Embodiment Construction

[0026] 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 the use of intravascular ultrasound (IVUS) and other imaging modalities by presenting the user with two, three, or more automatically generated boundary options (selected with sequential ranking based on algorithmically determined probabilities). Systems, devices and methods for identification and measurement of boundaries of blood vessels or other organs during use. Current methods of editing vessel or organ boundaries involve manual interaction by the user to redraw or by some means redirect the features that automated algorithms have identified on the image. Such editing techniques may be time-consuming and also difficult or error-prone for some users. The present disclosure reduces the amount of time required for a clinician or other user to edit vessel or organ b...

Abstract

Disclosed is an intraluminal ultrasound imaging system, including a processor circuit in communication with an intraluminal ultrasound imaging catheter, wherein the processor circuit is configured to receive a plurality of intraluminal ultrasound images obtained by the intraluminal ultrasound imaging catheter during movement of the intraluminal ultrasound imaging catheter within a body lumen of a patient. The processor circuit is further configured to select an image from among the plurality of intraluminal ultrasound images, generate at least two border contours associated with the lumen within the selected image, display the border contours associated with the lumen, each overlaid on a separate instance of the selected image, receive a user input selecting one of the border contours; and display the selected image overlaid with the selected border contour.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit to U.S. Provisional Patent Application US62 / 750996, filed October 26, 2018, which is incorporated herein by reference in its entirety. technical field [0003] The subject matter described herein relates to a system for medical imaging. In particular, the disclosed system provides a system for identifying and selecting automatically detected lumen and / or vessel boundaries. The system has particular but non-exclusive utility for the diagnosis and management of vascular disease. Background technique [0004] Intravascular ultrasound (IVUS) is used in both coronary and peripheral vascular procedures such as angioplasty and stenting, IVC-filter retrieval, EVAR and FEVAR (and similar in abdominal features) atherectomy and thrombectomy. Different diseases or medical procedures produce physical features with different sizes, structures, densities, water contents and accessibilit...
