Abstract
A method for imaging with a radiotherapy device is provided. The radiotherapy device includes a movably mounted imaging apparatus with an X-ray source and an oppositely disposed X-ray detector. The method includes preparing a first image with the imaging apparatus from a first imaging direction. The imaging apparatus is moved to a position that permits the preparation of a second image from a second imaging direction extending at an angle to the first imaging direction. The method also includes preparing the second image with the imaging apparatus from the second imaging direction, and verifying the position of an object to be irradiated using the first image and the second image.
Claims10
A method for imaging with a radiotherapy device, the radiotherapy device comprising an imaging apparatus that is movably mounted, the imaging apparatus comprising an X-ray source and an oppositely disposed X-ray detector, the method comprising:
- storing a plurality of different therapeutic beam directions in a treatment plan;
- setting a first imaging direction based on the treatment plan such that the first imaging direction corresponds to a first therapeutic beam direction stored in the treatment plan;
- preparing a first image with the imaging apparatus from the first imaging direction, the preparing of the first image being performed before a therapeutic beam application along the first therapeutic beam direction;
- moving the imaging apparatus to a position that permits the preparation of a second image from a second imaging direction, which extends at an angle to the first imaging direction, and permits the therapeutic beam application along the first therapeutic beam direction;
- preparing the second image with the imaging apparatus from the second imaging direction, the preparing of the second image being performed after the therapeutic beam application;
- and
- verifying a position of an object to be irradiated using the first image and the second image.
A radiotherapy device comprising:
- a therapeutic beam source;
- an imaging apparatus that is movably mounted and comprises an X-ray source and an oppositely disposed X-ray detector;
- a memory configured to store a plurality of different therapeutic beam directions in a treatment plan;
- a control apparatus configured to:
- control the therapeutic beam source and the imaging apparatus during a radiation therapy session in order to apply radiation stored in the treatment plan;
- set a first imaging direction based on the treatment plan such that the first imaging direction corresponds to a first therapeutic beam direction stored in the treatment plan;
- prepare a first image with the imaging apparatus from the first imaging direction, the preparation of the first image being performed before a therapeutic beam application along the first therapeutic beam direction;
- move the imaging apparatus to a position that permits the preparation of a second image from a second imaging direction, which extends at an angle to the first imaging direction, and permits the therapeutic beam application along the first therapeutic beam direction;
- prepare the second image with the imaging apparatus from the second imaging direction, the preparation of the second image being performed after the therapeutic beam application;
- and
- verify a position of an object to be irradiated using the first image and the second image.
