計算機圖學的一個主要醫學應用為提供手術模擬。肩峰成形手術治療主要目的是減少肩旋轉肌腱與肩峰間的摩擦碰撞,此手術可以增加肩關節活動度和去除活動能力受限制的原因,如去除骨贅使肱骨在肩峰下的活動空間增加,達到減壓的效果。在此過程中,此手術會修補被磨破的組織,如肩袖等。本論文對目前現有病患的肩關節資料先進行手術前之評估,並對目前病徵進行模擬骨贅切除、削磨。透過我們的方法協助外科醫師預先排練和驗證規劃關節手術。
A major application of computer graphics in medicine is to provide surgical simulations. The main purpose of acromioplasty is to reduce the friction and collision between the rotator cuff and the acromion. This surgery can increase the shoulder joint mobility and remove the reasons for limited the shoulder joint activity ability. For example, removing the spur can increase the activity space of the humerus under the acromion and achieve the effect of decompression. In the process, the surgery repairs the tear muscle tissue, such as the rotator cuff. We evaluate the current shoulder joint data of patients before surgery, and simulate the current symptoms for spur resection and burring. Through our method, surgeons can be assisted in pre-rehearsing and verify planned joint surgery.
