METHOD AND APPARATUS FOR APERTURE SELECTION IN ULTRASOUND IMAGING
First Claim
1. A method for controlling an ultrasound imaging system, said method comprising:
- defining a sample volume gate on a two-dimensional (2D) ultrasound image, the sample volume gate defining a location at which flow is to be estimated;
automatically calculating a first signal-to-noise (SNR) with an initial aperture size and position;
automatically calculating a second SNR with a different aperture size and or position;
automatically comparing the first SNR with the first aperture to the second SNR with the second aperture;
automatically adjusting the steering angle and aperture size for the transmit and receive beams of an ultrasound probe based on the comparison.

Abstract
A method for controlling an ultrasound imaging system includes defining a sample volume gate on a two-dimensional (2D) ultrasound image, the sample volume gate defining a location at which flow is to be estimated, automatically calculating a SNR for an initial transmit and receive steering position (aperture location) and aperture size, automatically calculating a SNR for a different second transmit and receive steering position (aperture location) and aperture size, automatically comparing the SNR for the first set of apertures to the SNR for the second set of apertures, and automatically adjusting the steering angle and an aperture size of an ultrasound probe'"'"'s transmit and receive events based on the comparison.
