中文摘要 | 本研究主要建立一個具可攜式特性之非侵入式的紅外線手指血管電腦斷層影像系統。主要利用手指末端血管可被紅外線波長光線穿透的特性來觀察血管影像的變化;同時配合步進馬達精準的角度特性來完成不同角度之連續拍攝手指血管影像之系統,最後將連續拍攝的影像利用反投影原理重建成 2D 影像及 3D 影像。本實驗結果顯示,我們所提出的方法運用在假體的部份是具有可行性的,但目前不適合運用在人體手指血管辨識部分。 |
英文摘要 | This study is major aimed to establish a portable non-invasion type infrared imaging system for finger blood vessels. The proposed system uses infrared transmission to capture finger vessel patterns. For accuracy, a stepping motor was used to continuously record finger blood vessel images from different angles, and then the images were reconstructed into serial 2D and 3D images using the back projection principle. The results show that the proposed method is feasible for phantom verification, but distortions exist between the human finger and the corresponding reconstructed images. In conclusion, the preliminary results indicate that the infrared technique and back projection algorithm are useful, but need further development. |
