Patent ID: 8819877

Claim:
A device for accurately positioning patients for medical imaging or treatment, comprising: a support platform including an elongate torso support section defined by four opposing corners bounding two opposing ends and opposing sides, and a foot support extending from one of the opposing ends of said torso support section at an angle; a fixed base; at least two supporting arms connecting said support platform to said base, one of said at least two supporting arms being attached to one of said two opposing ends of said support platform at a first passive pivot joint and extending at an angle therefrom to a first active pivot joint on said base, and the other of said at least two supporting arms being attached to another of said two opposing ends of said support platform at a second passive pivot joint and extending at an angle therefrom to a second active pivot joint on said base, said at least two supporting arms converging from said two opposing ends of said support platform to said base, all of said first active pivot joint, second active pivot joint, first passive pivot joint and second passive pivot joints having parallel axes of rotation; and a pair of actuators mounted in said base for transmitting a rotational force to said at least two supporting arms at said base, one of said pair of actuators driving said first active pivot joint and the other of said pair of actuators driving said second active pivot joint; whereby synchronous actuation of said at least two supporting arms in a common angular direction moves said supporting platform between a first spatial position and orientation and a second spatial position and orientation.
