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

Dans un mode de réalisation, un ensemble d'imagerie à ultrasons (80) comprend un boîtier (82) présentant un axe longitudinal (88), une extrémité proximale (86) et une extrémité distale (84) définissant un réceptacle (90). Cet ensemble d'imagerie comporte un détecteur (60) possédant un axe médian (62) et une surface d'imagerie (66) placée selon un angle désiré (106) par rapport à l'axe médian. Ce détecteur est situé au moins partiellement à l'intérieur du réceptacle, de sorte que l'axe médian est généralement perpendiculaire à l'axe longitudinal. Cette configuration permet à un pourcentage relativement important du signal ultrasonore de passer à travers une gaine (120) entourant l'ensemble d'imagerie et limite les variations d'ensemble à ensemble.
