Patent ID: 8457279

Claim:
A patient positioning assembly comprising: a patient support device to support a patient thereon; a robotic arm assembly coupled to the patient support device, wherein the robotic arm assembly comprises: a base member; a plate member rotatably mounted on said base member, wherein the plate member is configured to rotate about a first axis to translate the patient support device in a first degree of freedom; an arm extending between a first end and a second end, wherein said first end is rotatably attached to said plate member, wherein the arm is configured to rotate about a second axis to translate the patient support device in a second degree of freedom, wherein the first and second degrees of freedom are used for translations along mutually orthogonal x-, y-, and z-coordinate axes, and wherein said second end is a wrist assembly rotatably connected to the patient support device to allow the patient support device to rotate about roll-, pitch-, and yaw-axes for third, fourth, and fifth degrees of freedom.
