The TriTom imaging system is based on Photoacoustic Fluorescence Tomography (PAFT) technology that provides unparalleled capabilities for whole body imaging and in vivo characterization of small animal models. Check out this video of Hybrid Photoacoustic/ Fluorescent image of a nude mouse in vivo taken with 780 nm excitation wavelength showing photoacoustic PAtIR contrast (red) and fluorescent of PAtIR contrast (green). The large red ‘disks’ towards the upper abdomen are the PAtIR particles accumulating in the liver.
