Imaging Method with a Radiotherapy Device and Radiotherapy Device

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.
