In radiology diagnosis, medical images are most often visualized slice by slice. At the same time, the visualization based on 3D volumetric rendering of the data is considered useful and has increased its field of application. In this work, we present a case-based study with 16 medical specialists to assess the diagnostic effectiveness of a Virtual Reality interface in fracture identification over 3D volumetric reconstructions. We developed a VR volume viewer compatible with both the Oculus Rift and handheld-based head mounted displays (HMDs). We then performed user experiments to validate the approach in a diagnosis environment. In addition, we assessed the subjects' perception of the 3D reconstruction quality, ease of interaction and ergonomics, and also the users opinion on how VR applications can be useful in healthcare. Among other results, we have found a high level of effectiveness of the VR interface in identifying superficial fractures on head CTs.
在放射学诊断中，医学图像大多是逐片可视化的。与此同时，基于数据的三维体绘制的可视化被认为是有用的，并且其应用领域也在不断扩大。在这项工作中，我们对16名医学专家进行了一项基于案例的研究，以评估虚拟现实界面在通过三维体重建识别骨折方面的诊断效果。我们开发了一种与Oculus Rift和手持式头戴式显示器（HMD）兼容的虚拟现实体浏览器。然后，我们进行了用户实验，以在诊断环境中验证该方法。此外，我们评估了受试者对三维重建质量、交互易用性和人体工程学的感知，以及用户对虚拟现实应用在医疗保健中如何有用的看法。在其他结果中，我们发现虚拟现实界面在识别头部CT上的浅表骨折方面具有很高的有效性。
