摘要： An acoustic backing element includes a glass fiber epoxy composite planar substrate to the outer major surfaces of which are applied electrically conductive material. The electrically conductive material may be a conductive layer that is etched to expose electrical contact material in the form of conductive traces. Each conductive trace provides electrical connection between a transducer element and electrical control circuitry typically located on an electrical circuit board. The acoustic backing element provides precisely located electrical contacts for connecting the transducer elements to their control circuitry, while simultaneously providing superior acoustic attenuation. In addition, the thermal coefficient of expansion (TCE) of the glass fiber epoxy composite material comprising the planar substrate can be closely matched to the TCE of the electrical contact material. In this manner, fatigue and failure caused by mechanical stresses between the planar substrate and the electrical contact material due to temperature extremes and temperature cycling are significantly reduced.
摘要翻译： 声学背衬元件包括玻璃纤维环氧复合材料平面基底，其外主表面被施加导电材料。 导电材料可以是导电层，其被蚀刻以以导电迹线的形式暴露电接触材料。 每个导电迹线提供换能器元件和通常位于电路板上的电控制电路之间的电连接。 声学背衬元件提供精确定位的电触点，用于将换能器元件连接到其控制电路，同时提供优异的声衰减。 此外，包括平面基板的玻璃纤维环氧复合材料的热膨胀系数（TCE）可以与电接触材料的TCE紧密匹配。 以这种方式，由于温度极限和温度循环，平面基板和电接触材料之间的机械应力引起的疲劳和故障显着降低。

摘要： A biopsy needle guide in accordance with the invention is configured for attachment to an ultrasound transducer. The biopsy needle guide is arranged in two sections, an inner attachment block and an outer attachment block. The inner attachment block includes (i) a coupler which attaches the inner attachment block to the ultrasound transducer and (ii) a first engagement structure which extends from a surface thereof. The outer attachment block includes a biopsy needle guide through hole and a second engagement structure. The second engagement structure releasably mates with the first engagement structure even when the inner attachment block is covered by a sterile film sheath.
