Figure 1.

A schematic of the FT system shown in (a) and the constructed system is illustrated in (b). Removable filter slides allow users to easily install different filter sets as necessary for imaging a range of fluorophores, as depicted in the top left of (b). The bottom left part of (b) illustrates the modified mouse bed, holding a mouse phantom, along with a close-up view of the rotating gantry housing the five fiber coupled optical focusers, C1–C5.
