Abstract
Disclosed herein is an imaging system for a radiotherapy device which is configured to provide therapeutic radiation to a patient via a source of therapeutic radiation. The imaging system comprises a source of imaging radiation, a CBCT panel detector, and a CT detector, wherein the source of imaging radiation is configured to be adjustable such that in a first configuration it is configured to emit imaging radiation towards the CT detector and in a second configuration it is configured to emit imaging radiation towards the CBCT detector.

An imaging system for a radiotherapy device configured to provide therapeutic radiation to a patient via a source of therapeutic radiation, the imaging system comprising:
- a source of imaging radiation;
- a cone beam computed tomography (CBCT) panel detector;
- and
- a computed tomography (CT) detector;
- wherein the source of imaging radiation is configured to be adjustable such that in a first configuration the source of imaging radiation is configured to emit imaging radiation towards the CT detector and in a second configuration it is configured to emit imaging radiation towards the CBCT detector, wherein, in the second configuration, the source of imaging radiation is configured to emit imaging radiation along a first imaging axis, and the CT detector is positioned adjacent to the first imaging axis.
A radiotherapy device comprising:
- an imaging system, wherein the radiotherapy device is configured to provide therapeutic radiation to a patient via a source of therapeutic radiation, and wherein the imaging system comprises:
- a source of imaging radiation;
- a cone beam computed tomography (CBCT) panel detector;
- and
- a computed tomography (CT) detector, wherein the source of imaging radiation is configured to be adjustable such that in a first configuration it is configured to emit imaging radiation towards the CT detector and in a second configuration it is configured to emit imaging radiation towards the CBCT detector, wherein, in the second configuration, the source of imaging radiation is configured to emit imaging radiation along a first imaging axis, and the CT detector is positioned adjacent to the first imaging axis.
A method for imaging for radiotherapy, the method comprising:

- updating one or more radiation delivery variables based on the image;
- configuring a radiotherapy device to deliver treatment according to the updated radiation delivery variables,
- adjusting the source of imaging radiation to a second configuration wherein, in the second configuration, the source of imaging radiation is configured to emit imaging radiation along a first imaging axis, and the CT detector panel is positioned adjacent to the first imaging axis;
- and
- acquiring a second image using the source of imaging radiation in the second configuration and a Cone Beam Computed Tomography (CBCT) detector panel.
A non-transitory computer-readable medium containing instructions that, when executed by a processor, cause the processor to perform operations comprising:
- acquiring an image using a source of imaging radiation in a first configuration and a Computed Tomography (CT) detector panel prior to radiotherapy treatment;
- updating one or more radiation delivery variables based on the image;
- configuring a radiotherapy device to deliver treatment according to the updated radiation delivery variables;
- adjusting the source of imaging radiation to a second configuration wherein, in the second configuration, the source of imaging radiation is configured to emit imaging radiation along a first imaging axis, and the CT detector panel is positioned adjacent to the first imaging axis;
- and
- acquiring a second image using the source of imaging radiation in the second configuration and a Cone Beam Computed Tomography (CBCT) detector panel.
