Pulsed Doppler studies in B-mode ultrasound scanning

EL Yeh and RC Meade

In B-mode ultrasound abdominal studies, vascular structures may be confused with other tissues. A pulsed Doppler unit was coupled to a B- mode scanner by attaching the Doppler transducer to the B-mode transducer. A standardization procedure was designed to assure that the ultrasound beams from the 2 transducers were properly aligned, and that the Doppler focusing was accurate. The Doppler signal may be obtained from any point in the B-mode image in order to differentiate vascular structure from other tissue types.
