Using a rotating 2D x-ray imager as an imaging device to perform target tracking during radiation treatment delivery
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.
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.
