| description | An intraluminal sensing system is provided, which includes an intraluminal device. The intraluminal device includes a flexible elongate member that can be positioned within a body lumen of a patient, and an ultrasound sensor at a distal portion of the flexible elongate member and configured to emit an ultrasound pulse in a longitudinal direction and to receive ultrasound echoes from the pulse. The system also includes a processor circuit in communication with the ultrasound sensor. The processor circuit is configured to compute a velocity spectrum of particles moving within the body lumen based on the received ultrasound echoes and, based on the velocity spectrum, compute a skew index indicative of a position or alignment of the ultrasound sensor within the body lumen. The processor circuit is also configured to output an indication of the skew index. |
