Read the full results from this groundbreaking study
At our center, NeuraSignal’s NG2 robotically assisted TCD detected 4x more PFOs than TTE over 3 years. Stroke programs worldwide should strongly consider integrating this technology given the scale of its clinical impact
You can literally train your 15-year-old kid to do this and they would do a really good job at it. You don’t need to have any training on ultrasound to use the robotic system. That’s one of the reasons we like it.
Since implementing NeuraSignal’s world’s 1st and only automated, robotic TCD (NG2) we’ve isolated critical findings, such as embolization, in real-time, that would otherwise be missed. This technology can radically improve clinical and financial value for any private neurology clinics in the USA.
Service is incredible. You guys always answer when we call. The hospital never closes, which means a lot to us. It keeps patient care rolling. You guys have even overnighted probes for us, which was a great help for us to keep patient flow going.
What Is a Transcranial Doppler Ultrasound (TCD)?
TCD is required to become a certified Comprehensive Stroke Center
TCD is a noninvasive and painless ultrasound method that uses sound waves to evaluate blood flow in and around the brain. There is no special contrast or radiation involved in the test. During the TCD exam, high frequency sound waves are transmitted through the tissues of the skull. These sound waves reflect off blood cells moving within the blood vessels, allowing the TCD system to measure the rate and direction of blood flow in the main cerebral arteries known as the Circle of Willis. While most forms of ultrasonography deliver images of the tissue studied, TCD delivers audible sounds that can be heard, recorded, and examined.
Provide insight into subtle hemodynamic changes to quickly aid in the assessment of right-to-left shunt, vasospasm, emboli, and blood flow velocity.
TCD is a non-invasive imaging technique, which means it does not require surgery or injections, reducing patient risk and discomfort.
The NeuraSignal Platform automatically finds the temporal window. Once the transtemporal window is identified, an algorithm finds and locks onto the strongest cerebral blood flow signal. The algorithm was designed to mimic the search of a human technician but responds to real-time data rather than being a fixed search pattern. The signal acquisition time and signal accuracy of NeuraGuide has been shown to be comparable to an expert TCD sonographer1.

TCD machines are often portable, enabling bedside evaluations in critical care units, emergency rooms, and even during surgeries.
