Orthovoltage radiotherapy
First Claim
1. A method, for treating a structure in an eye, comprising:
- engaging, with an eye holder, an outer surface of an eye during a treatment period to maintain the eye in substantially a fixed position during the treatment period;
acquiring optical data indicative of eye motion;
determining, from the optical data, whether the eye is in substantially the fixed position or in a different position than the fixed position; and
emitting an x-ray beam from an x-ray source toward the structure based on the determination of whether the eye is in substantially the fixed position during the treatment period;
when the eye is determined to be in a different position than the fixed position;
(i) aligning the eye, with the eye holder, to be in substantially an aligned the fixed position, or(ii) ceasing or reducing emitting of the x-ray beam from the x-ray source.

Abstract
A radiosurgery system is described that is configured to deliver a therapeutic dose of radiation to a target structure in a patient. In some embodiments, the target tissues are placed in a global coordinate system based on ocular imaging. In some embodiments, a treatment plan is utilized in which beam energy and direction and duration of time for treatment is determined for a specific disease to be treated and/or structures to be avoided. In some embodiments, a fiducial marker is used to identify the location of the target tissues. In some embodiments, radiodynamic therapy is described in which radiosurgery is used in combination with other treatments and can be delivered concomitant with, prior to, or following other treatments.

11. A method, for treating a structure in an eye, comprising:
-
engaging, with an eye holder, an outer surface of an eye to maintain the eye in substantially a fixed position during a treatment period; determining whether the eye is in the fixed position using optical data indicative of eye motion; and emitting x-ray radiation from an x-ray radiation source toward the structure based on the determination of whether the eye is in the fixed position during the treatment period; and when the eye is determined not to be in the fixed position, aligning the eye, with the eye holder, to be in substantially the fixed position. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
