  • NON-INVASIVE BILIRUBIN DETECTION USING INDUCED PHOTOREACTION
    Publication number: 20240130619
    Abstract: Techniques are disclosed for measuring a concentration of an analyte in a subject based on reflectance spectra obtained from the subject. The spectra are obtained while and/or before and/or after photoreactions are induced in the subject, where the photoreactions change the reflectivity of the subject. The rate of change of the reflectivity is correlated with the concentration of the analyte.

  • Imaging system and method with scatter correction
    Patent number: 8184767
    Abstract: An imaging technique is provided for acquiring scatter free images of an object. The technique includes acquiring a plurality of projection images of the object using a source and a detector oriented at a plurality of projection angles relative to the object, and generating a plurality of scatter free projection images by correcting the plurality of projection images based on respective ones of a plurality of stored scatter images. The scatter images are generated and stored for each of the projection angles by positioning a scatter rejection plate between the object and the detector. The technique further includes reconstructing a three-dimensional image of the object based on the scatter free projection images.
