Abstract

An apparatus for prompting a patient includes a structure configured to be mounted to a patient support, a screen coupled to the structure, and a projector located at a distance away from the screen. A method of prompting a patient that is being supported on a patient support includes adjusting a position of a screen relative to a projector, the screen having a surface, placing the screen in front of the patient such that the patient can see the surface, and providing an image on the screen using the projector.

Claims

1. A method of providing information to a patient that is being supported on a patient support, comprising:

providing a screen for viewing by the patient; and

providing an image on the screen using a device, wherein the image has (1) a first object indicating a desired inhale level to be achieved and (2) a patient-controlled item that moves in response to a breathing movement of the patient;

wherein the first object comprises a discrete block that moves relative to the screen in a first direction, the patient-controlled item being moveable relative to the screen in a second direction that is different from the first direction; and

wherein the patient-controlled item is moveable in the second direction to intercept the first object that moves in the first direction.

2. The method of claim 1, wherein the image also has a second object prescribing an exhale level.

3. The method of claim 1, wherein a position of the first object with respect to the screen indicates a prescribed time in a future at which to achieve the desired inhale level.

4. The method of claim 1, wherein the object has a first side and a second side, and a distance between the first and second sides of the first object indicates a duration for which to maintain the desired inhale level.

5. The method of claim 1, wherein the screen is non-metallic.

6. The method of claim 1, wherein the screen is a part of an eyewear.

7. The method of claim 1, wherein the act of providing the image comprises using fiber optics to transmit the image from the device.

8. The method of claim 1, wherein the first object comprises a first vertical line that moves across at least a part of the screen.

9. The method of claim 8, wherein the first object comprises a second vertical line representing a prescribed time at which the desired inhale level is no longer needed to be achieved.

10. The method of claim 9, wherein the first vertical line and the second vertical line are parts of a rectangular block.

11. The method of claim 8, wherein the image further includes a second object having a second vertical line representing a prescribed time for achieving the desired exhale level, wherein the first object and the second object are spaced apart from each other in the screen.

12. The method of claim 1, wherein the first object indicates the desired inhale level to be achieved by indicating a constant range of inhale levels that includes the desired inhale level.

13. The method of claim 1, wherein at least a part of the first object has a rectilinear configuration.

14. An apparatus for providing information to a patient, comprising:

a screen with a first surface for viewing by the patient, and a second surface that is opposite from the first surface; and

a device located at a distance away from the screen, wherein the device is configured to provide an image for display on the first surface of the screen, wherein the image has (1) a first object indicating a desired inhale level to be achieved and (2) a patient-controlled item that moves in response to a breathing movement of the patient;

wherein the first object comprises a discrete block that moves relative to the screen in a first direction, the patient-controlled item being moveable relative to the screen in a second direction that is different from the first direction; and

wherein the patient-controlled item is moveable in the second direction to intercept the first object that moves in the first direction.

15. The apparatus of claim 14, wherein the image also has a second object prescribing an exhale level.

16. The apparatus of claim 14, wherein a position of the first object with respect to the screen indicates a prescribed time in a future at which to achieve the desired inhale level.

17. The apparatus of claim 14, wherein the first object has a first side and a second side, and a distance between the first and second sides of the first object indicates a duration for which to maintain the desired inhale level.

18. The apparatus of claim 14, wherein the screen is non-metallic.

19. The apparatus of claim 14, wherein the screen is a part of an eyewear.

20. The apparatus of claim 19, wherein the device comprises a projector, and wherein the apparatus further comprises a projection screen to which the device is configured to project the image, wherein the screen of the eyewear comprises a mirror surface for displaying a reflection of the image.

21. The apparatus of claim 19, wherein the eyewear comprises a pair of glasses.

22. The apparatus of claim 19, wherein the eyewear comprises a goggles.

23. The apparatus of claim 14, further comprising fiber optics for transmitting the image from the device.

24. The apparatus of claim 14, wherein the device is configured for providing backprojected images.

25. The apparatus of claim 14, wherein the screen comprises a non-mirror surface.

26. The apparatus of claim 14, wherein the device is secured to a patient support.

27. The apparatus of claim 14, further comprising a focusing device for focusing the image provided by the device.

28. The apparatus of claim 14, further comprising a processor coupled to the device.

29. The apparatus of claim 28, wherein the processor is configured to cause the device to display the image for instructing the patient to move a body part.

30. The apparatus of claim 14, wherein the image comprises a visual signal for prompting the patient to control a breathing the patient.

31. The apparatus of claim 14, wherein the screen is translatable relative to the device.

32. The apparatus of claim 14, wherein the screen is rotatable relative to the device.

33. The apparatus of claim 14, wherein the device comprises a projector.

34. The apparatus of claim 14, wherein the screen comprises a flat surface.

35. The apparatus of claim 14, wherein the image is configured for instructing the patient to control a breathing of the patient such that the breathing corresponds with a process being performed by a treatment device or an imaging device.

36. The apparatus of claim 14, wherein the image is configured for instructing the patient to control a breathing of the patient such that the breathing corresponds with a motion of a gantry that rotates around the patient.

37. The apparatus of claim 36, wherein the gantry is a part of a CT machine.

38. The apparatus of claim 14, wherein the first object comprises a first vertical line that moves across at least a part of the screen.

39. The apparatus of claim 38, wherein the first object comprises a second vertical line representing a prescribed time at which the desired inhale level is no longer needed to be achieved.

40. The apparatus of claim 39, wherein the first vertical line and the second vertical line are parts of a rectangular block.

41. The apparatus of claim 38, wherein the image further includes a second object having a second vertical line representing a prescribed time for achieving the desired exhale level, wherein the first object and the second object are spaced apart from each other in the screen.

42. The apparatus of claim 14, wherein the first object indicates the desired inhale level to be achieved by indicating a constant range of inhale levels that includes the desired inhale level.

43. The apparatus of claim 14, wherein at least a part of the first object has a rectilinear configuration.
