Abstract

Images that are associated with an identification of a tracking target of a patient to receive radiation treatment may be received. The images may be sorted into a sequence based on a motion of the patient. The sorted images may be provided via a graphical user interface. The sequence of the sorted images that are based on the motion of the patient may be provided.

First claim

What is claimed is:

1. A method comprising:
receiving a plurality of images that are associated with an identification of a tracking target of a patient to receive radiation treatment;
sorting the plurality of images into a sequence based on a motion of the patient, wherein the motion comprises a respiratory motion of the patient;
receiving an input selection, via a graphical user interface (GUI), to provide the sorted plurality of images in the sequence that is based on the motion of the patient;
causing display of, by a processing device, of the sorted plurality of images, in the sequence, that is based on the motion of the patient in response to the input selection;
providing a contour on each of the sorted images to represent the treatment target of the patient that has been identified;
providing a visual indicator on each of the sorted images to represent the tracking target of the patient that has been identified;
receiving a selection, via the GUI, to stop display of the sorted plurality of images in the sequence;
receiving another selection, via the GUI, to remove at least one image at which the sequence has been stopped from being used to identify the tracking target of the patient; and
identifying the tracking target of the patient without the at least one removed image.

2. The method of claim 1 , further comprising:
receiving an indication that an image of the sorted plurality of images corresponds to a false positive during the providing of the sequence, wherein the false positive is based on a corresponding visual indicator of the image being at a position that deviates from a path associated with other visual indicators of the plurality of images.

3. The method of claim 1 , wherein the sorting of the plurality of images into the sequence based on the motion of the patient is in view of a phase and an amplitude associated with the respiratory motion of the patient when each of the plurality of images was taken of the patient.

4. The method of claim 1 , wherein the plurality of images are x-ray images of the patient.

5. A system comprising:
a memory to store a plurality of images that are associated with an identification of a tracking target of a patient to receive radiation treatment; and
a processing device operatively coupled with the memory to:
receive the plurality of images;
sort the plurality of images into a sequence based on a motion of the patient, wherein the motion comprises a respiratory motion of the patient;
receive an input selection, via a graphical user interface (GUI), to provide the sorted plurality of images in the sequence that is based on the motion of the patient;
cause display of the sorted plurality of images, in the sequence, that is based on the motion of the patient in response to the input selection; and
provide a contour on each of the sorted images to represent the treatment target of the patient that has been identified;
provide a visual indicator on each of the sorted images to represent the tracking target of the patient that has been identified;
receive a selection, via the GUI, to stop display of the sorted plurality of images in the sequence; and
receive another selection, via the GUI, to remove at least one image at which the sequence has been stopped from being used to identify the tracking target of the patient; and
identify the tracking target of the patient without the at least one removed image.

6. The system of claim 5 , wherein the processing device is further to:
receive an indication that an image of the sorted plurality of images corresponds to a false positive during the providing of the sequence, wherein the false positive is based on a corresponding visual indicator of the image being at a position that deviates from a path associated with other visual indicators of the plurality of images.

7. The system of claim 5 , wherein the sorting of the plurality of images into the sequence based on the motion of the patient is in view of a phase and an amplitude associated with the respiratory motion of the patient when each of the plurality of images was taken of the patient.

8. The system of claim 5 , wherein the plurality of images are x-ray images of the patient.

9. A non-transitory computer readable medium comprising instructions that, when executed by a processing device, cause the processing device to:
receive a plurality of images that are associated with an identification of a tracking target of a patient to receive radiation treatment; and
sort the plurality of images into a sequence based on a motion of the patient, wherein the motion comprises a respiratory motion of the patient;
receive an input selection, via a graphical user interface (GUI), to provide the sorted plurality of images in the sequence that is based on the motion of the patient;
cause display of the sorted plurality of images, in the sequence, that is based on the motion of the patient in response to the input selection; and
provide a contour on each of the sorted images to represent the treatment target of the patient that has been identified;
provide a visual indicator on each of the sorted images to represent the tracking target of the patient that has been identified;
receive a selection, via the GUI, to stop display of the sorted plurality of images in the sequence; and
receive another selection, via the GUI, to remove at least one image at which the sequence has been stopped from being used to identify the tracking target of the patient; and
identify the tracking target of the patient without the at least one removed image.

10. The non-transitory computer readable medium of claim 9 , wherein the processing device is further to:
receive an indication that an image of the sorted plurality of images corresponds to a false positive during the providing of the sequence, wherein the false positive is based on a corresponding visual indicator of the image being at a position that deviates from a path associated with other visual indicators of the plurality of images.

11. The non-transitory computer readable medium of claim 9 , wherein the sorting of the plurality of images into the sequence based on the motion of the patient is in view of a phase and an amplitude associated with the respiratory motion of the patient when each of the plurality of images was taken of the patient.

12. The non-transitory computer readable medium of claim 9 , wherein the plurality of images are x-ray images of the patient.
