At present, we don't have a non invasive method to check for increased pressure in a patient's brain.
In an ongoing study, researchers in the Massachusetts Institute of Technology's (MIT) Institute for Medical Engineering and Science (IMES) have teamed up with surgeons at Boston Medical Center's Department of Neurosurgery to test a noninvasive method to measure intracranial pressure.
One of the widely used methods is to drill a hole in the skull to insert a catheter or sensor into the brain tissue. The study is supported by a two-year grant from Philips. It will put new ultrasound technology and algorithms into action to analyze intracranial pressure in patients with traumatic brain injuries, strokes, and other conditions.
Heldt also works as an assistant professor in MIT's Department of Electrical Engineering and Computer Science (EECS).
Heldt's research team is refining an algorithm that estimates intracranial pressure based on two measurements that can be taken noninvasively using ultrasound imaging technology.
