Ultrasound Brain Imaging

The skull serves to protect the brain, but also presents a barrier to ultrasound imaging of the brain. Therefore, most critical diagnoses have to be performed with the use of magnetic resonance imaging (MRI) or computed tomography (CT). We are developing a range of techniques to overcome these limitations, work which has culminated in a new, noninvasive approach that holds the promise of producing clearer, more accurate brain images, without the risks of dyes or radiation. Our overall goal is to image critical brain features using a device that is faster, more portable, more robust, and far more economical than CT or MRI. To accomplish this, we are developing novel ultrasound equipment and methodology that exploits ultrasound's superior ability to shape and adjust the imaging beam itself. Over the next several years, we plan to develop this technique into a clinically ready device, able to detect and track millimeter-sized anatomical features and abnormalities. This project could provide extensive benefits toward early diagnosis of brain disorders and injury as well as offer a new tool when repeated monitoring of existing conditions within the brain is needed.

Summary: We are developing a portable, non-radioactive diagnostic tool for brain injury and disorders that could be used in remote locations, at the patient's bedside, or for patients whose condition does not permit the use of MRI or CT.
