Microcomputer-based analyzer for the assessment of Doppler ultrasound blood velocity waveforms

A device has been developed which can quickly and conveniently analyze blood velocity waveforms and evaluate waveform indices. The device can be modified to determine various waveform indices by changing the software. The waveform analyzer digitizes and stores the data, performs a pattern recognition algorithm to recognize individual pulses, and calculates the waveform index. Details of the design and operation of the analyzer are given in this communication.
