Abstract: Systems, methods, and devices for visualizing a reflector in a lumen of a patient are provided. In one embodiment, a system for visualizing a reflector includes an intraluminal ultrasound imaging catheter in communication with a processor circuit. The processor circuit is configured to receive, from the intraluminal ultrasound imaging catheter, ultrasound image signals representative of the lumen and the reflector, generate first ultrasound image data based on the ultrasound image signals, generate second ultrasound image data based on a portion of the ultrasound image signals associated with a second frequency different from the transmit frequency, and output a visualization based on the first and second ultrasound image data to a display. In some aspects, the visualization may serve to identify and distinguish nonlinear reflectors from linear reflectors in the combined image.
