Orthovoltage radiotherapy
First Claim
1. A system, for treating an eye with x-ray radiation, comprising:
- an x-ray radiation emitter that emits x-ray radiation toward the eye during a treatment session;
a collimator that collimates the emitted x-ray radiation into a collimated x-ray radiation beam having a cross-section dimension of less than about 6 mm; and
an eye mapping module that repeatedly maps locations of ocular structures in a posterior region of the eye to a coordinate system during the treatment session.

Abstract
A radiosurgery system is described that delivers 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, ocular structures are placed in a global coordinate system, based on ocular imaging, which leads to direction of an automated positioning system. In some embodiments, the position of an ocular structure is tracked and related to a radiosurgery system. In some embodiments, a treatment plan is utilized for a specific disease to be treated and/or structures to be avoided. In some embodiments, a fiducial aids in positioning the system. In some embodiments, a reflection off the eye is used to aid in positioning. 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.

14. A planning system, for delivery of x-ray radiation to an eye, comprising:
-
a processing module that receives an input comprising a biometric parameter of the eye; wherein, based on the biometric parameter, the processing module outputs to an electromotive system a direction for an x-ray beam to be emitted onto the sclera of the eye, the biometric parameter comprising at least one of an axial length of an eye and an anterior chamber depth; and a collimator that collimates the emitted x-ray beam into an x-ray beam having a cross-sectional dimension of less than about 6 mm. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A planning system, for delivery of x-ray radiation to an eye, comprising:
-
means for processing an input comprising a biometric parameter of the eye; means for directing an x-ray beam to be emitted onto the sclera of the eye; wherein, based on the biometric parameter, the means for processing outputs to the means for directing a direction for the x-ray beam to be emitted onto the sclera of the eye, the biometric parameter comprising at least one of an axial length of an eye and an anterior chamber depth; and means for collimating the emitted x-ray beam into an x-ray beam having a cross-sectional dimension of less than about 6 mm. - View Dependent Claims (22, 23)
