Orthovoltage radiotherapy

摘要

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.

主权项

1. 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.
