Abstract :
This paper investigates design, modelling, simulation, and control issues related to Doppler ultrasound involving an embedded system. The aim is to view the Doppler spectrogram commonly used in clinical ultrasound and compute the heart rate and blood velocity in the scanned part. Also, it is possible to detect the presence of turbulent or laminar flow. We introduce the embedded ultrasound imaging device based on the Beagleboard and allow the computations to be distributed within the integrated DM3730 processor beyween its ARM and DSP processors. The resulting system is low in cost, small in size and provide an interface that is comparable to PC-based systems indicating potential for clinical utility.
