An intraluminal sensing system is provided that includes an intraluminal device. The intraluminal device has a flexible elongate member configured to be positioned within a body lumen of a patient, and an ultrasound sensor at a distal portion of the flexible elongate member. The ultrasound sensor is configured to emit an ultrasound pulse in a longitudinal within the body lumen, and to receive Doppler-shifted echoes from the ultrasound pulse. A processor circuit in communication with the ultrasound sensor is configured to: compute a velocity spectrum of particles moving within the body lumen based on the Doppler-shifted echoes; identify features in the velocity spectrum indicative of a lateral position or angular alignment of the ultrasound sensor within the body lumen; and output, to a display in communication with the processor circuit, positioning guidance for the intraluminal device based on the identified features in the velocity spectrum.
