Abstract

A radiation system includes a first ring, a radiation source capable of providing radiation suitable for treating a patient, the radiation source secured to the first ring, a second ring located behind the first ring, and an imager secured to the second ring. A radiation system includes a first device having a radiation source capable of generating a radiation beam suitable for treating a patient, and a second device having imaging capability, wherein the first device is oriented at an angle that is less than 180° relative to the second device. A radiation system includes a structure having a first opening, a radiation source rotatably coupled to the structure, an imaging device rotatable relative to the structure, and a processor for controlling a rotation of the radiation source and a rotation of the imaging device, wherein the radiation source is rotatable relative to the imaging device.

First claim

What is claimed is:

1. A patient supporting device, comprising:
a base configured for coupling to a floor, wherein the base is configured to rotate about a first vertical axis;
a first member rotatably coupled to the base, wherein the first member is rotatable relative to the base about a second vertical axis that is different from the first vertical axis;
a second member rotatably coupled to the first member, wherein the second member comprises a first arm, and a second arm rotatable relative to the first arm, and wherein the first arm is configured to move synchronously with a movement of the second arm; and
a platform for supporting a patient, wherein the platform is coupled to the second member, and wherein the second member is configured to move the platform vertically based on synchronous movements of the first and second arms of the second member.

2. The patient supporting device of claim 1 , wherein the base is configured to couple to the floor via a first rail, and wherein the base is configured to move relative to the first rail within a horizontal plane along a path defined by a shape of the first rail.

3. The patient supporting device of claim 1 , wherein the platform is rotatable relative to the second member about a first horizontal axis.

4. The patient supporting device of claim 2 , wherein the base is also configured to move along a second rail.

5. The patient supporting device of claim 2 , further comprising the first rail.

6. The patient supporting device of claim 1 , wherein the second member comprises a first end and a second end that is opposite the first end, and wherein the second member is configured to transfer a weight of the platform from the first end of the second member to the second end of the second member.

7. The patient supporting device of claim 1 , wherein the first member comprises a first end and a second end that is opposite the first end of the first member, and wherein the first member is configured to transfer the weight of the platform from the first end of the first member to the second end of the first member.

8. A medical system comprising the patient supporting device of claim 1 , and a treatment machine.

9. The medical system of claim 8 , wherein the base of the patient supporting device is configured to move from a first position in front of a left side of the treatment machine to a second position in front of a right side of the treatment machine.

10. The medical system of claim 9 , wherein the base of the patient supporting device is configured to move from the first position to the second position while an area of the platform is maintained below an energy source of the treatment machine.

11. The medical system of claim 10 , wherein the treatment machine comprises a radiation treatment machine.

12. The medical system of claim 8 , further comprising an imaging device.

13. The medical system of claim 12 , wherein the first member and/or the second member is configured to move the platform from a first operative position associated with the treatment machine to a second operative position associated with the imaging device, or vice versa.

14. A medical system, comprising:
a treatment machine configured to deliver treatment energy for treating a patient; and
a patient supporting device comprises a platform for supporting the patient;
wherein the patient supporting device also comprises a base configured to move from a first position in front of a left side of the treatment machine to a second position in front of a right side of the treatment machine;
wherein the base is configured for coupling to a floor, and is configured to rotate about a first vertical axis, and wherein the platform is configured to rotate relative to the base about a second vertical axis;
wherein the medical system further comprises a second member configured to move the platform in a vertical direction, the second member comprising a first mechanical part and a mechanical part that are configured to move synchronously with respect to each other.

15. The medical system of claim 14 , wherein the base of the patient supporting device is configured to move from the first position to the second position while an area of the platform is maintained below an energy source of the treatment machine.

16. The medical system of claim 14 , wherein the patient supporting device is configured to place a surface point of the platform below an energy source of the treatment machine.

17. The medical system of claim 14 , wherein the patient supporting device is configured to place the platform at an orientation with respect to the treatment machine, wherein when the platform is at the orientation, a longitudinal axis of the platform forms an acute angle with respect to a machine axis extending from a front of the treatment machine to a back of the treatment machine.

18. The medical system of claim 14 , wherein the second member comprises a first end and a second end that is opposite the first end, and wherein the second member is configured to transfer a weight of the platform from the first end of the second member to the second end of the second member.

19. The medical system of claim 14 , wherein the first member comprises a first end and a second end that is opposite the first end of the first member, and wherein the first member is configured to transfer the weight of the platform from the first end of the first member to the second end of the first member.

20. The medical system of claim 14 , further comprising a rail along which the base of the patient supporting device is configured to move.

21. The medical system of claim 14 , wherein the treatment machine is configured to deliver treatment radiation.

22. The medical system of claim 14 , further comprising an imaging device.

23. The medical system of claim 22 , wherein the platform is moveable from a first operative position associated with the treatment machine to a second operative position associated with the imaging device, or vice versa.

24. The medical system of claim 14 , wherein the first and second mechanical parts of the second member comprise a first arm and a second arm, and wherein the first arm is configured to move synchronously with a movement of the second arm to move the platform vertically.
