谐波相位磁共振成像（HARP）是一种测量左心室运动的新技术。HARP使用磁共振标记、傅立叶滤波和特殊处理算法来计算心肌运动的关键指标，包括欧拉和拉格朗日应变。本文提出了几种基于HARP的心肌运动可视化新方法。计算和可视化的参数包括运动网格、速度场、应变率、轨迹线、跟踪的欧拉应变和收缩角。计算速度快，完全自动化，具有临床应用的潜力。
Harmonic phase magnetic resonance imaging (HARP) is a new technique for measuring the motion of the left ventricle of the heart. HARP uses magnetic resonance tagging, Fourier filtering and special processing algorithms to calculate key indices of myocardial motion including Eulerian and Lagrangian strain. This paper presents several new methods for visualizing myocardial motion based on HARP. Quantities that are computed and visualized include motion grids, velocity fields, strain rates, pathlines, tracked Eulerian strain, and contraction angle. The computations are fast and fully automated and have the potential for clinical application.
