Abstract: A co-registration system provides a means for spatially warping an optical image of an object with another images of a similar object. The optical image may be a scatter image, and the second image may be the same type of image modality, or may be different. The co-registration may use landmarks selected by a user, or may make use of contour information derived from the images. The system may also include processing of three-dimensional volume data in the form of sets of two-dimensional slices for co-registration.

Abstract: The present invention relates to a method of decomposition of a test sample into constituents thereof. The method proceeds by optically imaging the test sample to obtain a corresponding unknown time-domain resolved signal and decomposes the unknown time-domain resolved signal by comparing the unknown time-domain resolved signal with time-domain resolved reference signals. Furthermore, the method allows the determination of the presence or absence of constituents. Relative quantities may also be determined if sample material properties are known or taken into account. Lifetime decay of the constituents may also be estimated by handling effect of light diffusion in the test sample as time decay.

Abstract: The present invention relates to a method and a system for optical imaging of an object in transmission configuration. The method and system obtain contour coordinates of the object using source/detector configurations references and acquire optical data from a region of interest (ROI) of the object. Then, the method and system apply a weighting factor to said optical data as a function of the contour coordinates, and reconstruct an image of the ROI using the weighted optical data and photon diffusion equation.
