Abstract

Claims (21)

1. 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.

2. The patient positioning assembly of claim 1 , wherein said base member is configured to be rotatably mounted on a plinth.

3. A patient positioning assembly according to claim 1 further comprising a controller operatively connected to said robotic arm assembly to control the movement of said robotic arm assembly.

4. A patient positioning assembly according to claim 3 , wherein said patient positioning assembly further comprises a sensor system to detect the position of said patient support device relative to a treatment coordinate system, and wherein said controller is operatively connected with said sensor system to receive position data of said patient support device.

5. A patient positioning assembly according to claim 1 , wherein said patient support device comprises a seat with a back.

6. A patient positioning assembly comprising:

a patient support device to patient 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;

a first arm having a first end rotatably attached to said plate member, and a second end, wherein the first arm is configured to rotate about a second axis to translate the patient support device in a second degree of freedom;

a second arm having a first end rotatably attached to the second end of said first arm, and a second end, wherein the second arm is configured to rotate about a third axis to translate the patient support device in a third degree of freedom, wherein the first, second, and third 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.

7. A patient positioning assembly according to claim 6 , wherein said base member is configured to be rotatably mounted on a plinth.

8. A patient positioning assembly according to claim 6 further comprising a controller operatively connected to said robotic arm assembly to control the movement of said robotic arm assembly.

9. A patient positioning assembly according to claim 8 , wherein said patient positioning assembly further comprises a sensor system to detect the position of said patient support device relative to a treatment coordinate system, and wherein said controller is operatively connected with said sensor system to receive position data of said patient support device.

10. A patient positioning assembly according to claim 6 , wherein said patient support device comprises a seat with a back.
