ROTATABLE GANTRY RADIATION TREATMENT SYSTEM

摘要

A radiation treatment apparatus is described. The radiation treatment apparatus may include a gantry frame and a rotatable gantry structure rotatably coupled to the gantry frame, the rotatable gantry structure being rotatable around a rotation axis passing through an isocenter, with the rotatable gantry structure including a first beam member extending between first and second ends of the rotatable gantry structure. The radiation treatment apparatus may also include a radiation treatment head movably mounted to the first beam member in a manner that allows (i) translation of the radiation treatment head along the first beam member between the first and second ends, and (ii) gimballing of the radiation treatment head relative to the first beam member, the gimballing being characterized by pivotable movement in at least two independent pivot directions defined with respect to the first beam member. Non-coplanar radiation treatment of a tissue volume positioned near or around the isocenter may be achievable with the radiation treatment apparatus.

1. A radiation treatment apparatus, comprising:
a gantry frame; a rotatable gantry structure rotatably coupled to the gantry frame, the rotatable gantry structure being rotatable around a rotation axis passing through an isocenter, the rotatable gantry structure comprising a first beam member extending between first and second ends of the rotatable gantry structure; and a radiation treatment head movably mounted to the first beam member in a manner that allows (i) translation of the radiation treatment head along the first beam member between the first and second ends, and (ii) gimballing of the radiation treatment head relative to the first beam member, the gimballing comprising pivotable movement in at least two independent pivot directions defined with respect to the first beam member, wherein the rotatable gantry structure is rotably coupled and radiation treatment head is movably mounted to provide non-coplanar radiation treatment of a tissue volume positioned near or around the isocenter.
