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.
Claims18
A system, for treating a target tissue of an eye with x-ray radiation, comprising:
- a radiation source configured to emit x-ray beams at the target tissue of the eye;
- an alignment system configured to align the x-ray beams with an axis traversing the target tissue and, based on an indication of a location of the target tissue, directs the x-ray beams to be emitted toward the target tissue;
- and
- a holder configured to stabilize the eye during emission of the x-ray beams and comprising a fiducial marker configured to provide the indication of the location of the target tissue.
A system, for treating a target tissue with x-ray radiation, comprising:
- a radiation source that emits an x-ray beam and comprises an imageable light source that indicates an approximate center of a beam spot of the x-ray beam at the target tissue;
- an alignment system that aligns the x-ray beam with an axis traversing the target tissue and that positions the radiation source such that a trajectory of the x-ray beam traverses the target tissue;
- an eye holder that engages an eye during emission of the x-ray beam, the eye holder comprising a fiducial marker that provides an indication of a location of the target tissue;
- and
- a processing module that outputs to the alignment system a direction for the x-ray beam to be emitted toward the target tissue based on a location of the fiducial marker that provides indication of a location of the target tissue.
A system, for treating a target tissue of an eye with x-ray radiation from an x-ray radiation source, comprising:
- an eye holder comprising a fiducial marker along an axis traversing the eye;
- an alignment system having a coordinate system defining the axis traversing the target tissue;
- and
- a processing module that outputs to the alignment system, based on the fiducial marker, a direction for the x-ray radiation emitted from the x-ray radiation source toward the target tissue.
