Abstract

The authors propose an algorithm, that uses multiple frequencies for tomographic imaging with diffusing sources. The use of multiple frequencies improves the resolution that can be achieved for a given source pair number. The authors present an application of the method with Fourier transformed time domain data, obtained from human breast NIR light measurements. The data are acquired simultaneously with a magnetic resonance (MR) scan in order to obtain direct image coregistration
