Abstract

Coronary arteries are segmented from the blood pool using mathematical morphology operations from a 3D magnetic resonance spiral acquisition on a continuously breathing healthy volunteer. The segmented volume is maximal intensity projected at different views to yield coronary angiograms showing the left anterior descending artery (LAD), right coronary artery (RCA), and left circumflex artery (LCX). Magnetic resonance coronary angiography provides a retrospective rotating view of the coronary artery tree that complements oblique reformatted sections.

摘要

在一名持续呼吸的健康志愿者身上，利用三维磁共振螺旋采集数据，通过数学形态学运算从血池中分割出冠状动脉。对分割后的容积在不同视角进行最大强度投影，以生成显示左前降支（LAD）、右冠状动脉（RCA）和左旋支动脉（LCX）的冠状动脉造影图像。磁共振冠状动脉造影提供了冠状动脉树的回顾性旋转视图，对斜位重组切片起到补充作用。
