Official title
SONAS Ultrasound Device for the Detection of Ischemic and Hemorrhagic Stroke
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
