我们创建了心肌不确定性查看器(muView或μView)工具,用于探索源自心脏缺血正向模拟的数据。该模拟使用电导率值的集合来了解缺血区域如何影响未受损的各向异性心脏组织。从模拟中得到的数据是多值的和体积的,因此,对于每个数据点,我们都有一个描述心脏电特性的样本集合。μView结合了一套可视化分析方法,可探索缺血区周围的区域,并确定变量的扰动如何改变其效应的传播。
We have created the Myocardial Uncertainty Viewer (muView or μView) tool for exploring data stemming from the forward simulation of cardiac ischemia. The simulation uses a collection of conductivity values to understand how ischemic regions effect the undamaged anisotropic heart tissue. The data resulting from the simulation is multivalued and volumetric and thus, for every data point, we have a collection of samples describing cardiac electrical properties. μView combines a suite of visual analysis methods to explore the area surrounding the ischemic zone and identify how perturbations of variables changes the propagation of their effects.
