Ultrasound patch continuously tracks blood flow in the brain
The team of researchers released the new technology on May 22.
A team of researchers led by Sheng Juel, professor in the Yu Fengli Family Department of Chemical and Nanoengineering at the UC San Diego Jacobs School of Engineering, disclosed the new technology on May 22.
compared with blood flow measurements recorded by a conventional TCD probe to verify device performance. recorded blood flow velocities in ten arterial segments from 36 healthy volunteers, using four transcranial windows (temporal, orbital, submandibular, and suboccipital) to target the arterial segments.
Tracking changes in blood flow
The team used ultrasound to have participants perform a variety of exercises that then modulate blood flow in specific cerebral arteries.
Volunteers performed maneuvers, vocalizations, and visual stimuli while the researchers performed the measurements. The patch performs changes in cerebral blood flow
Recording by activity.
Transient changes in cerebral blood flow can be impaired by brain diseases, disorders, which suggest promising clinical benefits for ultrasound patch diagnostic applications.
