Ultrasonic imaging device and signal processing method

Abstract

To provide an ultrasound imaging apparatus capable of automatically and stably optimizing an imaging parameter for each examination even in a situation where an original ultrasound signal and electrical noise or the like are mixed in a reception signal, and shortening examination time.SOLUTION: A pilot ultrasound signal for detecting a feature of a subject is radiated from an ultrasound element to the subject. On the basis of a reception signal from the ultrasound element, a feature value is calculated which is a value representing a mode of distribution in a depth direction of the subject or an energy value at a specific depth of energy of the pilot ultrasound signal. A predetermined parameter value is determined on the basis of the feature value. An imaging signal is transmitted to one or more ultrasound elements, and an imaging ultrasound signal is radiated from the ultrasound element to the subject. A reception signal that is output by the ultrasound element receiving the imaging ultrasound signal reflected by the subject is processed using the parameter value to generate an image.SELECTED DRAWING: Figure 2
