Abstract

Functional imaging of the neonatal brain requires full dataset acquisitions of less than 30 s. The timing electronics in our time-resolved optical tomography instrument have been replaced by new time correlated single photon counting electronics. These allow repeated acquisitions per source of less than 1 s. Full 32-channels datasets can now be acquired during a single functional response. Here we report on a phantom experiment demonstrating that it is possible to record at 800 kHz per timing engine without significant distortion.
