Abstract
The evaluation of any method of analysis of Doppler ultrasound blood flow signals is involved and time consuming because of the considerable time necessary to investigate a statistically significant representative population of arteriopathic blood flow waveforms. To overcome these problems we have developed a microcomputer-based system for the capture, storage and processing of spectrum-analysed Doppler ultrasound blood flow signals. This system allows the collection and storage on floppy disk of waveforms from many sites in a large population of arteriopaths and their later analysis using any desired method. Having thus created on disk a suitable population of arteriopathic waveforms the evaluation of any method of waveform analysis, whether existing or new, is a much more convenient and far less time-consuming process. The system described is extremely versatile, for example in addition to the collection of data for postprocessing the system is also used for the real-time analysis of blood flow waveforms.
