Abstract: Ultrasound image devices, systems, and methods are provided. An ultrasound imaging system, comprising an intraluminal imaging device configured to be positioned within a body lumen of a patient, the intraluminal imaging device comprising a rotatable, flexible elongate drive cable; and an ultrasound transducer disposed at a distal portion of the drive cable, the ultrasound transducer configured to transmit ultrasound energy into the body lumen and to receive ultrasound echoes associated with the body lumen; and a processor circuit in communication with the intraluminal imaging device and configured to receive, from the ultrasound transducer, signal data corresponding to the received ultrasound echoes; normalize the signal data; remove a low frequency signal component from the normalized signal data; determine a displacement for one or more scanlines of the signal data after removing the low frequency signal component; and generate an image of the body lumen based on the displacement.

Abstract: In an exemplary embodiment, a co-registration system according to the embodiments disclosed herein includes one or more processors, an intravascular ultrasound (IVUS) device including an IVUS imaging probe, an angiogram device, and memory storing instructions. The IVUS device and angiogram device are in communication with the one or more processors. The instructions, when executed by the one or more processors, cause the one or more processors to determine a pull-back speed of the IVUS imaging probe based on received radiological image data from the angiogram device. In addition, the one or more processors determine a beamforming setting for the INTS imaging probe based on the pull-back speed, wherein the determined beamforming setting changes an image quality parameter for a subsequently received IVUS image. And, the one or more processors provide the determined beamforming setting to the IVUS imaging probe.
