  • Patent number: 11013456
    Abstract: Under one aspect, a method of displaying medical information about a subject having a plurality of regions includes: resolving light obtained from each region of the plurality of regions into a corresponding spectrum; selecting a portion of each spectrum, the selected portion including medical information about the corresponding region; constructing an image based on the selected portion of each spectrum; and projecting the image onto the subject. Under another aspect, a method of displaying medical information about a subject that has a plurality of regions includes: resolving light obtained from each region of the plurality of regions into a corresponding spectrum; selecting a portion of each spectrum, the selected portion including medical information about the corresponding region; constructing a spectral image based on the selected portion of each spectrum; displaying an image of the plurality of regions; and displaying the spectral image overlying the image of the plurality of regions.

  • Publication number: 20200267336
    Abstract: An apparatus for analyzing a subject including a hyperspectral image module is provided. It is used to identify a suspect region of a subject by using a hyperspectral sensor (for obtaining a hyperspectral image of the subject), a control computer including a processor unit (PU) and a computer readable memory (CRM) (for controlling and is in electronic communication with the sensor), a control software module including instructions stored in the CRM and executed by the PU (for controlling said at least one operating parameter of the sensor), a spectral calibrator module including instructions stored in the CRM and executed by the PU (for applying a wavelength dependent spectral calibration standard constructed for the sensor to a hyperspectral image), and a light source for illuminating the subject. An optional contact probe module is used to collect a signal of the suspect region for medical diagnosis.

  • Publication number: 20170150903
    Abstract: Under one aspect, an apparatus for analyzing the skin of a subject includes a hyperspectral sensor for obtaining a hyperspectral image of the subject. The apparatus further includes a control computer that is in electronic communication with the hyperspectral sensor and which controls at least one operating parameter of the hyperspectral sensor. The control computer includes a processor unit and a computer readable memory. The memory includes executable instructions for controlling the at least one operating parameter of the hyperspectral sensor. The memory includes executable instructions for applying a wavelength dependent spectral calibration standard constructed for the hyperspectral sensor to a hyperspectral image collected by the hyperspectral sensor. The apparatus further includes a light source that illuminates the skin of the subject for the hyperspectral sensor.
