"New Optical Device Separates Brain and Scalp Blood Flow Signals for Better Diagnostics"

Researchers from the University of Southern California and the California Institute of Technology developed a noninvasive optical device that accurately separates brain and scalp blood flow signals, enhancing diagnostics for conditions like stroke and traumatic brain injury.

• The new optical device utilizes spectroscopy and laser technology to distinguish between hemodynamics in the brain and scalp, improving diagnostic accuracy for neurological issues.
• This innovation addresses limitations of current imaging techniques like MRI and CT, which are costly and less accessible for monitoring conditions such as stroke and traumatic brain injury.
• Developed by teams at the University of Southern California and the California Institute of Technology, the device promises to enhance the understanding of blood vessel dynamics in the brain.
