Publication number: 20230072559Abstract: System and associated methods of use for rapid assessment of visual field integrity. In one embodiment, the device comprises a frame that rests near a patient’s eyes with pinpoint lights or mechanical stimuli that act as visual stimuli mounted at locations within the frame and in the patient’s peripheral visual field. A vantage point in front of the frame allows an operator to view the patient’s eyes during assessment, enabling the operator to maximize the accuracy during both in person and telemedicine assessments. The lights or mechanical stimuli are positioned such that they are visible to patients with a wide range of interpupillary distances, enabling the use of a single-size device for all patients.Type: ApplicationFiled: November 24, 2020Publication date: March 9, 2023Applicant: University of Virginia Patent FoundationInventors: Nina J.

Patent number: 10624588Abstract: A system and method for analyzing bioelectrical signals generated during a deep brain stimulation (DBS) includes an apparatus having a housing having a signal input and a signal output and an electrical circuit disposed within the housing and electrically coupled between the signal input and the signal output. The electrical circuit is configured to receive bioelectrical signals corresponding to a cyclic excitation signal transmitted by a pulse generator during a DBS and generate an output signal comprising a series of timing pulses, wherein each timing pulse simulates an envelope of the cyclic excitation signal. The signal output of the housing is electrically coupleable to an auxiliary trigger input of an imaging system and the series of timing pulses can be used to trigger image data acquisition.Type: GrantFiled: January 16, 2017Date of Patent: April 21, 2020Assignee: GENERAL ELECTRIC COMPANYInventors: Eric William Fiveland, Ileana Hancu, Jeffrey Ashe

Patent number: 10543361Abstract: A system and method for localizing a deep brain stimulation electrode in vivo in a subject or object is provided. A magnetic resonance imaging system obtains MR image data from a volume-of-interest by way of a zero echo time (ZTE) or ultrashort echo time (UTE) pulse sequence, with one or more of a phase domain image and a magnitude domain image being analyzed from the MR image data acquired by the ZTE or UTE pulse sequence. One or more electrodes are localized within the volume-of-interest based on an analysis of the phase domain image and/or magnitude domain image. In localizing the electrodes, a multi-scale correlation-based analysis of the volume-of-interest is performed to estimate at least one of an electrode center and electrode contact locations of the electrode, with the localization being achieved with a fast scan-time and with a high level of accuracy and precision.Type: GrantFiled: February 20, 2018Date of Patent: January 28, 2020Assignee: General Electric CompanyInventors: Sathish Ramani, Rolf Schulte, Ileana Hancu, Jeffrey Ashe, Graeme C.
