The system comes with either a 680 or 750 nm excitation laser channel and is useful for a range of applications including oncology, inflammation, and cardiovascular disease. It is ideal for researchers who are learning 3D fluorescence tomography and do not require the ability to image multiple fluorophores simultaneously. The FMT 1000 is fully upgradeable to the FMT 2000 or FMT 4000 for performing quantitative tomography with a wider range of in vivo applications and imaging agents.
