Non-invasive brain probe
A team of researchers in the US has completed the first successful demonstration of a non-invasive optical device to monitor cerebral blood flow in patients who have had an acute stroke.

A
team has completed the first successful demonstration of a non-invasive optical device to monitor cerebral blood flow in patients who have suffered an acute stroke.
The ultimate goal of this research is to improve the management of patients with stroke and other brain disorders by providing continuous bedside monitoring of brain blood flow and metabolism.
‘Our preliminary study demonstrates that blood-flow changes can be reliably detected from stroke patients and also suggests that blood-flow responses vary significantly from patient to patient,’ said lead author Turgut Durduran.
Strokes account for nearly 10 per cent of deaths in the western hemisphere and about 5 per cent of healthcare costs. In the
The device being developed uses embedded optical probes that are placed over major cortical blood vessels in each hemisphere of the brain.
