 Ultrasound Treatment for Strokes

A cooperative effort with the UALR Department of Physics is actively pursuing several new techniques of improving ultrasound delivery to targets within various parts of the human body.  This is not the usual diagnostic ultrasound technology using 2-10 mHz frequencies; rather, it is centered on lower frequencies ranging from 20 kHz to 1 mHz.  This allows much improved range and much improved penetration of energy through various soft tissues and bony structures.  The object here is to develop simple application techniques that can deliver therapeutic levels of low-frequency ultrasound within the calvarium, within the base of the skull, and within the neck, for treatment of stroke in conjunction with either tPA or microbubbles or both.  It will also have applications in other areas that are easier to reach.  These efforts have been performed in both UALR and UAMS laboratories and are ongoing.

One of our related research posters, Microbubble Potentiated Ultrasound as a Method of Stroke Therapy in a Pig Model; Preliminary Findings, is available online.*
