System and method for radiotherapeutic treatment

1. A system for radiotherapeutic treatment of a patient, the system comprising:

a patient carrier for receiving the patient,

means for monitoring positions of at least two different body parts of the patient,

a processor, coupled to the means for monitoring positions, the processor configured to analyze the monitored positions to determine, for each body part of the at least two body parts, a displacement of the respective body part with respect to a particular desired position, and

feedback means, coupled to the processor, for interacting with the patient, the feedback means configured to provide feedback to the patient concerning the displacement of the respective body part, the feedback means including a display spaced and positioned relative to the patient carrier to enable the patient to be positioned between the patient carrier and the display,

wherein the processor is configured to

(i) determine when an impending displacement of the respective body part with respect to the particular desired position will occur,

(ii) determine whether the patient typically overcompensates in response to feedback from the feedback means instructing the patient to make a compensating movement of the respective body part, wherein the determination of whether the patient typically overcompensates is based on stored information related to monitored movements of the patient on the patient carrier, and

(iii) responsive to the determination that the patient typically overcompensates, determine a lesser compensating movement than required to position the respective body part of the patient in the particular desired position, and

wherein the feedback means are configured to provide the lesser compensating movement to the patient before the impending displacement occurs.

2. A system for radiotherapeutic treatment as claimed in claim 1 , wherein the feedback means are configured to move the respective body part in order to undo the displacement.

3. A system for radiotherapeutic treatment as claimed in claim 1 , wherein the feedback means are configured to restrict a freedom of movement for the respective body part based on the displacement by raising a dividing wall or inflating air bags of the patient carrier.

4. A system for radiotherapeutic treatment as claimed in claim 1 , wherein the processor is further configured to determine a need for the compensating movement of the respective body part and wherein the feedback means are configured to communicate the need for the compensating movement of the respective body part.

5. A system for radiotherapeutic treatment as claimed in claim 4 , wherein the processor is further configured to determine a desired direction of the compensating movement and wherein the feedback means are configured to indicate the desired direction.

6. A system for radiotherapeutic treatment as claimed in claim 4 , wherein the processor is further configured to determine a desired extent of the compensating movement and wherein the feedback means are configured to indicate the desired extent.

7. A system for radiotherapeutic treatment as claimed in claim 6 , wherein the processor is further configured to determine a desired extent of the compensating movement and wherein the display is configured to utilize color coding for indicating the desired extent.

8. A system for radiotherapeutic treatment as claimed in claim 4 , wherein the display is configured to display a body representing figure and indicate, for each body part of the at least two body parts, the need for the compensating movement by visually highlighting a respective one of the at least two body parts in the body representing figure.

9. A system for radiotherapeutic treatment as claimed in claim 1 , wherein the feedback means are configured to provide visual and/or acoustic feedback.

10. A system for radiotherapeutic treatment as claimed in claim 1 , wherein the processor is further configured to determine a score indicating how well the patient keeps an expected posture based on previously monitored positions.

11. A system for radiotherapeutic treatment as claimed in claim 1 , wherein the feedback means are configured to provide tactile feedback directly to each body part.

12. A system for radiotherapeutic treatment as claimed in claim 1 , wherein the determination of when the impending displacement will occur is based on previously monitored radiotherapeutic treatments of at least one further patient.

13. A method of controlling patient movements with a system including a plurality of cameras, pressure sensors, and/or heat sensors, a processor, and a display, the method comprising:

monitoring, with the plurality of cameras, pressure sensors, and/or heat sensors, positions of at least two different body parts of the patient,

analyzing, with the processor, the monitored positions to determine, for each body part of the at least two body parts, a displacement of the respective body part with respect to a particular desired position,

providing, with the display, feedback to the patient concerning the displacement of the respective body part for informing the patient about the displacement of the respective body part, wherein the display is spaced and positioned relative to the patient carrier to enable the patient to be positioned between the patient carrier and the display,

determining, with the processor, when an impending displacement of the respective body part with respect to the particular desired position will occur,

determining, with the processor, whether the patient typically overcompensates in response to feedback from the feedback means instructing the patient to make a compensating movement of the respective body part, wherein the determination of whether the patient typically overcompensates is based on stored information related to monitored movements of the patient on the patient carrier, and

responsive to the determination that the patient typically overcompensates, determining, with the processor, a lesser compensating movement than required to position the respective body part of the patient in the particular desired position, and

providing, with the display, the lesser compensating movement to the patient before the impending displacement occurs.

14. A method of controlling patient movements as claimed in claim 13 , further comprising determining a score indicating how well the patient keeps an expected posture based on previously monitored positions.

15. A computer program product stored on a non-transitory computer-readable medium for use in a method of controlling patient movements, the computer program product configured to cause a processor to perform the method as claimed in claim 13 .

16. A system for radiotherapeutic treatment of a patient, the system comprising:

a patient carrier for receiving the patient,

at least one detector configured to monitor positions of at least two different body parts of the patient,

a processor, operatively coupled to the at least one detector, the processor configured to analyze the monitored positions to determine, for each body part of the at least two body parts, a displacement of the respective body part with respect to a particular desired position, and

a display, operatively coupled to the processor, for interacting with the patient, the display configured to provide feedback to the patient concerning the displacement of the respective body part, wherein the display is spaced and positioned relative to the patient carrier to enable the patient to be positioned between the patient carrier and the display,

wherein the processor is configured to

(i) determine when an impending displacement of the respective body part with respect to the particular desired position will occur,

(ii) determine whether the patient typically overcompensates in response to feedback from the feedback means instructing the patient to make a compensating movement of the respective body part, wherein the determination of whether the patient typically overcompensates is based on stored information related to monitored movements of the patient on the patient carrier, and

(iii) responsive to the determination that the patient typically overcompensates, determine a lesser compensating movement than required to position the respective body part of the patient in the particular desired position, and

wherein the display is configured to provide the lesser compensating movement to the patient before the impending displacement occurs.

17. A system for radiotherapeutic treatment as claimed in claim 16 , wherein the at least one detector comprises one or more of a camera, a pressure sensor or a heat sensor.

18. A system for radiotherapeutic treatment as claimed in claim 16 , wherein the processor is further configured to determine a score indicating how well the patient keeps an expected posture based on previously monitored positions.
