| dc.description.abstract | 現今電腦斷層(Computed Tomography, CT )影像於臨床診斷之應用已相當廣泛，一組序列式CT影像能夠提供病患身體的真實三維狀況，但受限於目前硬體顯示介面，僅能將三維影像轉換為二維才能夠由二維螢幕輸出並顯示。雖然三維成像的影像已可以提供給使用者大略的立體感，但對於醫學領域的使用仍稍嫌不足，不足的主因是無法給予使用者真實的立體感。本研究之研究針對CT影像的顯示，利用立體渲染法將其重建為三維影像，並配合虛擬實境的原理以及搭配立體顯像設備，將傳統的2D醫學影像以3D立體的方式呈現；再針對不同的硬體設備包含資訊手套和空間定位裝置做性能測試，並配合空間定位技術以及相對應的人機介面，共同搭配組合成不同的功用，建構出一套基本的醫療用虛擬實境互動系統，並應用於不同的術前評估範例當中，分別為腦血管病變範例以及骨盆骨折範例。

| dc.description.abstract | Computed Tomography (CT) technology has been extensively used in daily clinical diagnosis as it can provide a series of 2D scans of the human body. However, due to the limitation of cheaper but efficient PC-based software, current diagnosis of CT images is always performed in terms of two-dimensional display. Although three-dimensional imaging technology is available and can offer more realistic display of the images, it is still insufficient for medical applications as the display is still in a two-dimensional mode. The purpose of this study is to develop a human-machine interface for medical virtual reality. We employ volume rendering and stereo display techniques for the display of medical images in a stereo manner. We also integrate data glove and six DOF positioning tracker for providing a virtual reality system for medical applications. We intend to integrate such devices into our software and develop appropriate human-machine interface so that we can manipulate real and virtual objects together. We employ this system to cerebrovascular disease diagnosis and preoperative evaluation of pelvic fracture for demonstrating its capability.
