摘要：
We provide a radiotherapeutic apparatus comprising a patient support, magnetic coils disposed around the patient support for creating a magnetic field therewithin, a radiation source producing a beam of radiation directed toward the patient support and mounted on a rotatable support thereby to rotate the radiation source around the patient support, a slip ring for conveying electrical power to the radiation source and located around the patient support, including at least one electrical interruption therein. This creates a slip ring in which there is no continuous circumferential path, and one in which the current is therefore forced to take a route via one side or the other.
