1. A guide system comprising:
a guide unit for guiding a medical object during a medical procedure, the guide unit comprising:
a locking unit, by which the guide unit is disposable on the medical object; and
an aligning element that is in a fixed pose relative to the locking unit, wherein a contour disposed on the aligning element has a higher radiopacity than a remainder of the aligning element, wherein at least a portion of the aligning element is disk-sector-shaped, wherein at least a portion of the contour is circular-arc-shaped; and
an X-ray unit that is configured to:
acquire an image of the contour; and
determine a geometric quantity relating to the contour from the acquired image, wherein the geometric quantity includes a radius or a plurality of radii of the image of the contour,
wherein the guide system is configured to determine, throughout the medical procedure, a three-dimensional position and orientation of the guide unit and the medical object relative to the X-ray unit, including a distance of the guide unit from the X-ray unit, based on the determined geometric quantity, and
wherein the guide system is configured to guide the medical object or control the X-ray unit during the medical procedure based on at least the distance of the guide unit from the X-ray unit.
