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