Apparatus for measuring blood flow using ultrasound doppler and operating method thereof

摘要

A blood flow measuring apparatus using an ultrasonic Doppler according to the present invention includes: a two-dimensional transducer array in which a plurality of transducers for transmitting and receiving ultrasound signals to and from an object are arranged in two dimensions; A plurality of transducers are driven to transmit and receive ultrasonic signals, detect Doppler signals for each of the transducers, and correspond to the Doppler signal having the greatest intensity among the detected Doppler signals. An acoustic window search unit for confirming the transducer; Doppler signals for each of the plurality of steering vectors are detected by beam steering with a plurality of transducers adjacent to each other including the identified transducer, and steering corresponding to a Doppler signal having the greatest intensity among the detected Doppler signals A blood flow searcher that identifies a vector; And a Doppler processing unit that detects a Doppler signal by performing beam steering with the identified steering vector and obtains blood flow information from the detected Doppler signal.
