Abstract
A motor suitable for use in a medical imaging environment has (a) a cylindrical outer gear having a bore with a centerline and an internal surface with circumferentially distributed and radially directed teeth, (b) a means for mounting this outer gear such that it is constrained to move in rotational motion about its centerline, (c) a cylindrical planetary gear having a bore and an external surface having circumferentially distributed and radially directed teeth, (d) a means located within the planetary gear bore for applying a fluid pressure driven force to cause it to move in translational-circular motion about the outer gear's centerline, and (e) wherein the teeth of these gears are configured so as to cooperate such that the translational-circular motion of the planetary gear causes the rotational movement of the outer gear.
