    Abstract: A multi-focus probe (100) that includes a motor (250) communicatively coupled with a lead screw (254) and configured to turn the lead screw (254) about a lengthwise axis of the lead screw (254), wherein the lead screw (254) includes a length having threads. The probe (100) also includes a lead-screw nut (256) positioned about the lead screw (254) such that the lead-screw nut (256) engages the threads and such that the lead-screw nut (256) and the lead screw (254) can move relative to one another via the threads, a transducer (104) configured to move vertically with the lead screw (254), and an enclosure (106) surrounding the transducer (104), wherein the enclosure (106) includes a probe face (118) configured to hold fluid and engage a wave emission target such that waves from the transducer (104) can enter the target. Further, the probe (100) includes a capture feature (268) capable of engaging the lead-screw nut (256) such that the lead-screw nut (256) is vertically fixed relative to the probe face (118) and such that the lead screw (254) moves away from the probe face (118) when rotating within the lead-screw nut (256) in a first direction and moves toward the probe face (118) when rotating within the lead-screw nut (256) in a second direction opposite to the first direction while the lead-screw nut (256) is engaged by the capture feature (268).

    Abstract: Sonde échographique (10) comprenant un transducteur (17) comportant une barrette d'éléments transducteurs disposée d'une manière amovible dans une partie formant tête (12). Un ou plusieurs étage(s) de module(s) de circuits électroniques (19, 21) est/sont couplé(s) au transducteur (17) et est/sont agencé(s) pour exciter le transducteur (17). Une partie formant poignée (14) est assemblée d'une manière séparable avec la tête (12). La tête (12) et la poignée (14) sont disposées de manière à renfermer le/les étage(s) de module(s) de circuits électroniques (19, 21). La sonde échographique (10) sert dans des applications à une dimension, des applications à deux dimensions et des applications volumétriques.
