| Abstract: | An experimental study on the characteristics of emboli by ultrasonic methods is presented in this paper. In order to acquire embolic signals, based on transcranial Doppler(TCD)blood flow analyzer, a two channel blood flow analyzer was set up. Programs of analog data collection both in frequency and time domains, spectrum analyzing, and system control are developed on the TMS320C25 high speed digital signal processing (DSP) board. Experimental results showed that it can be a good method to test emboli both from time domain delay and change of characteristics in frequency spectrum. |
