Document Type and Number:
WIPO Patent Application WO/2014/069697
Kind Code:
A1
Abstract:
A probe having a plurality of acoustic paths is disclosed. The disclosed probe comprises: a housing: a piezoelectric material which is attached to the inside of the housing and generates an ultrasound signal by a piezoelectric effect; a matching layer which has a plurality of layers for gradually reducing an acoustic impedance difference between the piezoelectric material and an inspected object; a probe lens which allows the ultrasound signal to be focused on a spot at which the inspected object is positioned, and which receives an ultrasound echo signal reflected from the inspected object; and a cable for transmitting the ultrasound echo signal to a body, wherein the matching layer has a structure with a plurality of acoustic paths by the plurality of layers.
