  • Patent number: 12285277
    Abstract: A method of generating corrected fluorescence data of concentrations of a targeted fluorophore in tissue of a subject includes administering first and second fluorescent contrast agents to the subject, the first contrast agent targeted to tissue of interest, the second agent untargeted. The tissue is illuminated with light of a first stimulus wavelength and first data is acquired at an appropriate emissions wavelength; the tissue is illuminated at a second stimulus wavelength and second data is acquired at a second emissions wavelength associated with the second agent, the first and second emissions wavelength differ. Difference data is generated by subtracting the second data from the first data. A system provides for stimulus and capture at multiple wavelengths, with image storage memory and subtraction code, to perform the method. Corrected data may form an fluorescence image, or is used to generate fluorescence tomographic images.

  • Patent number: 12272129
    Abstract: A system may transform sensor data from a sensor domain to an image domain using data-driven manifold learning techniques which may, for example, be implemented using neural networks. The sensor data may be generated by an image sensor, which may be part of an imaging system. Fully connected layers of a neural network in the system may be applied to the sensor data to apply an activation function to the sensor data. The activation function may be a hyperbolic tangent activation function. Convolutional layers may then be applied that convolve the output of the fully connected layers for high level feature extraction. An output layer may be applied to the output of the convolutional layers to deconvolve the output and produce image data in the image domain.
