Abstract
Official abstract text for this publication.
A method includes receiving, from a volumetric imager, a first image including a target of a patient. The method further includes receiving a second image including the target of the patient. The method further includes tracking, by a processing device, a position of the target using the first image and the second image by maintaining a fixed alignment between a treatment beam of a linear accelerator (LINAC) and a source and detector pair of the volumetric imager during operation of the LINAC.
First claim
Opening claim text (preview).
What is claimed is: 1. A method, comprising: receiving, from a volumetric imager, a first image including a target of a patient; receiving a second image including the target of the patient; and tracking, by a processing device, a position of the target using the first image and the second image, wherein performing the tracking comprises: maintaining a fixed alignment between a treatment beam of a linear accelerator (LINAC) and a source and detector pair of the volumetric imager during operation of the LINAC. 2. The method of claim 1 , wherein the first image is a three-dimensional (3D) intrafraction image, and wherein the 3D intrafraction image is one of: a kilovoltage computed tomography (kV-CT) image, a kilovoltage cone beam computed tomography (kV-CBCT) image, a megavoltage cone beam computed tomography (MV-CBCT) image, or a megavoltage computed tomography (MVCT) image. 3. The method of claim 1 , wherein the first image is a three-dimensional (3D) intrafraction image, and wherein the 3D intrafraction image is a kilovoltage computed tomography (kV-CT) image. 4. The method of claim 1 , wherein the second image is received from one of: the volumetric imager or a static x-ray imager. 5. The method of claim 1 , wherein the fixed alignment is an orthogonal alignment. 6. A non-transitory computer readable medium comprising instructions that, when executed by a processing device, cause the processing device to: receive, from a volumetric imager, a first image including a target of a patient; receive a second image including the target of the patient; and track, by a processing device, a position of the target using the first image and the second image, wherein performing the tracking comprises: maintaining a fixed alignment between a treatment beam of a linear accelerator (LINAC) and a source and detector pair of the volumetric imager during operation of the LINAC. 7. The non-transitory computer readable medium of claim 6 , wherein the first image is a three-dimensional (3D) intrafraction image, and wherein the 3D intrafraction image is one of: a kilovoltage computed tomography (kV-CT) image, a kilovoltage cone beam computed tomography (kV-CBCT) image, a megavoltage cone beam computed tomography (MV-CBCT) image, or a megavoltage computed tomography (MVCT) image. 8. The non-transitory computer readable medium of claim 6 , wherein the first image is a three-dimensional (3D) intrafraction image, and wherein the 3D intrafraction image is a kilovoltage computed tomography (kV-CT) image. 9. The non-transitory computer readable medium of claim 6 , wherein the fixed alignment is an orthogonal alignment.
