Intravascular imaging assessment for stent deployment, and associated systems, devices, and methods

A system includes processor circuitry that receives an intraluminal image of a body lumen. The processor circuit identifies a stent edge within the intraluminal image and calculates a distance between the stent edge and the vessel wall. The processor circuit additionally compares a distance between the stent edge of the intraluminal images and the blood vessel to a threshold distance and identifies which intraluminal images correspond to distances exceeding the threshold. The processor circuit also outputs a longitudinal view of the body lumen to a display, the longitudinal view identifying a location along the stent at which a distance between the stent and the vessel wall exceeds the threshold distance. 一种系统包括接收身体管腔的管腔内图像的处理器电路。所述处理器电路识别所述管腔内图像内的支架边缘，并且计算所述支架边缘与所述血管壁之间的距离。所述处理器电路另外将所述管腔内图像的所述支架边缘与所述血管之间的距离与阈值距离进行比较，并且识别哪些管腔内图像对应于超过所述阈值的距离。所述处理器电路还向显示器输出所述身体管腔的纵向视图，所述纵向视图识别沿着所述支架的位置，在所述位置处，所述支架与所述血管壁之间的距离超过所述阈值距离。
