Cardiovascular disease (CVD) affects more than 90 million adults in the United States. In recent years, computational hemodynamic models have helped improve our understanding of CVD progression; however, such research workflows can be challenging and unintuitive to operate. We thus developed Harvis, a software platform with a flexible GUI for performing vascular simulations and a VR-capable interface for geometry modification and flow visualization. The aim of Harvis is to streamline and integrate this process for research use and future clinical applications. We also present a user study (n=26) that evaluates interaction with vascular modeling on 2D and VR displays.

心血管疾病（CVD）在美国影响了超过9000万成年人。近年来，计算机血液动力学模型帮助我们加深了对CVD进展的了解。但是，这样的研究工作流程可能具有挑战性并且操作起来不直观。因此，我们开发了Harvis，该软件平台具有用于执行血管模拟的灵活GUI和具有VR功能的界面（用于几何修改和流动可视化）。Harvis的目的是简化和整合此过程，以用于研究用途和未来的临床应用。我们还提出了一项用户研究（n = 26），该研究评估了在2D和VR显示器上与血管建模的相互作用。
