Isolated Murine Brain Model for Large-Scale Optoacoustic Calcium Imaging

Frontiers in Neuroscience, 2019
Real-time visualization of large-scale neural dynamics in whole mammalian brains is hindered with existing neuroimaging methods having limited capacity when it comes to imaging large tissue volumes at high speeds.

Volumetric Optoacoustic Imaging With Multi-Bandwidth Deconvolution

IEEE Transactions on Medical Imaging, 2014
Optoacoustic (photoacoustic) imaging based on cylindrically focused 1-D transducer arrays comes with powerful characteristics in visualizing optical contrast. Parallel reading of multiple detectors arranged around a tissue cross section enables capturing data for generating images of this plane within micro-seconds. Dedicated small animals scanners and
