H01J 35/20

US Classification:

378121, 378123

Abstract:

A miniature x-ray tube has an anode assembly capable of transmitting x-rays through the anode and over a wide angular range. The anode is in the shape of a cone or truncated cone with an axis on the x-ray tube frame axis, formed of low-Z material with high thermal conductivity for heat dissipation. A target material on the anode body is in a thin layer, which may be approximately 0. 5 to 5 microns thick. In one embodiment a tube evacuation exhaust port at the tail end of the anode assembly forms a cavity for a getter, with a pinched-off tubulation at the end of the cavity.

US Classification:

378 65, 378 68

Abstract:

A portable orthovoltage radiotherapy system is described that is configured to deliver a therapeutic dose of radiation to a target structure in a patient. In some embodiments, inflammatory ocular disorders are treated, specifically macular degeneration. In some embodiments, the ocular structures are placed in a global coordinate system based on ocular imaging. In some embodiments, the ocular structures inside the global coordinate system lead to direction of an automated positioning system that is directed based on the ocular structures within the coordinate system.

Abstract:

A radiosurgery system is described that is configured to deliver a therapeutic dose of radiation to a target structure in a patient. In some embodiments, inflammatory ocular disorders are treated, specifically macular degeneration. In some embodiments, other disorders or tissues of a body are treated with the dose of radiation. In some embodiments, the target tissues are placed in a global coordinate system based on ocular imaging. In some embodiments, the target tissues inside the global coordinate system lead to direction of an automated positioning system that is directed based on the target tissues within the coordinate system. In some embodiments, a treatment plan is utilized in which beam energy and direction and duration of time for treatment is determined for a specific disease to be treated and/or structures to be avoided. In some embodiments, a fiducial marker is used to identify the location of the target tissues. In some embodiments, radiodynamic therapy is described in which radiosurgery is used in combination with other treatments and can be delivered concomitant with, prior to, or following other treatments.

International Classification:

A61N 5/10

US Classification:

378 65, 606 4

Abstract:

Embodiments provide method and 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 and 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 and 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, such as algorithms for gating or interrupting radiation emission, both to ensure treatment goals and to avoid exposure to sensitive structures.

US Classification:

378 65, 606 4

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.
