Abstract
A portable orthovoltage radiotherapy system is described that is configured to deliver a therapeutic dose of radiation to a target structure in a patient. In some embodiments, inflammatory ocular disorders are treated, specifically macular degeneration. In some embodiments, the ocular structures are placed in a global coordinate system based on ocular imaging. In some embodiments, the ocular structures inside the global coordinate system lead to direction of an automated positioning system that is directed based on the ocular structures within the coordinate system.
Claims27
A method, of treating an eye of a patient, comprising:
- providing a geometric representation of the eye, based, at least in part, on anatomic data obtained by an imaging apparatus;
- producing a first x-ray beam and a second x-ray beam, each beam having a width of less than about 6 mm;
- directing the first x-ray beam such that the first beam passes through a first region of a sclera of the eye to a target of a retina;
- and
- directing the second x-ray beam such that the second beam passes through a second region of the sclera to substantially the same target of the retina as the first beam,
- wherein the first region and second region of the sclera are selected based on the geometric representation of the eye;
- and
- wherein the first and second x-ray beams are directed such that central axes of the first and second x-ray beams are projected through the sclera at a distance of from about 0.5 mm to about 6 mm from a limbus of the eye.
A method, of treating an eye of a patient, comprising:
- providing a geometric representation of the eye, based, at least in part, on anatomic data obtained by an imaging apparatus;
- producing a first x-ray beam and a second x-ray beam, each beam having a width of less than about 6 mm;
- directing the first x-ray beam such that the first beam passes through a first region of the eye to a target within the eye;
- and
- directing the second x-ray beam such that the second beam passes through a second region of the eye to substantially the same target within the eye,
- wherein the first region and second region of the eye are selected based on the geometric representation of the eye;
- and
- wherein the first region of the eye comprises a first region of a sclera of the eye and the second region of the eye comprises a second region of the sclera, and an edge-to-edge distance from the first region of the sclera to the second region of the sclera is from about 0.1 mm to about 2 mm.
