摘要： System and method for detecting and monitoring edema in a patient are described. Initially, a patient's tissue is irradiated with light by a light source. A detector collects reflected light from the patient's tissue and generates data associated with the reflected light. A processing device receives the data and reflected light and calculates an intensity of the reflected light. The processing device then determined, based upon the intensity of the reflected light, whether the patient's tissue exhibits any symptoms of edema. Additionally, the processing device can compare a current intensity of the reflected light against historic information to monitor for any changes in a patient's edema level or severity.

摘要： A system and method for detecting environmental conditions using SWIR hyperspectral imaging. A method may comprise collecting a plurality of interacted photons from at least one location and passing the interacted photons through a tunable filter, filtering the interacted photons into a plurality of wavelength bands. These filtered photons may be detected and analyzed to determine the presence or absence of an environmental condition. A system may comprise at least one collection lens configured to collect at least one plurality of interacted photons from at least one location and a tunable filter for filtering the interacted photons into a plurality of wavelength bands. The system may further comprise a detector configured to detect the filtered photons and generate at least one hyperspectral image representative of the location. The system may further comprise a processor for analyzing the hyperspectral data set and determining the presence or absence of an environmental condition.

摘要： Systems and methods for the detection of calculi in the biliary system are disclosed. The systems include an illumination source, one or more filters that filter a first set of illumination photons and a second set of illumination photons, as well as associated processors and detectors. The system is also designed to generates image data sets and generated information related to the location of the calculi.

摘要： A method for analyzing organ samples using hyperspectral imaging comprising illuminating an organ sample to generate interacted photons, collecting the interacted photons and passing the interacted photons through a tunable filter. The filtered interacted photons are detected to generate a hyperspectral image. A brightfield image is generated and associated with the hyperspectral image. Spectra from locations of interest are extracted and analyzed to assess a characteristic of the organ sample. A system may comprise an illumination source to illuminate an organ sample and generate interacted photons, a collection optics for collecting the interacted photons and a tunable filter to filter the interacted photons. A detector is configured to detect the filtered photons and generate at least one hyperspectral image. The detector may also be configured to generate at least one brightfield image representative of the organ sample.
