1. A radiotherapy system with a gantry, the radiotherapy system comprising:
- a therapy beam source defining a beam axis;
a first imaging unit comprising a first X-ray beam and a first X-ray detector opposite one another along a first imaging axis; and
a second imaging unit comprising a second X-ray beam and a second X-ray detector opposite one another along a second imaging axis, wherein the first and second imaging axes are oriented differently, and at least one of the first and second X-ray detectors is disposed tangentially eccentrically relative to the associated imaging axis;
wherein the therapy beam source, the first and second imaging units are mounted rotatably about an isocentric axis.

Abstract
A radiotherapy system is disclosed which provides precise, fast patient positioning. The radiotherapy system includes a gantry on which a therapy beam source that determines a beam axis and two imaging units secured rotatably about an isocentric axis. Each imaging unit includes an X-ray beam and an X-ray detector, opposite one another along respective imaging axes. The imaging axes two imaging units are oriented differently.
