Ultrasound processing apparatus and method
First Claim
1. An ultrasound processing apparatus, comprising:
- a probe that includes a vibration generator, wherein the vibration generator is configured to vibrate the probe based on a vibration parameter;
a vibration controller configured to;
set the vibration parameter of the vibration generator;
receive a reflected signal from an object corresponding to an ultrasound signal, wherein the reflected signal is acquired by the probe;
estimate a strain of the object based on the reflected signal;
change, based on the strain, the vibration parameter to synchronize a timing of the vibration generated by the vibration generator and a timing of detection of the strain; and
a vibration driver configured to drive the vibration generator based on the vibration parameter.

Abstract
The present disclosure relates to an ultrasound processing apparatus and method, and a program that enable easy and stable measurement of tissue characteristics. A vibrator driving unit drives a vibrator incorporated in an ultrasound probe based on a vibration parameter from a vibrator control unit. The vibrator control unit supplies a vibration parameter that is set in accordance with an indication signal input via a user interface, distribution information of viscoelastic coefficients, which is a measurement result of strain computed by a strain computation unit, or the like, and controls the vibrator driving unit. The present disclosure can be applied to, for example, an ultrasound diagnostic imaging apparatus that generates an ultrasound image based on a signal from a probe that captures an ultrasound image, and displays the ultrasound image.
