Summary:A method for determining geometrical information about a medical treatment arrangement that includes a rotatable treatment radiation source unit is provided. The method includes attaching a phantom to a patient support of the medical treatment arrangement, attaching a calibration module to the rotatable treatment radiation source unit to permit the calibration module to rotate together with the rotatable treatment radiation source unit when the rotatable treatment radiation source unit is rotated, obtaining for each of a plurality of rotational positions of the rotatable treatment radiation source unit a projection image of the phantom and of the calibration module by an image detector, while a part of the calibration module is positioned in a radiation propagation zone between the rotatable treatment radiation source unit and the image detector, evaluating the images, obtaining an evaluation result, and determining geometrical information about the medical treatment arrangement from the evaluation result.
