摘要:
A light-guided, ophthalmic-treatment-system for administering therapeutic agents to, into or through the scleral wall of the eye globe using any one of a variety of therapeutic applicators in conjunction with either transcorneal or transpupillary viewing methods or both.

A radiosurgery system describes a therapeutic radiation delivery to a target structure in a patient. The radiosurgery system treats inflammatory ocular disorders; places ocular structures in a global coordinate system based on ocular imaging; automates ocular structures inside the global coordinate system to direction of a positioning system that is directed based on ocular structures within the coordinate system; tracks and relates the position of ocular structures to the status of the radiosurgery system; determines beam energy and direction and duration of time for treatment for a specific disease to be treated and/or structures to be avoided; tracks structure of an eye; holds and fixes the eye is in place; places a fiducial is on the eye to aid in positioning; positions the eye off the refelction; and combines with other treatments and can be delivered concomitant with, prior to, or following other treatments.

Methods and devices for minimally-invasive delivery of radiation to the posterior portion of the eye including a cannula comprising a distal portion connected to a proximal portion and a means for advancing a radionuclide brachytherapy source (RBS) toward the tip of the distal portion; a method of introducing radiation to the human eye comprising inserting a cannula between the Tenon's capsule and the sclera of the human eye and emitting the radiation from the cannula on an outer surface of said sclera.

摘要:
Embodiments provide method/systems for determining alignment of a patient's body part, such as an eye, in an external coordinate system of a treatment or diagnostic device, such as a radiotherapy device, so as to define a reference axis for guiding device operation. Additional embodiments provide image-based methods/systems for aligning, tracking and monitoring motion of a body part and a treatment target in relation to a radiation beam axis. Particular ophthalmic embodiments provide method/systems including an eye- contact guide device and imaging system for aligning and tracking motion of an eye and ocular treatment target in relation to an orthovoltage X-ray beam axis, so as to monitor application of radiation to a lesion, such as a macular lesion of the retina. Particular methods for controlling radiation in response to motion of the target during treatment are described to ensure treatment goals and avoid exposure to sensitive structures.
摘要:
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.
摘要:
The present invention relates, in general, to a method of tracking the movement of the eyeball, and, more particularly, to a method of tracking the movement of the eyeball in eyeball tumor treatment. The present invention also relates to an eyeball tumor treatment system for tracking movement of an eyeball in eyeball tumour treatment.
摘要:
A system for treating an ocular tumor having a cone, a collimator, a light source and a camera is disclosed. The cone includes a cone input and a cone output and is capable of being mounted and un-mounted to a treatment nozzle. The cone input receives radiation from the treatment nozzle for the treatment of the ocular tumor. The collimator is coupled to the cone output and configured to collimate radiation received by the cone output. This collimated radiation is directed to the patient having the ocular tumor. The light source coupled to the cone. The light source is configured to provide a focusing point of the eye of the patient. A camera coupled to the cone monitors the position of the eye of the patient.
摘要:
Afin de réaliser des implants radioactifs versatiles (10) et de permettre la mise en oeuvre de procédés de radiothérapie variés, on utilise des techniques de placage telles que la pulvérisation pour recouvrir des éléments unitaires, tels que des microsphères, des fils et des rubans, de métaux radioactifs (16), de couches de protection (20) et de couches d'indentification (18). Les éléments solides, radioactifs, multicouches et sans soudures sont implantés individuellement ou combinés dans des applicateurs intercavités, avec des tissus et dans des rubans. Dès lors qu'ils présentent des demi-vies et des intensités sélectionnées, ces éléments permettent d'effectuer un traitement flexible, aussi bien de faible intensité que d'intensité élevée, à l'aide d'implants temporaires ou permanents et d'implants de faible intensité, d'intensité élevée ou d'intensité contrôlée, permettant différents types de thérapies.
