Abstract

Controlling the timing of acquiring x-ray images based on target movement.

Claims (30)

1. A method, comprising:

acquiring data indicative of a motion of a target; and

determining, using a processing device, a timing for when to initiate one or more x-ray images based on the data indicative of the motion of the target, the determining comprising:

determining whether a position of the target, due to the motion, is within a treatment tolerance; and

generating the one or more x-ray images of the target if the position is not within the treatment tolerance.

2. The method of claim 1 , further comprising:

computing the position of the target based on the one or more x-ray images.

3. The method of claim 2 , further comprising:

directing a radiation treatment beam using the position of the target.

4. The method of claim 1 , wherein the data comprises a prior x-ray image.

5. A treatment system, comprising:

an imaging apparatus comprising an x-ray source to generate one or more x-ray images;

a motion detecting apparatus to acquire data indicative of a motion of a target; and

a processing device coupled with the imaging apparatus and the motion detecting apparatus, wherein the processing device is configured to determine a timing for when to initiate the one or more x-ray images based on the data indicative of the motion of the target, wherein to determine the timing the processing device performs the following comprising:

determining whether a position of the target, due to the motion, is within a treatment tolerance; and

initiating the one or more x-ray images of the target if the position is not within the treatment tolerance.

6. The treatment system of claim 5 , wherein the processing device is further configured to perform the following, comprising:

computing the position of the target based on the one or more x-ray images.

7. The treatment system of claim 6 , further comprising:

a radiation delivery system operatively coupled with the processing device to deliver a radiation treatment beam to the target, wherein the processing device is further configured to direct the radiation treatment beam using the position of the target.

8. A non-transitory machine readable medium having instructions, that when executed by a processing device, cause the processing device to perform operations comprising:

acquiring data indicative of a motion of a target; and

determining, using a processing device, a timing for when to initiate one or more x-ray images based on the data indicative of the motion of the target, the determining comprising:

determining whether a position of the target, due to the motion, is within a treatment tolerance; and

generating the one or more x-ray images of the target if the position is not within the treatment tolerance.

9. The non-transitory machine readable medium of claim 8 , wherein the instructions cause the processing device to perform further operations comprising computing the position of the target based on the one or more x-ray images.

10. The non-transitory machine readable medium of claim 9 , wherein the instructions cause the processing device to perform further operations comprising directing a radiation treatment beam using the position of the target.

11. The method of claim 1 , wherein determining the timing for when to initiate the one or more x-ray image comprises determining a timing between a plurality of x-ray images.

12. The treatment system of claim 5 , wherein determining the timing for when to initiate the one or more x-ray image comprises determining a timing between a plurality of x-ray images.

13. The non-transitory machine readable medium of claim 8 , wherein determining the timing for when to initiate the one or more x-ray image comprises determining a timing between a plurality of x-ray images.
