1. A system for monitoring blood flow in a patient, the system comprising:
a single-element disc-shaped ultrasound transducer for fastening to the patient; and
a controller subsystem configured to:
control the ultrasound transducer to transmit a series of plane-wave pulses into the patient in a propagation direction;
sample reflections of the plane-wave pulses, received at the ultrasound transducer, from a region within the patient, to generate pulse-Doppler response signals; and
process the pulse-Doppler response signals to calculate a blood flow curve for waveform analysis.
