Abstract: Disclosed herein is a patient positioning apparatus for a medical device. The apparatus comprises a patient support apparatus, a support structure configured to extend between the patient support apparatus and a floor of a treatment room to support the patient support apparatus above the floor of the treatment room. The patient support apparatus is rotationally coupled to the support structure. The patient positioning apparatus comprises a rotation mechanism comprising a drive member and is configured to impart a force, via the drive member, to an underside of the patient support apparatus to thereby rotate the patient support apparatus with respect to the support structure. The rotation mechanism is attached to, and supported by, the support structure.

Abstract: The present application relates to a patient support apparatus for a radiotherapy device. The patient support apparatus comprises a support surface and abase. The patient support apparatus also comprises a first connection assembly connecting the surface and the base, the first connection assembly being connected to the surface at a first connection point, wherein the first connection assembly is coupled to a first driving mechanism configured to effect translation of the first connection point in a substantially vertical direction. The patient support apparatus also comprises a second connection assembly connecting the surface and the base, the second connection assembly being connected to the surface at a second connection point, wherein the second connection assembly is coupled to a second driving mechanism configured to effect translation of the second connection point in the substantially vertical direction. The patient support apparatus also comprises a third connection assembly connecting the surface and the base, the third connection assembly being connected to the surface at a third connection point, wherein the third connection assembly is coupled to a third driving mechanism configured to effect translation of the third connection point in the substantially vertical direction, wherein the third connection assembly further comprises a pivot joint at the third connection point configured to enable relative rotation between the surface and the base. The first, second and third driving mechanisms are configured to be independently driven to provide rotation and vertical translation of the surface with respect to the base.

Abstract: A radiotherapy device may comprise a fixed support structure and an inner cover defining a bore. The inner cover may be movable with respect to the fixed support structure from a first position. In an example, the inner cover may be movable from the first position in two dimensions, in a plane of a circular cross section of the inner cover.

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.
