Problems solved by technology

Pullback speeds that are too fast or too slow can degrade or distort image quality, and even brief pauses or direction reversals can result in confusing data
Less professional users therefore have difficulty capturing consistent high-quality images

Embodiment Construction

[0041] The present disclosure relates generally to medical imaging, including imaging associated with a body lumen of a patient using an intraluminal imaging device. For example, the present disclosure describes systems, devices, and methods for determining the velocity of movement of an intravascular probe during an IVUS pull-back procedure or other intravascular procedure. In accordance with at least one embodiment of the present disclosure, there is provided a system for determining pullback velocity based on the IVUS image itself and displaying the velocity as navigational information to a clinician with respect to a desired velocity range. This is particularly useful during manually controlled endovascular procedures where a consistent probe velocity (eg, pull-back velocity) within a target range is desired. Determining pullback velocity using the IVUS image itself is different than determining velocity by tracking catheter position in extraluminal images (eg, fluoroscopi...

Abstract

Disclosed is an intraluminal ultrasound imaging system, including a processor circuit in communication with an intraluminal ultrasound imaging catheter, and configured to receive a plurality of intraluminal ultrasound images obtained by the imaging catheter while the imaging catheter is moved through a body lumen of a patient. The processor circuit is further configured to determine a longitudinal translation speed of the imaging catheter based on the plurality of images and a known time interval between images, and display a speed indicator based on the longitudinal translation speed.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Patent Application US 62 / 751185, filed October 26, 2018, which is hereby incorporated by reference in its entirety. technical field [0003] The subject matter described herein relates to systems for medical imaging. Specifically, the disclosed system provides a speed indicator that facilitates the acquisition and display of peripheral intravascular ultrasound or IVUS images during a pullback procedure. The system has particular but not exclusive utility for the diagnosis and treatment of vascular disease. Background technique [0004] Peripheral vascular procedures such as angioplasty and stenting in peripheral veins (inferior vena cava – IVC, iliac, femoral veins), IVC filter retrieval, EVAR and FEVAR (and analogues on abdominal features) plaques Resection and thrombectomy are procedures in which IVUS is used. Different diseases or medical procedures produce p...
