摘要：
A method is described, including acquiring, using a camera, an image of a radiation beam incident on a phantom, the radiation beam being emitted by a radiation source. The method further includes determining a beam pointing offset based on the image and calibrating a position of the radiation source based on the beam pointing offset. A calibration system is described including the phantom, the camera, and a processing device. A phantom having an X-ray luminescent material is also described.
