Method and apparatus for quantitative and depth resolved hyperspectral fluorescence and reflectance imaging for surgical guidance

An imaging system, such as a surgical microscope, laparoscope, or endoscope or integrated with these devices, includes an illuminator providing patterned white light and/or fluorescent stimulus light. The system receives and images light hyperspectrally, in embodiments using a hyperspectral imaging array, and/or using narrowband tunable filters for passing filtered received light to an imager. Embodiments may construct a 3-D surface model from stereo images, and will estimate optical properties of the target using images taken in patterned light or using other approximations obtained from white light exposures. Hyperspectral images taken under stimulus light are displayed as fluorescent images, and corrected for optical properties of tissue to provide quantitative maps of fluorophore concentration. Spectral information from hyperspectral images is processed to provide depth of fluorophore below the tissue surface. Quantitative images of fluorescence at depth are also prepared. The images are displayed to a surgeon for use in surgery.

Spectrometric analysis

A method of spectrometric analysis comprises obtaining one or more sample spectra for an aerosol, smoke or vapour sample. The one or more sample spectra are subjected to pre-processing and then multivariate and/or library based analysis so as to classify the aerosol, smoke or vapour sample. The results of the analysis are used for various surgical or non-surgical applications.

The disclosed technology relates to closed-loop medical imaging for a medical environment. Various embodiments provide for a surgical camera, such as an endoscopic camera, comprising one or more image sensors. The image sensors may be configured to capture multispectral image data including one or more images of biological tissue (e.g., surfaces), and may be specifically configured to capture imagery within a surgical environment. For some embodiments, different biological tissues may be visible when illuminated by different wavelengths of a multispectral light source. The wavelength setting for the multispectral light source may be determined based upon a first wavelength setting associated with a first set of multispectral image data and a second wavelength setting associated with a second set of multispectral image data.
