Title:
超音波プローブおよび超音波診断装置
Document Type and Number:
Japanese Patent JP4551524
Kind Code:
B2
Abstract:
An ultrasonic diagnosis apparatus has an ultrasonic probe having a plurality of arrayed transducer elements, a transmitting beam former for generating driving signals for driving transducer elements, and a receiving beam former for generating receiving signals based on echo signals received by transducer elements. The transmitting beam former generates driving signals so that phases of ultrasonic waves generated from transducer elements are aligned at multiple focal points. An image processor extracts harmonic components from receiving signals of ultrasonic waves having multiple focal points, and generates ultrasonic image data based on the harmonic components.
