关于客户
本案例研究中的客户是加利福尼亚州拉霍亚斯克里普斯诊所的希利骨科研究和教育中心 (SCORE)。 SCORE 是一家致力于推进骨科研究和教育领域的著名机构。他们特别专注于提高对骨科植入物的理解和设计，最终目标是提高退行性关节疾病患者的生活质量。他们的工作涉及复杂的生物力学建模和分析，为此他们依赖先进的软件工具。
挑战
斯克里普斯诊所的希利骨科研究和教育中心 (SCORE) 面临着提高对骨科植入物（特别是肩关节置换术）的理解和设计的挑战。现有的植入物通常由钛合金制成并内衬塑料，预计使用寿命不会超过 20 年，因此不适合 65 岁以下的患者。此外，患者经常担心植入物的活动范围、力量恢复和寿命。新的联合。半月板（一种新月形的膝盖软骨）替代物的建模过程也是一项复杂且耗时的任务，需要团队每次想要改变曲率或厚度时从头开始建模过程。
解决方案
SCORE 利用 Altair HyperWorks 软件工具来增强他们对关节置换所涉及的生物力学的理解。他们使用 Mimics 3D 图像处理软件将患者肩部的 CT 图像切片合并到 3D 体积中，并导出骨骼表面。使用 HyperMesh，该团队从患者肩部模型中移除了患病的骨头，并用植入物（包括将其固定到位的水泥）代替。这有助于外科医生为每位患者选择最佳的种植体产品并改进他们的手术技术。为了对半月板进行建模，该团队首先从 MRI 扫描中分割出患者半月板的 3D 图像，然后使用 HyperMesh 构建整个膝盖的有限元分析模型。他们使用网格变形来调整参数，以确定变化如何影响接触应力。 D'Lima 博士还使用 Altair OptiStruct 来模拟应力窗口，这是影响种植体寿命的关键因素。

IoT platform Enables Safety Solutions for U.S. School Districts
Designed to alert drivers when schoolchildren are present, especially in low-visibility conditions, school-zone flasher signals are typically updated manually at each school. The switching is based on the school calendar and manually changed when an unexpected early dismissal occurs, as in the case of a weather-event altering the normal schedule. The process to reprogram the flashers requires a significant effort by school district personnel to implement due to the large number of warning flashers installed across an entire school district.

Digital Transformation of Atlanta Grout & Tile: An IoT Case Study
Atlanta Grout & Tile, a Tile, Stone & Grout restoration company based in Woodstock, Georgia, was facing challenges with its traditional business model. Despite steady growth over the years, the company was falling behind the web revolution and missing out on the opportunity to tap into a new consumer base. They were using independent software from different vendors for each of their department information and workforce management. This resulted in a lot of manual work on excel and the need to export/import data between different systems. This not only increased overhead costs but also slowed down their response to clients. The company also had to prepare numerous reports manually and lacked access to customer trends for effective business decision-making.

Revolutionizing Medical Training in India: GSL Smart Lab and the LAP Mentor
The GSL SMART Lab, a collective effort of the GSL College of Medicine and the GSL College of Nursing and Health Science, was facing a challenge in providing superior training to healthcare professionals. As clinical medicine was becoming more focused on patient safety and quality of care, the need for medical simulation to bridge the educational gap between the classroom and the clinical environment was becoming increasingly apparent. Dr. Sandeep Ganni, the director of the GSL SMART Lab, envisioned a world-class surgical and medical training center where physicians and healthcare professionals could learn skills through simulation training. He was looking for different simulators for different specialties to provide both basic and advanced simulation training. For laparoscopic surgery, he was interested in a high fidelity simulator that could provide basic surgical and suturing skills training for international accreditation as well as specific hands-on training in complex laparoscopic procedures for practicing physicians in India.

Implementing Robotic Surgery Training Simulator for Enhanced Surgical Proficiency
Fundacio Puigvert, a leading European medical center specializing in Urology, Nephrology, and Andrology, faced a significant challenge in training its surgical residents. The institution recognized the need for a more standardized and comprehensive training curriculum, particularly in the area of robotic surgery. The challenge was underscored by two independent studies showing that less than 5% of residents in Italian and German residency programs could perform major or complex procedures by the end of their residency. The institution sought to establish a virtual reality simulation lab that would include endourological, laparoscopic, and robotic platforms. However, they needed a simulator that could replicate both the hardware and software of the robotic Da Vinci console used in the operating room, without being connected to the actual physical console. They also required a system that could provide both basic and advanced simulation training, and a metrics system to assess the proficiency of the trainees before they performed surgical procedures in the operating theater.
