摘要： Data from a target system (616) that exhibits a non-linear relationship between system properties and measurement data, is processed by applying a linear filter (F) to improve resolution and accuracy. The filter reduces inaccuracies that are introduced by an algorithm used to reconstruct the data. The filter is defined by assigning time varying functions, such as sinusoids (200), to elements (210) in a model (Y) of the system to perturbate the elements. The resulting data output from the model is reconstructed using the same algorithm used to subsequently reconstruct the data from the target system. The filter is defined as a matrix (F) that transforms the reconstructed data of the model (X) back toward the known properties of the model (Y). A library of filters can be pre-calculated for different applications. In an example implementation, the system is tissue that is imaged using optical tomography.

摘要： A method of significantly improving the quality of solutions to a system of linear equations. The solution to a system of linear equations is enhanced by: (1) modeling a target medium into a plurality of elements and imposing at least one localized fluctuation into the target medium; (2) measuring an output resulting from at least one localized fluctuation; and (3) processing the measured output to reconstruct a result, determining a correction filter, and applying the correction filter to the result.

摘要： The present invention recognizes that contrary to intuitive expectations, sensitivity and resolution of the data for image reconstruction can be increased by decreasing the absorption or scattering mean free path length of the imaging source energy. Methods are disclosed in this respect for enhancing sensitivity and resolution in the imaging of scattering target media (116). In one method, source energy wavelength is selected to optimize scattering and absorption of the energy while maintaining measurable and acceptable detector signals (112). In another aspect of the invention, the scattering target medium (116) is radially compressed and the imaging source wavelength is then adjusted in conjunction with the compression to improve sensitivity and resolution.

摘要： Computation -saving techniques and stability-adding techniques provide for fast, accurate reconstructions of a time series of images involving large scale 3D problems, such as real-time image recovery in an optical tomography imaging system. A system equation for a target medium (116) such as a tissue is solved using a Normalized Difference Method (NDM) (250). Because of the inherent stability of the NDM solutions, a weight matrix (W) of the system equation can be provided for a given point in a time series (220), then reused without recalculation at subsequent points. Further saving are achieved by decomposing W using singular value decomposition or direst matrix decomposition, transforming it to reduce its dimensions, and/or scaling it to achieve a more stable numerical solution. Values of measured energy (112) emerging from the target medium are back-substituted into the system equation for the different points to obtain the target medium properties.
