Publication number: 20170319099Abstract: A method for measuring an intracranial fluid bioimpedance in a patient's head, to help detect an abnormality, may involve: securing a volumetric integral phase-shift spectroscopy (VIPS) device to the patient's head; measuring the intracranial fluid bioimpedance with the VIPS device by measuring a phase shift between a magnetic field transmitted from a transmitter on one side of a VIPS device and a magnetic field received at a receiver on another side of the VIPS device, at one or more frequencies; and detecting an abnormality in the intracranial bioimpedance fluid, using a processor in the VIPS device.Type: ApplicationFiled: June 28, 2017Publication date: November 9, 2017Applicant: CEREBROTECH MEDICAL SYSTEMS, INC.Inventors: Mitchell Elliott LEVINSON, Eugene Mark SHUSTERMAN, William Leslie SHEA, Richard WYETH, Erik CHELL

Patent number: 9025727Abstract: 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.Type: GrantFiled: July 23, 2013Date of Patent: May 5, 2015Assignee: Oraya Therapeutics, Inc.Inventors: Michael Gertner, Mark Arnoldussen, Erik Chell, Steven D. Hansen, Junzhong Liang

Patent number: 8855267Abstract: A radiosurgery system is described that delivers 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, ocular structures are placed in a global coordinate system, based on ocular imaging, which leads to direction of an automated positioning system. In some embodiments, the position of an ocular structure is tracked and related to a radiosurgery system. In some embodiments, a treatment plan is utilized for a specific disease to be treated and/or structures to be avoided. In some embodiments, a fiducial aids in positioning the system. In some embodiments, a reflection off the eye is used to aid in positioning. 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.Type: GrantFiled: May 13, 2013Date of Patent: October 7, 2014Assignee: Oraya Therapeutics, Inc.Inventors: Michael Gertner, Steven D.

Patent number: 8848869Abstract: 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.Type: GrantFiled: August 2, 2013Date of Patent: September 30, 2014Assignee: Oraya Therapeutics, Inc.Inventors: Michael Gertner, Mark Arnoldussen, Erik Chell, Steven D.
