Abstract

Peripheral arterial disease (PAD) is a common form of cardiovascular disease. The study proposes a noninvasive investigation of PAD based on the Doppler spectrogram of lower limb arteries. The proposed method consists of spectrogram image binarization using Otsu's thresholding, feature extraction, and automated diagnosis using a support vector machine (SVM)-based classifier. The entire system is implemented in a field-programmable gate array with a target of wearable ultrasound (US) technology. The logarithmic domain-based approximate implementation reduces power consumption and design complexity without affecting performance significantly. Overall, the binary classification accuracy is found to be 90.40 in the study of 125 spectrograms. The back-end design can be useful to integrate with the US system for a cost-effective solution in the resource-constrained platform as well as point-of-care (POC) applications. © 1993-2012 IEEE.
