A medical technology facility includes a functional component, a carrier arrangement provided so as to position the functional component in a space, at least one additional component configured to be positioned and/or formed differently in different positions of the carrier arrangement, and a control facility. In order to form a collision protection system, the control facility is configured to: update a digital movement model of the medical technology facility, wherein the digital movement model maps the carrier components and the functional component with their movability based on position data that indicates prevailing positions of the carrier components; evaluate the prevailing movement model so as to detect possibly impending collisions with at least one subject and/or object that is located in the movement region and that is mapped in the movement model; and implement at least one collision protection measure when an impending collision is detected.
