ORTHOVOLTAGE RADIOTHERAPY
First Claim
1. A system for treating a patient'"'"'s target tissue with radiation, the system comprising:
- a radiation source having a collimator that collimates radiation emitted from the radiation source during a treatment period;
a targeting module that emits a target light that corresponds to a beam spot of the emitted radiation;
an imaging system that repeatedly images the target tissue during the treatment period;
a mapping module that maps a location of the target tissue, based on the images of the imaging system during the treatment period, in a coordinate system; and
a movement module that moves the radiation source, based on the mapped location of the target tissue in the coordinate system, to delivery radiation to the target tissue.

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, inflammatory ocular disorders are treated, specifically macular degeneration. In some embodiments, other disorders or tissues of a body are treated with the dose of radiation. In some embodiments, the target tissues are placed in a global coordinate system based on ocular imaging. In some embodiments, the target tissues inside the global coordinate system lead to direction of an automated positioning system that is directed based on the target tissues within the coordinate system. 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.

13. A system for treating a patient'"'"'s target tissue with radiation, the system comprising:
-
a radiation source and a collimator that collimates the radiation emitted from the radiation source; a targeting module that emits a laser light that indicates a beam spot of the emitted radiation at the target tissue; an imaging system that repeatedly images the target tissue with visible or infrared light; a mapping module that maps a location of the target tissue, based on the images of the imaging system, in a coordinate system; and a motion module that moves the radiation source to a position, based on data from the mapping module, to deliver radiation to the target tissue. - View Dependent Claims (14, 15, 16, 17, 18)
