Title:
METHOD FOR PRODUCING INTRAVASCULAR ULTRASONIC TRANSDUCER AND STRUCTURE THEREOF
Document Type and Number:
WIPO Patent Application WO/2015/115779
Kind Code:
A1
Abstract:
The present invention relates to a method for producing an intravascular ultrasonic transducer and a structure for same, the method for producing a ultrasonic transducer producing a single element by: forming a piezoelectric element lapped according to a previously set thickness; depositing conductive material on the lapped surface of the piezoelectric element; forming a matched layer and a rear surface layer by casting the front and rear surfaces of the piezoelectric element to which conductive material has been deposited; lapping according to a previously set thickness; and dicing an element, which is a stack of a matched layer, a piezoelectric element and a rear surface layer, along the stack direction so that the size of the element is less than the critical size for intravascular ultrasound (IVUS).
