摘要: In one embodiment, an ultrasound imaging assembly (80) includes a housing (82) having longitudinal axis (88), proximal end (86), and distal ending (84) defining receptacle (90). The transducer package (60) central (62) surface (66) positioned at desired angle (106) relative to the axis. is least partially disposed within so that generally perpendicular Such configuration permits relatively large percentage of signal pass through sheath (120) surrounding reduces assembly-to-assembly variations.
