Two-photon light sheet microscopy (2P-SPIM)

Multiphoton fluorescence microscopy has proven invaluable for tissue studies with its ability to provide 3D micron-scale resolution in thick/live samples. However it is a point-scanning technique, which limits its imaging speed to typically one image per second (a few 10^5 pixels/second).
Multiphoton light-sheet imaging is emerging as a very efficient method to achieve 50-100x faster two-photon imaging of thick tissues, with the additional benefit of strongly reducing unwanted photobleaching effects.
