SPECTRAL UNMIXING FOR IN-VIVO IMAGING

摘要

Described herein are systems and methods for spectral unmixing of in vivo light data. The spectral unmixing separates image data according to spectra from multiple internal light sources in an effort to isolate one or more spectrum of interest. The spectral unmixing obtains images with a combination of different and known excitation and emission limits. The spectral unmixing then uses an iterative solution process to separate spectra for the multiple fluorescent light sources, and provides a spectrum and/or a spatial distribution map for at least one of the internal light sources.
