New OCT tool to study how diseases like dementia, Alzheimer’s, and brain tumors change brain tissue over time. “In the brain, the imaging depth is almost doubled,” said Martin Leahy of the National University of Ireland, Galway. “The authors demonstrate for the first time an application in which this capability opens up a whole new window into the live intact hippocampus, for discovery in brain research.”
From the experimental findings, the authors envision that this new optical coherence tomography (OCT) approach to brain study may enable examination of acute and chronic morphological or functional vascular changes in the deep brain, which has been rarely attempted before in the OCT community.
Choi and Wang used swept-source OCT (SS-OCT) powered by a vertical-cavity surface-emitting...
