立體醫學影像表面的產生,是指由一系列二維的醫學影像產生三維的立體醫學影像並呈現在電腦螢幕上,而使用者亦能透過電腦對此立體醫學影像進行相關操作。
重建後的立體醫學影像,其影像品質會因三維重建技術的不同而有所差異。本項研究即提出一套三維重建演算法,在正確與快速的前提下建立出影像品質較佳之立體醫學影像。
除此之外,以此三維重建演算法重建的立體醫學影像,亦結合體素圖像與多邊形表面圖像之優點,前者完整保有三維物件內部資訊;後者在呈現上則提供較佳之影像品質。故於應用上,使用者在對此立體醫學影像進行相關操作時有更大的彈性與更快的反應時間。
Surface generation of 3D medical images uses a series of 2D images to rebuild the 3D objects. Users can manipulate the 3D objects generated by the computer.
The quality of rebuilt 3D medical objects will be different upon the 3D reconstruction methods. This paper presents a faster and more accurate reconstruction method to gain better quality of the 3D objects.
We also integrate the advantage of voxel based images and surface based images. The voxel based images hold entire information inside the 3D objects, and the surface based images provide better image quality. In the aspect of application, this reconstruction method provides faster response time and more extensions when users manipulate the 3D objects.
