摘要：
An apparatus for providing efficient transmission of a beam of acoustic waves between an ultrasonic transducer (103) and a remotely located body under examination by the beam. The apparatus includes a housing (101) having an interior arranged so that the ultrasonic transducer (103) is disposed therein. A prism (105) is acoustically coupled with the transducer (103) and with an acoustic waveguide (107) having a longitudinal dimension extending outwardly from the interior of the housing (101). The acoustic prism (105) is fixedly coupled with a proximate portion of the waveguide (107) so as to provide efficient transmission of the beam of acoustic waves between the prism (105) and the waveguide (107). Accordingly, The beam of acoustic waves is transmitted from the transducer (103), through the prism (105), and along the longitudinal dimension of the waveguide, to a distal portion of the waveguide. The distal portion of the waveguide is inserted into a remotely located patient's body under examination. The distal portion of the waveguide emits the ultrasonic beam, scanning the tissue of interest.
摘要（中）：
一种用于在超声波换能器（103）和受光束检查的远位身体之间提供声波束的有效传输的装置。 该装置包括壳体（101），其具有布置成使得超声波换能器（103）设置在其中的内部。 棱镜（105）与换能器（103）声学耦合，并且具有从壳体（101）的内部向外延伸的纵向尺寸的声波导（107）。 声波棱镜（105）与波导（107）的近似部分固定地耦合，以便在棱镜（105）和波导（107）之间提供声波束的有效传输。 因此，声波束从换能器（103）通过棱镜（105）沿着波导的纵向尺寸传输到波导的远端部分。 波导的远端部分被插入到被检查的位于远处的患者体内。 波导的远端部分发射超声波束，扫描感兴趣的组织。
