Title:
ULTRASONIC PROBE
Document Type and Number:
WIPO Patent Application WO/2021/011220
Kind Code:
A3
Abstract:
An ultrasonic probe that comprises an ultrasonic transducer that includes an array of transducer elements and an attenuation material is provided. The attenuation material comprises a polymer composition that includes a liquid crystalline polymer and a thermally conductive particulate material. The liquid crystalline polymer has a melting temperature of about 270°C or more and a melt viscosity of about 500 Pa-s or less as determined at a temperature of 45°C above the melting temperature and shear rate of 400 s-1 in accordance with ISO Test No. 11443:2005, and the polymer composition also has a through-plane conductivity of about 0.2 W/m-K or more.
