In conventional confocal/multiphoton fluorescence microscopy, images are
typically acquired under ideal settings and after extensive optimization of
parameters for a given structure or feature, often resulting in information loss
from other image attributes. To overcome the problem of selective data display,
we developed a new method that extends the imaging dynamic range in optical
microscopy and improves the signal-to-noise ratio. Here we demonstrate how
real-time and sequential high dynamic range microscopy facilitates automated
three-dimensional neural segmentation. We address reconstruction and segmentation
performance on samples with different size, anatomy and complexity. Finally, in
vivo real-time high dynamic range imaging is also demonstrated, making the
technique particularly relevant for longitudinal imaging in the presence of
physiological motion and/or for quantification of in vivo fast tracer kinetics
during functional imaging.
