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.

Radiotherapy device comprising a tilting mechanism

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.

The apparatus also comprises a subject support surface including a portion configured to be located substantially at the isocenter. The subject support surface comprises a subject support surface rotation mechanism configured to rotate the subject support surface about an axis of rotation parallel to and spaced from an axis that passes through the isocenter. The subject support surface also comprises a first section configured to move from a first position to a second position along at least one of a longitudinal and lateral direction. The apparatus also comprises a processor configured to control the longitudinal and/or lateral movement of the first section as a function of the rotation of the subject support surface to maintain the portion of the subject support surface substantially at the isocenter.
