The present invention provides a combined radiotherapy and MRI system in which an imaging coil is mounted on a mechanical arm. The position of the imaging coil is thus known and in embodiments can be controlled to prevent collisions with the patient and unfavourable interactions between the imaging coil and the radiation beam.

Combined radiotherapy and MRI apparatus

In various embodiments, a system for controlling radiotherapy equipment in a treatment environment includes a controller for receiving, from one or more image capture devices, data indicating the position of one or more objects in the treatment environment. Based on the position data, the controller defines one or more exclusionary zones from which the radiotherapy equipment is excluded. Each zone has a buffer area surrounding one or more of the objects. The controller further directs the radiotherapy equipment such that a radiotherapy treatment plan is delivered without the equipment entering into the exclusionary zones.
