More Information
Summary:An intraluminal sensing system (100) is provided that includes an intraluminal device (102). The intraluminal device has a flexible elongate member (106) configured to be positioned within a body lumen of a patient, and an ultrasound transducer (112) at a distal portion of the flexible elongate member. The ultrasound transducer is configured to emit an ultrasound wave along its longitudinal direction in a body lumen and to receive ultrasound waves. A processor circuit in communication with the ultrasound transducer is configured to: compute a velocity spectrum of particles moving within the body lumen based on the received ultrasound waves; identify features in the velocity spectrum indicative of a lateral position or angular alignment of the ultrasound transducer 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.
