting using a key.

4. The method of claim 3 wherein (d) comprises selecting said second center frequency from a second list of frequencies using said key.

5. The method of claim 3 wherein (d) comprises selecting said second center frequency from a second list of frequencies using a second key.

6. The method of claim 3 wherein (b) and (d) comprise selecting with said key and a second key, said key associated with at least the harmonic frequency and said second key associated with the at least one fundamental frequency.

7. The method of claim 1 wherein (b) and (d) comprise selecting a combination of said harmonic frequency and said second center frequency with a single key.

8. The method of claim 1 wherein (c) comprises pressing a key.
