    • Systems and techniques, including machine-readable instructions, for modeling of nonlinear systems. In one aspect, an apparatus includes a collection of two or more inputs configured and arranged to receive input signals, a collection of two or more outputs configured and arranged to output output signals, a processing unit configured to transform the input signals into the output signals, wherein the transformation is non-linear and treats the non-linear system as a collection of multiple input, single output non-linear systems, and a data storage that stores characteristics of the transformation.

    • The Laser Induced Fluorescence Attenuation Spectroscopy (LIFAS) method and apparatus preferably include a source adapted to emit radiation that is directed at a sample volume in a sample to produce return light from the sample, such return light including modulated return light resulting from modulation by the sample, a first sensor, displaced by a first distance from the sample volume for monitoring the return light and generating a first signal indicative of the intensity of return light, a second sensor, displaced by a second distance from the sample volume, for monitoring the return light and generating a second signal indicative of the intensity of return light, and a processor associated with the first sensor and the second sensor and adapted to process the first and second signals so as to determine the modulation of the sample. The methods and devices of the inventions are particularly well-suited for determining the wavelength-dependent attenuation of a sample and using the attenuation to restore the intrinsic laser induced fluorescence of the sample. In turn, the attenuation and intrinsic laser induced fluorescence can be used to determined a characteristic of interest, such as the ischemic or hypoxic condition of biological tissue.

    • Systems and methods for obtaining images of body organs or other tissue for each of their multiple characterizing aspects, and for classifying different tissue types within the images according to their characterizing aspects, are disclosed herein. The tissue may be irradiated with an ultrasonic signal, and an interaction signal received in return. Sinogram data may be constructed from the received interaction signal, and multiple characterizing data extracted therefrom. The multiple characterizing data representing multiple characterizing aspects may then be matched to tissue type within a database containing information correlating characterizing multi-aspect data with tissue type. Images of the tissue may then be presented with identifiers associating tissue portions with their matched tissue types.
