[0301] Radiation Therapy System Implementation – An Overview
[0302] Figure 33 is a perspective view of an exemplary embodiment of an x-ray therapy system 10 having aspects of the present invention for use in treating eye disease. The system is shown with a phantom of the patient's head engaged with the head-chin restraint 160, the head calibrated in the treatment position. System 10 includes a radiotherapy beam delivery module, including, for example, one or more x-ray tubes 112, each having a collimator 118 that produces a closely collimated x-ray treatment beam. System 10 includes a radiotherapy control module or subsystem (not shown), which preferably includes an interface display, a processing module, and a power supply. The system includes an imaging module 400, which may include one or more cameras and associated light sources, such as LEDs or low power lasers.

Abstract
A method, code and system for planning the treatment a lesion on or adjacent to the retina of an eye of a patient are disclosed. There is first established at least two beam paths along which x-radiation is to be directed at the retinal lesion. Based on the known spectral and intensity characteristics of the beam, a total treatment time for irradiation along each beam paths is determined. From the coordinates of the optic nerve in the aligned eye position, there is determined the extent and duration of eye movement away from the aligned patient-eye position in a direction that moves the patient's optic nerve toward the irradiation beam that will be allowed during treatment, while still maintaining the radiation dose at the patient optic nerve below a predetermined dose level.
