  • Publication number: 20100234732
    Abstract: The present invention relates to a method for simultaneously determining the position and velocity of objects. Moreover the method comprising the steps of: 1) simultaneously generating a first signal for determining the velocity and a second signal for determining the position; 2) mixing the first signal with the second signal to form a mixed signal and subsequently transmitting the mixed signal towards an object using a transmitter, so that the mixed signal can be at least partially reflected by the object; and 4) evaluating an echo signal. Such a method may be used for various applications, such as monitoring blood vessel access and/or for pericardiocentesis, as well as for determining the blood flow velocity and the position of blood vessels.
