Abstract
Described herein are systems and devices for radiotherapy collimation. An example device includes a plurality of elongate members arranged in parallel to one another; and at least one fastener at least partially surrounding the plurality of elongate members, the at least one fastener being configured to apply compression to the plurality of elongate members, where: the plurality of elongate members are individually slidable in an uncompressed state, and the plurality of elongate members are individually fixed in a compressed state.
Claims33
A radiotherapy collimation device comprising:
- a plurality of elongate members arranged in parallel to one another;
- and
- at least one fastener at least partially surrounding the plurality of elongate members, the at least one fastener being configured to apply compression to the plurality of elongate members, wherein:
- the plurality of elongate members are individually slidable in an uncompressed state, and
- the plurality of elongate members are individually fixed in a compressed state.
A multi-leaf collimation device comprising:
- a leaf guide defining an aperture plane, a first axis, and a second axis, wherein the first axis is perpendicular to the second axis, and wherein the second axis is perpendicular to the aperture plane;
- a plurality of leaves arranged within the leaf guide;
- and
- one or more leaf drivers operably connected to the plurality of leaves, wherein the one or more leaf drivers are configured to move the plurality of leaves to form a radiation-beam aperture in the aperture plane, and wherein at least one leaf is moveable along the second axis to extend beyond the aperture plane in a direction toward a subject.
A radiotherapy collimation device comprising:
- a plurality of elongate members arranged in parallel to one another and forming a plurality of loops;
- and
- at least one fastener configured to apply compression to the plurality of elongate members, wherein:
- the plurality of elongate members are individually slidable in an uncompressed state, and
- the plurality of elongate members are individually fixed in a compressed state.
