Patent number: 11890095Abstract: A sensor head for a compact oximeter sensor device includes light sources and light detectors. A compact oximeter sensor device implementation is entirely self-contained, without any need to connect, via wires or wirelessly, to a separate system unit. The sources and detectors are arranged in a circular arrangement having various source-detector pair distances that allow for robust calibration and self-correction in a compact probe. Other source-detector arrangements are also possible.Type: GrantFiled: March 8, 2021Date of Patent: February 6, 2024Assignee: ViOptix, Inc.Inventors: Kate LeeAnn Bechtel, Brian Wilfley

Publication number: 20230248276Abstract: A method for calibrating detectors of a self-contained, tissue oximetry device includes emitting light from a light source into a tissue phantom, detecting in a plurality of detectors the light emitted from the light source, subsequent to reflection from the tissue phantom, and generating a set of detector responses by the plurality of detectors based on detecting the light emitted from the light source. The method further includes determining a set of differences between the set of detector responses and a reflectance curve for the tissue phantom, and generating a set of calibration functions based on the set of differences. Each calibration function in the set of calibration functions is associated with a unique, light source-detector pair. The method further includes storing the set of calibration function in a memory of the self-contained, tissue oximetry device.Type: ApplicationFiled: April 14, 2023Publication date: August 10, 2023Inventors: Kate LeeAnn Bechtel, Brian Wilfley

Patent number: 9257207Abstract: An x-ray collimator can be constructed from multiple subassemblies, which at least includes a first subassembly that reduces the leakage of x-ray radiation between adjacent apertures and a second subassembly that reduces the spill of x-ray radiation around the detector face. Each of these subassemblies has numerous apertures. In the first subassembly these apertures correspond to focal spots on an x-ray source, and in the second subassembly, these apertures are shaped such that the dimensions increase from smaller entrances to larger exits.Type: GrantFiled: November 8, 2011Date of Patent: February 9, 2016Assignee: Triple Ring Technologies, Inc.Inventors: Tobias Funk, Brian Wilfley, Peter Holst
