Abstract
A radiotherapy apparatus including a rotatable gantry, a beam generation system, an on-gantry heat transfer system and an off-gantry heat transfer system is disclosed. The beam generation system is attached to the gantry and configured to generate abeam of therapeutic radiation. The on-gantry heat transfer system is configured to rotate with the gantry and includes a first conduit including a first thermally conductive surface, the on-gantry heat transfer system being configured to transfer heat generated by the beam generation system to the thermally conductive surface. The off-gantry heat transfer system includes a second thermally conductive surface, the off-gantry heat transfer system being configured to transfer heat away from the second thermally conductive surface. The first thermally conductive surface is in thermal contact with the second thermally conductive surface to form an interface between the on-gantry heat transfer system and the off-gantry heat transfer system, the interface comprising one of physical contact, or a gas bearing.
