New noninvasive technique could be used to study the living brain

Researchers from the University of Washington (WA, USA) have utilized a noninvasive light-based imaging technology to study the living brain. This new approach could be harnessed to examine how diseases such as Alzheimer’s and brain tumors affect brain tissue over time. The findings were published recently in the Journal of Biomedical Optics. The authors Woo June Choi and Ruikang Wang, both of the University of Washington, predict that the new technology known as optical coherence tomography (OCT) will enable the study of acute and chronic morphological or functional vascular changes within the deep brain, which has not been commonly achieved...
