Abstract
In an MRI magnet structure for use with a radiation beam source as an assembly, magnet coils of varying diameters are concentrically arranged along a magnetic axis, the magnetic coils not sharing a common inner or outer radius. Mechanical support is provided to retain the magnetic coils in necessary relative fixed positions. The patient bore tube is provided through the assembly and defines a patient bore axis in an essentially horizontal direction such that the magnetic axis is inclined to the patient bore axis by an angle of 30°-60°. At least one radiation therapy beam access cavity provides access in a straight line for a radiation therapy beam to reach a treatment region within the magnet structure.
