Abstract

As standard practice in orthopedic surgery, the information gathered by analyzing Computer Tomography (CT) 2D images is used for patient diagnosis and planning surgery. Lately, these virtual slices are the input for generating 3D virtual models using DICOM viewers, facilitating spatial orientation, and diagnosis. Virtual Reality (VR) and 3D printing (3DP) technologies are also reported for use in anatomy visualization, medical training, and diagnosis. However, it has not been yet investigated whether the surgeons consider that the advantages offered by 3DP and VR outweigh their development efforts. Moreover, no comparative evaluation for understanding surgeon's preference in using these investigation tools has been performed so far. Therefore, in this paper, a pilot usability test was conducted for collecting surgeons' opinions. 3D models of knee, hip and foot were displayed using DICOM 3D viewer, two VR environments and as 3D-printed replicas. These tools adequacy for diagnosis was comparatively assessed in three cases scenarios, the time for completing the diagnosis tasks was recorded and questionnaires filled in. The time for preparing the models for VR and 3DP, the resources needed and the associated costs were presented in order to provide surgeons with the whole context. Results showed a preference in using desktop DICOM viewer with 3D capabilities along with the information provided by Unity-based VR solution for visualizing the virtual model from various angles challenging to analyze on the computer screen. 3D-printed replicas were considered more useful for physically simulating the surgery than for diagnosis. For the VR and 3DP models, the lack of information on bone quality was considered an important drawback. The following order of using the tools was preferred: DICOM viewer, followed by Unity VR and 3DP.

摘要

作为骨科手术的标准做法,通过分析计算机断层扫描(CT)二维图像收集的信息用于患者诊断和手术规划。最近,这些虚拟切片成为使用DICOM查看器生成三维虚拟模型的输入,有助于空间定位和诊断。虚拟现实(VR)和三维打印(3DP)技术也被报道用于解剖可视化、医学培训和诊断。然而,尚未研究外科医生是否认为3DP和VR提供的优势超过其开发成本。此外,到目前为止,尚未进行比较评估以了解外科医生在使用这些研究工具方面的偏好。因此,本文进行了一项初步可用性测试以收集外科医生的意见。使用DICOM三维查看器、两种VR环境以及三维打印复制品展示了膝盖、臀部和足部的三维模型。在三种病例场景中对这些工具在诊断方面的适用性进行了比较评估,记录了完成诊断任务的时间并填写了问卷。还列出了为VR和3DP准备模型的时间、所需资源和相关成本,以便为外科医生提供全面情况。结果显示,外科医生更倾向于使用具有三维功能的桌面DICOM查看器以及基于Unity的VR解决方案提供的信息,以便从计算机屏幕上难以分析的各个角度可视化虚拟模型。三维打印复制品被认为对手术物理模拟比对诊断更有用。对于VR和3DP模型,缺乏骨质量信息被认为是一个重要缺点。工具的使用顺序偏好如下:DICOM查看器,其次是Unity VR和3DP。
