Abstract The ultrasound carotid vessel imager uses a continuous-wave Doppler flow detector on a hand-guided position sensing arm. The directionally separated flow signals are passed through a two channel audiofrequency real-time spectrum analyser to a microprocessor-controlled image memory and display. Transducer position defines memory address; image data (16 intensity levels) is set by the Doppler signal power detected within a preset broad frequency band. Early results are illustrated
