Abstract: A radiotherapy device can include a tilting apparatus for tilting a source of radiation, the tilting apparatus comprising: a plurality of guide rails comprising a first guide rail and a second guide rail and a plurality of carriages comprising a first carriage and a second carriage. The first carriage being translatable along the first guide rail and the second carriage being translatable along the second guide rail. The radiotherapy device can also include a support structure for supporting the source of radiation. The support structure being rotatably coupled to each of the first carriage and the second carriage. The first guide rail and the second guide rail can be angled with respect to one another such that translation of the first carriage and the second carriage along the first guide rail and the second guide rail causes tilting of the support structure.

Abstract: A radiotherapy device may comprise a rotatable gantry and a bore tube defining a bore. The bore tube may comprise a first section formed of a first material and a second section formed of a second material. The first section may be configured to minimally attenuate an imaging beam, while the second section may be configured to meet further requirements of the bore tube.

Abstract: The present application relates to a radiotherapy apparatus for delivering radiation to a subject. The apparatus comprises a source of radiation configured to rotate about an isocenter and emit radiation in a radiation plane containing said isocentre. The apparatus also comprises a subject support surface configured such that a portion of the subject support surface can be located substantially at the isocenter. The apparatus also comprises a subject support surface rotation mechanism configured to rotate the subject support surface about an axis of rotation that passes through the isocenter, wherein the subject support surface rotation mechanism is located outside the radiation plane.
