1. A system for treating a patient'"'"'s target tissue with radiation, the system comprising:
- a radiation source that emits x-ray radiation 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 substantially at the beam spot, during the treatment period, with visible or infrared light;
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;
a contact lens comprising a fiducial marker; and
a movement module that moves the radiation source, based on the mapped location of the target tissue in the coordinate system, to deliver radiation to the target tissue.

Abstract
Radiosurgery systems are described that are configured to deliver a therapeutic dose of radiation to a target structure in a patient. In some embodiments, inflammatory ocular disorders are treated, and in some embodiments, other disorders or tissues of a body are treated with the dose of radiation. In some embodiments, target tissues are placed in a global coordinate system based on ocular imaging. In some embodiments, a fiducial marker is used to identify the location of the target tissues.
