摘要:

冠状动脉造影是心脏介入手术不可缺少的辅助技术。从冠状动脉造影视频中分割和提取血管是医生对血管中的斑块和狭窄进行定位、评估和诊断的必要前提。本文提出了一种新的视频分割框架,可以从视频序列中提取最清晰、最全面的冠状动脉造影图像,从而帮助医生更好地观察血管的状况。该框架结合了一个三维卷积层从视频序列中提取时空信息和一个二维CE-Net来完成图像序列的分割任务。输入是血管造影视频的几个连续帧,并且输出是分割结果的掩模。从分割和提取的结果来看,尽管冠状动脉造影视频序列的质量较差,我们仍然可以得到很好的分割结果。

英文摘要:

Coronary angiography is an indispensable assistive technique for cardiac interventional surgery. Segmentation and extraction of blood vessels from coronary angiography videos are very essential prerequisites for physicians to locate, assess and diagnose the plaques and stenosis in blood vessels. This article proposes a new video segmentation framework that can extract the clearest and most comprehensive coronary angiography images from a video sequence, thereby helping physicians to better observe the condition of blood vessels. This framework combines a 3D convolutional layer to extract spatial--temporal information from a video sequence and a 2D CE--Net to accomplish the segmentation task of an image sequence. The input is a few continuous frames of angiographic video, and the output is a mask of segmentation result. From the results of segmentation and extraction, we can get good segmentation results despite the poor quality of coronary angiography video sequences.
