ABSTRACT:
An ultrasonic probe which performs a two-dimensional scan is supported by a mount having a thread which is driven back and forth by a screw along a third axis. When a two-dimensional scan is completed in a first plane, a motor drives the mount along a guide to a second plane for the next scan. The separation between the planes being the same as the resolution in scanning within a plane. A housing having a slot with sidewalls is employed to guide the mount in traveling to successive plane locations along its axis. Means for orienting the housing in angular position and a support assembly provide moveable support to the orienting means so that minimal force is required to position the probe relative to the patient. An "auto-scroll" feature permits the operator to interactively pan through multiple, adjacent two-dimensional planes at programmable speeds and displacements along a third axis. A foot switch provides for hands-free bi-directional scrolling in a "user scroll" mode
