Determining tissue oxygen saturation using monte carlo and iterative techniques

A method for determining oxygen saturation includes emitting light from sources into tissue; detecting the light by detectors subsequent to reflection; and generating reflectance data based on detecting the light. The method includes determining a first subset of simulated reflectance curves from a set of simulated reflectance curves stored in a tissue oximetry device for a coarse grid; and fitting the reflectance data points to the first subset of simulated reflectance curves to determine a closest fitting one of the simulated reflectance curves. ... Vioptix Inc

Tissue oximetry probe geometry for robust calibration and self-correction

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. ... Vioptix Inc

Determining tissue oxygen saturation with melanin correction

An oximeter probe that takes into account tissue color (e.g., skin color or melanin content) to improve accuracy when determining oxygen saturation of tissue. Light is transmitted from a light source into tissue having melanin (e.g., eumelanin or pheomelanin). ... Vioptix Inc

Determining absolute and relative tissue oxygen saturation

An oximeter probe is user configurable for being in an absolute reporting mode and a relative reporting mode for measured values. The measured values for the absolute and relative modes include absolute oxygen saturation, relative oxygen saturation, absolute hemoglobin content, relative hemoglobin content, absolute blood volume, relative blood volume. ... Vioptix Inc

Ergonomic handheld oximeter device

An oximeter device has an ergonomically shaped enclosure that allows a user to comfortably grip and use the device during handheld operation. A sensor tip can be easily placed evenly on the tissue surface, so that all sources and detectors are directly on the tissue with even pressure. ... Vioptix Inc

Determining tissue oxygen saturation with quality reporting

An oximeter probe determines an oxygen saturation for the tissue and determines a quality value for the oxygen saturation and associated measurements of the tissue. The quality value is calculated from reflectance data received at the detectors of the oximeter probe. ... Vioptix Inc

Oximetry probe with electronically selectable tissue depth analysis

An oximeter probe includes a probe unit or a base unit and a probe tip where the probe tip has a number of sources and detectors that can be accessed individually or in differing combinations for measuring tissue oxygen saturation at different tissue depth in tissue. A processor of the oximeter probe controls a multiplexer that is coupled to the detectors for selectively collecting measurement information from the detectors via the multiplexer. ... Vioptix Inc

Sleeve for a handheld oximetry probe

Robust calibration and self-correction for tissue oximetry probe

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. ...
