He has made significant contributions to the field of medical technology, particularly in the area of blood flow measurement. His innovative techniques have advanced the way healthcare professionals monitor and analyze blood flow velocities.
Latest Patents
Powrie holds a patent for a technique titled "Continuous display of peak and mean blood flow velocities." This invention discloses a method for continuously determining and displaying the peak and mean velocities of spectral Doppler information. The technique involves examining received spectral Doppler data over a predetermined period to assess the signal to noise ratio of the Doppler signals. By analyzing individual instantaneous measurements in the power versus frequency domain, the maximum frequency signal component is identified as the peak velocity. Mean velocity is calculated as an intensity weighted mean around the maximum power frequency of the line data. The identified peak and mean velocities are then displayed in contrasting colors on a continuously updated flow velocity versus time spectral display.
