Using iterative methods,LV simulator could accurately track any material point in forward or inverse motion governed by thirteen k-parameters that are presupposed to cardiac motion,and all image planes can be sampled at any time.

• 模拟器可根据描述心脏运动的13个k参数,用迭代计算精确求解出左心室中任一心肌质点随时间前向或反向运动的轨迹,从而模拟TaggedMRI在各影像平面采样和分割所得到的心肌质点的4-D精确坐标。
