心脏病是美国的头号杀手，在早期发现疾病的指标对于治疗和预防至关重要。在本文中，我们评估可视化技术，使冠状动脉疾病的诊断。医学感兴趣的关键物理量是内皮剪切应力（ESS）。低ESS与冠状动脉病变形成部位和疾病快速进展相关。对患者ESS数据进行有效的可视化对于心脏病专家进行快速和彻底的非侵入性评估至关重要。我们提出了一个任务分类的基础上形成的用户研究领域专家的血液动力学。基于本研究的结果，我们开发了HemoVis，这是一种用于心脏病诊断的交互式可视化应用程序，它使用了一种新颖的冠状动脉树的2D树形图表示。我们提出了一个正式的定量用户研究领域的专家，评估2D与3D动脉表示和彩色地图识别低ESS区域的影响的结果。我们显示统计学上显着的结果表明，我们的2D可视化比3D表示更准确，更有效，一个感知适当的彩色地图导致较少的诊断错误比彩虹彩色地图。
Heart disease is the number one killer in the United States, and finding indicators of the disease at an early stage is critical for treatment and prevention. In this paper we evaluate visualization techniques that enable the diagnosis of coronary artery disease. A key physical quantity of medical interest is endothelial shear stress (ESS). Low ESS has been associated with sites of lesion formation and rapid progression of disease in the coronary arteries. Having effective visualizations of a patient's ESS data is vital for the quick and thorough non-invasive evaluation by a cardiologist. We present a task taxonomy for hemodynamics based on a formative user study with domain experts. Based on the results of this study we developed HemoVis, an interactive visualization application for heart disease diagnosis that uses a novel 2D tree diagram representation of coronary artery trees. We present the results of a formal quantitative user study with domain experts that evaluates the effect of 2D versus 3D artery representations and of color maps on identifying regions of low ESS. We show statistically significant results demonstrating that our 2D visualizations are more accurate and efficient than 3D representations, and that a perceptually appropriate color map leads to fewer diagnostic mistakes than a rainbow color map.
