Document Type and Number:
WIPO Patent Application WO/2015/093259
Kind Code:
A1
Abstract:
Provided are an ultrasound probe, an element circuit thereof, and an ultrasound diagnostic device, whereby high image quality is possible and reduced size and lower cost are made possible. Provided is an ultrasound probe, comprising: a 2-D array oscillator wherein a plurality of oscillators are arrayed two-dimensionally; and a 2-D array IC in which are formed, upon an IC substrate, drive circuits which are disposed upon each of the oscillators of the 2-D array oscillator to drive each of the oscillators at different timings with a prescribed delay quantity, and common current sources which supply drive current to the oscillators of the 2-D array oscillator. The number n of the common current sources which are formed upon the IC substrate is fewer than the number N of the drive circuits which are formed upon the IC substrate.
