Abstract

We propose novel frequency-domain data types, that show hybrid features to those of phase and AC intensity, i.e., better CNR features than phase data while preserving preferential sensitivity to deep tissue regions (like phase data). We show the CNR features of some of the novel data types in the dual-slope source-detector arrangement in the semi-infinite homogeneous medium and in the two-layer geometries. The results show that these novel data types indeed may have some hybrid features of AC and phase and may have a potential application in imaging of tissue.
