Development of Internet Based Remote Health and Activity Monitoring Systems for the Elders

電腦輔助手術(Computer Aided Surgery; CAS)技術近年來已成為各先進國家醫療工程研究之重要課題及發展重點。其中，『手術導航系統』更是電腦輔助手術應用系統之成功關鍵。本文將針對小耳症病患肋骨重建手術(Retained Auricular Prosthesis Surgery)，開發一套3D立體定位導航系統。本系統包括3D定位手臂(3D Digitizer Arm)、空間座標量測與轉換模組、音頻導引模組(Sound-Guided Navigation Module)等。其中3D定位手臂具有五個自由度，可供病患手術部位座標量測，進而與病患電腦斷層影像立體重建模型座標比對，推導座標轉換矩陣作為病患術中導航之即時運算基準。另外，本系統具有音頻導引模組，可透過不同之音調(Audio Tone)與間歇頻率(Intermittence Frequency)，提供外科醫師即時導引訊息，以便精確地找到術前手術規劃之植入點。最後，本文也介紹臨床應用之案例，經實際臨床驗證，此系統可有效協助醫師進行植入點之準確定位與導引，也可使手術時間縮短，提高外科手術之品質。

Computer aided surgery (CAS) had been an important research topic in recent years. 3D navigation is the crucial technique in the CAS applications. In this paper, a sound-guided 3D navigation system used for the retained auricular prosthesis surgery wad developed. This system consists of a 3D digitizer arm, a 3D space coordinate transformation module and a sound-guided navigation module. A 3D digitizer is a 5 degree-of-freedom passive robotic arm, and it is used to measure the coordinates of the registration and implant landmarks of the patient. The measured coordinates of landmarks are further compared with the patient's 3D reconstruction computer model that is constructed in terms of the computed tomography (CT) images to calculate the coordinate transformation matrix. The transformed implant coordinates are desired for the real-time navigations. In addition, the proposed sound-guided navigation module provides the real-time surgical guidance based on different audio tones and intermittence frequencies to improve the surgical accuracy. Finally, a clinical study of the retained auricular prosthesis surgery is introduced in this paper. Based on the results of the clinical validation, the proposed system effectively assistants the surgeon to increase the surgical quality and reduce the surgical time as well.
