Method and apparatus for non-invasively visualizing blood vessels

摘要: Apparatus for transcutaneously producing visual images of the internal dimensions blood vessels in human body is disclosed including an ultrasonic pulsed Doppler velocity detector having a transducer adapted to transmit beam ultrasound toward vessel and detect reflected from moving particles. The held by mechanical arm capable sensing position orientation transducer. are combined with distance therefrom locate oscillographic storage display unit. A frequency employed intensify unit write spot on whenever output above pre-set amplitude indicating flow within vessel. Method use apparatus produce visualizations also disclosed.
