Publication number: 20230394660Abstract: Given a specific imaging device and systems further described herein, wound characteristics of a wound fluoresce with a unique spectral signature when subjected to excitation light with a known wavelength or range of wavelengths. Images captured therefrom are subject to analyses by one or more analysis modules trained using one or more of reflectance images and/or data, fluorescence images and/or data, RGB image data, RGB color data, and wound characteristics data. Wound sizes, boundaries, bacterial presence, and other characteristics may be quantified and graphically represented as an overlay on the original wound image along with documentation related to the wound. Reflectance, fluorescent, and thermal images of the wound may be acquired, subject to analyses with the trained analysis modules, and two or more of the analyzed images may be overlaid to form a composite image upon which areas of interest from each image is highlighted or otherwise indicated.Type: ApplicationFiled: August 14, 2023Publication date: December 7, 2023Applicant: MOLECULIGHT INC.Inventors: Ralph DaCOSTA, Todd E.

Patent number: 11826208Abstract: A surgical imaging system is described. The system includes first and second optical assemblies. Each optical assembly defines a respective optical axis, and each includes a respective set of one or more optics for adjusting field-of-view (FOV) and focus and a respective camera for capturing an image. The system includes a controller for controlling the optical assemblies and for switching the surgical imaging system between a coupled configuration and an uncoupled configuration. In the coupled configuration, the first optical assemblies are controlled to adjust the respective sets of optics and/or the respective optical axes in dependence on each other. In the uncoupled configuration, the optical assemblies are controlled to adjust the respective sets of optics, and the respective optical axes independently of each other.Type: GrantFiled: November 10, 2020Date of Patent: November 28, 2023Inventors: Michael Frank Gunter Wood, Cameron Anthony Piron, Tammy Kee-Wai Lee, Kamyar Abhari, Kai Michael Hynna

Patent number: 11819292Abstract: Methods and systems for providing feedback during a medical procedure. The 3D position and orientation of a tracked tool are determined, relative to a site of the medical procedure, based on tracking information received from a tracking system. The 3D position and orientation are mapped to a common coordinate space, to determine the 3D position and orientation relative to a field-of-view (FOV) of an optical camera that is capturing an optical image of the site. Navigational information associated with the 3D position and orientation is determined. A virtual representation of the navigational information overlaid on the FOV and displayed. The displayed virtual representation is updated when the 3D position and orientation of the tracked tool changes or when the FOV changes, in accordance with the change.Type: GrantFiled: July 16, 2021Date of Patent: November 21, 2023Inventors: Kamyar Abhari, Stewart David McLachlin, Kai Michael Hynna, Gal Sela, Jared Rowland Shoup, Michael Peter Bulk, Kelly Noel Dyer
