Abstract:
1. An ultrasonic probe which scans a volumetric region by movement of an array transducer comprising: a probe case with an end cap having a fluid compartment at a distal end; an array transducer mounted on a carriage assembly in the fluid compartment; a pair of rails on which the carriage assembly travels in the fluid compartment; a pair of rollers located at each end of the carriage assembly, two of the rollers riding on the top of the rails and two of the rollers riding on the bottom of the rails, the rollers rotating about axis of rotation directed across the pair of rails; a drive cable connected to the carriage assembly; a rotatable cam having a center axis about which the drive cable is wound; and a motor operatively coupled to move the carriage assembly and array transducer on the rails, wherein the rotatable cam is oriented so that the axis of rotation of the cam extends substantially orthogonal to the axis of rotation of the rollers.
