中文摘要 | 外科醫師的教育及訓練耗時,因少有機會去對病 忠做練習。因此我們提出一低價、全球資訊網上可廣 被使用的分散虛擬實境架構。在此架構,從伺服器下 載的網頁驅動顧客端的虛擬實境用輸出輸入裝置,讓 使用者能浸於虛擬環境中。這有別於傳統的伺服器需 負責大部分工作及裝置的方法。為實現這構想,我們 用全球資訊網這媒介驅動顧客端的裝置。我們著眼於 以容積為基礎的手術模擬應用,這通常被認為需大量 計算及使用高價電腦。但我們系統使用個人電腦及全 球資訊網去達到分散虛擬環境的目的。本論文介紹手 術模擬、同質面重建及立體顯像的演算法,和伺服器 與顧客端合作的方法,也展示一個骨絡肌肉的手術模 派例o |
英文摘要 | Educating and training a surgeon requires much time because a surgeon has few opportu nities to rehearsal surgical modalities on patients. This study proposes a low-cost and widelyavailable distributed VR architecture via the WWW to solve this problem. In this architecture, Web pages from the server drive VR 1/0 devices on c1ientsto enable users to immerse in a virtual environment. This process is different from the conventional approach that the server is responsible for most works and devices. Methods of driving the devices on c1ientsand being called by the Web page are introduced herein. This paper focuses on the application of volume based surgical simulations that is usual1y considered involving much computation and expen sive workstations. A system that uses PC platforms and the Wv..T media was built to support the distributed VR surgical simulation. This paper introduces the algorithms for surgical simulation, isosurface reconstruction and rendition, and the methods by which c1ientscan co operate with the server. A simulation example of musculoskeletal surgery is present. |
