The Human Communication Technologies (HCT) and Robotics and Controls Laboratories are currently in need of a 3D scanner to support four primary research directions: development of a digital workflow for improving oral reconstructive surgery, new interaction paradigms for a 3D perspective corrected spherical display (3DPS), novel ultrasound interfaces and creating human tissue phantoms. In our research on oral reconstructive surgery, we are designing a subject-specific mastication model, called the virtual articulator, based on clinical data such as 3D digital surface scans and trajectory of jaw movements. This mastication model will be used in a digital computer aided design and manufacturing (CAD/CAM) treatment workflow to enable prediction of functional outcomes such as post-treatment ability to chew. Due to the sensitivity of this clinical application, the 3D scans must have an accuracy of <20 µm. Additionally, our research on new interaction methods to support a ‘capture-modify-make’ paradigm for CAD/CAM using a 3D perspective corrected display also requires a 3D scanner with colour texture information as well as good precision. The third project is part of our ongoing effort to redesign the ultrasound (US) probe to provide customized probe and medical instrument guides to enable better positioning. Relatedly, we also need to scan the curves of the human body where the US transducer will be used so that we can create phantoms to mimic the curves of the human body to better test our new configurations. We have 18 graduate students that have an immediate need for regular use of this 3D scanner as part of their research programs. An additional 8-20 students will immediately use it sporadically. Previously we have taken advantage of a high precision Coordinate Measuring Machine (CMM), which is part of a Composites Research Network lab at UBC; it is now impractical to continue using this scanner due to cost, speed and scheduling for regular use. Thus, we have requested CA$44,576 to purchase a Gomeasure3D LMI3D scanner with Macro Lens and Calibration kit with DSLR option for colour texture capturing.

人类通信技术 (HCT) 和机器人与控制实验室目前需要一台 3D 扫描仪来支持四个主要研究方向：开发用于改进口腔重建手术的数字工作流程、3D 透视校正球形显示器 (3DPS) 的新交互范例）、新颖的超声接口和创建人体组织模型在口腔重建手术的研究中，我们正在根据临床数据（例如，虚拟咬合架）设计一种特定于受试者的咀嚼模型。该咀嚼模型将用于数字计算机辅助设计和制造 (CAD/CAM) 治疗工作流程，以预测治疗后的咀嚼能力等功能结果。对于该临床应用，3D 扫描的精度必须小于 20 µm 此外，我们对使用 3D 透视校正显示器支持 CAD/CAM 的“捕获-修改-制作”范式的新交互方法的研究也需要具有颜色纹理信息和良好精度的 3D 扫描仪是我们不断重新设计超声波（美国）探头以提供定制探头和医疗器械指南以实现更好定位的一部分。我们有 18 名研究生迫切需要定期使用这款 3D 扫描仪。作为另有 8-20 名学生会立即使用它，之前我们曾使用过高精度坐标测量机 (CMM)，它是 UBC 复合材料研究网络实验室的一部分，但现在已不切实际了。由于成本、速度和定期使用的安排，我们需要继续使用该扫描仪，因此，我们请求 44,576 加元购买带有微距镜头和校准套件的 Gomeasure3D LMI3D 扫描仪。用于色彩纹理捕捉的 DSLR 选项。
