  • Patent number: 10265004
    Abstract: In a blood information measuring apparatus, a plurality of types of light of a superficial layer wavelength set, a middle layer wavelength set, and a deep layer wavelength set are successively applied to a detected hypoxic region. A CCD captures an image under the light of each wavelength set, and an oxygen saturation image is produced independently from one wavelength set to another. A wavelength set determination section creates a histogram of each oxygen saturation image. The wavelength set determination section chooses one of the wavelength sets corresponding to the histogram having a maximum variance as an actual imaging wavelength set. Actual imaging operation is performed using the actual imaging wavelength set, and an oxygen saturation level of each pixel is calculated. The oxygen saturation level is reflected in the image, and the image is displayed on a monitor.

  • Patent number: 10194829
    Abstract: During operation, a system iteratively captures MR signals of one or more types of nuclei in one or more portions of a biological lifeform based on scanning instructions that correspond to a dynamic scan plan. The MR signals in a given iteration may be associated with voxels having associated sizes at three-dimensional (3D) positions in at least a corresponding portion of the biological lifeform. If the system detects a potential anomaly when analyzing the MR signals from the given iteration, the system dynamically modifies the scan plan based on the detected potential anomaly, a medical history and/or an MR-scan history. Subsequent measurements of MR signals may be associated with the same or different: types of nuclei, portions of the biological lifeform, voxels sizes and/or 3D positions.

  • Patent number: 10092197
    Abstract: Reflective surfaces for the apertures of PPG optical components in PPG systems is disclosed. In a PPG system or device, the addition of reflective surfaces around, under, or near the apertures of the optical components can enhance the amount of light received by the light detector. As a result, the measured PPG signal strength can be higher and more accurate compared to the same PPG device without reflective surfaces. The reflective surfaces can reflect and/or recycle light that is incident upon the reflective surfaces back into the skin for eventual capture of the light by the light detectors. In some examples, the reflective surfaces can be diffuse or specular reflectors and/or can be configured to selectively reflect one or more wavelengths of light. In some examples, the back crystal and/or component mounting plane of the PPG system can be made of the same material as the reflective surfaces.
