Summary
The purpose of this research study is to test a new medical device, called SONAS. The SONAS
device is a portable, battery-powered ultrasound device to detect strokes in the prehospital
environment, such as emergency vehicles (eg. ambulances, helicopters). To demonstrate the
safety of the device the goal is test it in a small number of healthy volunteers first.
The SONAS device will be used to detect changes in blood flow to the brain through
ultrasound, otherwise known as TransCranial Doppler (TCD). To date, the SONAS device has been
tested extensively in the laboratory, in animals and in human cadavers. The purpose of the
present study is to test the device for safety and efficacy in a small group of healthy
volunteers. This study will test the device on 10 healthy volunteers. Each volunteer will
have a physical examination, neurological examination, and brain MRI both before and after
the TCD test is performed. All of these study procedures will be performed on 1 visit,
lasting approximately 5 hours. The brain MRI's will be used to verify the effectiveness of
the SONAS device on detecting changes in blood flow to the brain.
