A few years ago it could take several hours to complete a 3D image using a 3D workstation. Thanks to advances in computer science, obtaining results of interest now requires only a few minutes. Many recent 3D workstations or multimedia computers are equipped with onboard 3D virtual patient modeling software, which enables patient-specific preoperative assessment and virtual planning, navigation, and tool positioning. Although medical 3D imaging can now be conducted using various modalities, including computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET), and ultrasonography (US) among others, the highest quality images are obtained using CT data, and CT images are now the most commonly used source of data for 3D simulation and navigation image. If the 2D source image is bad, no amount of 3D image manipulation in software will provide a quality 3D image. In this exhibition, the recent advances in CT imaging technique and 3D visualization of the hepatobiliary and pancreatic abnormalities are featured, including scan and image reconstruction technique, contrast-enhanced techniques, new application of advanced CT scan techniques, and new virtual reality simulation and navigation imaging.
几年前，使用3D工作站完成一幅3D图像可能需要几个小时。得益于计算机科学的进步，现在获取感兴趣的结果仅需几分钟。许多最新的3D工作站或多媒体计算机都配备了板载3D虚拟患者建模软件，该软件能够进行针对患者的术前评估以及虚拟规划、导航和工具定位。尽管现在可以使用多种方式进行医学3D成像，包括计算机断层扫描（CT）、磁共振成像（MRI）、正电子发射断层扫描（PET）以及超声检查（US）等，但使用CT数据可获得最高质量的图像，并且CT图像现在是3D模拟和导航图像最常用的数据来源。如果二维源图像质量不佳，那么在软件中进行再多的3D图像处理也无法得到高质量的3D图像。在本次展览中，重点展示了CT成像技术以及肝胆胰异常的3D可视化方面的最新进展，包括扫描和图像重建技术、对比增强技术、先进CT扫描技术的新应用以及新的虚拟现实模拟和导航成像。
