Both pulsed and continuous wave Doppler ultrasound systems are finding increased application in the noninvasive assessment of peripheral and carotid arterial disease. An important aspect of such systems is the use of real-time Doppler spectral analysis. It has been shown that spectral analysis can enhance the diagnostic, accuracy and, in the case of carotid assessment, can potentially provide a means for quantification. This paper critically reviews the methods available for real-time analysis and relates the requirements and problems to the design of systems for routine clinical use.
