Patent number: 11989860Abstract: Generally described, one or more aspects of the present application correspond to systems and techniques for spectral imaging using a multi-aperture system with curved multi-bandpass filters positioned over each aperture. The present disclosure further relates to techniques for implementing spectral unmixing and image registration to generate a spectral datacube using image information received from such imaging systems. Aspects of the present disclosure relate to using such a datacube to analyze the imaged object, for example to analyze tissue in a clinical setting, perform biometric recognition, or perform materials analysis.Type: GrantFiled: March 6, 2023Date of Patent: May 21, 2024Assignee: Spectral MD, Inc.Inventors: Brian McCall, Wensheng Fan, Jason Dwight, Zhicun Gao, Jeffrey E. Thatcher, John Michael DiMaio

Patent number: 11948300Abstract: Machine learning systems and methods are disclosed for prediction of wound healing, such as for diabetic foot ulcers or other wounds, and for assessment implementations such as segmentation of images into wound regions and non-wound regions. Systems for assessing or predicting wound healing can include a light detection element configured to collect light of at least a first wavelength reflected from a tissue region including a wound, and one or more processors configured to generate an image based on a signal from the light detection element having pixels depicting the tissue region, determine reflectance intensity values for at least a subset of the pixels, determine one or more quantitative features of the subset of the plurality of pixels based on the reflectance intensity values, and generate a predicted or assessed healing parameter associated with the wound over a predetermined time interval.Type: GrantFiled: March 2, 2023Date of Patent: April 2, 2024Assignee: Spectral MD, Inc.Inventors: Wensheng Fan, John Michael DiMaio, Jeffrey E. Thatcher, Peiran Quan, Faliu Yi, Kevin Plant, Ronald Baxter, Brian McCall, Zhicun Gao, Jason Dwight
