An acoustic damping structure for use in an ultrasound transducer

摘要

An acoustic damping structure for use in an ultrasound transducer comprises a layer of acoustic damping material having an upper surface and a lower surface. A plurality of electrical conductors extend from the upper surface through the layer of acoustic damping material to the lower surface. The conductors each meet the lower surface of the damping structure at a position that is laterally offset from the position at which they meet the upper surface. The conductors follow paths with bends therein, for example the conductors are cranked. The conductors have a first portion extending from the upper surface into the acoustic damping layer, a second portion offset therefrom and extending from the lower surface into the acoustic damping layer, and a third portion extending within the acoustic damping layer from the first portion to the second portion.
