NTU Biomedical Optics Lab - Brain functional imaging

Brain functional imaging

There are four important factors when considering imaging: contrast, resolution, speed, and depth. We work together with world leading brain scientist to develop new technologies to push the boundaries. The aim is to understand how brain works through functional (high-speed) and structural (high-resolution) microscopy.
