| Popis: | In present study, the effect of the band width of receiving transducer on pulsed Doppler system was studied by usinp; an experimental system. The results of the study indicated that the stagger-tuned wide-band (1.4 MHz,-3dB) transducer(1) can give much more abundant information about blood flow than the narrow band (0.6 MHz, -3dB) transducer. The adequate hand-width of receiving transducer depends on the required signal/noise of transducer and the signal transmitting band. |
