摘要

遠距醫療相關概念之應用已有50年的歷史；因為人們對醫療行為之既有觀念，相關醫療法規之限制以及過去之通訊技術以及軟硬體設備之環境，至今能未能成為普及應用。因此，本研究以視訊會議之概念為基礎，整合遠距生理訊號之監控，並以普及之電腦與周邊設備，實現一個遠距問診所需之軟體架構。系統實現之架構中，包含以Microsoft DirectShow為核心之即時影音之雙向傳輸程序，以提供遠距醫生與病人之間之互動通信，並以MIT生理訊號資料庫之ECG資料作為生理訊號監控之該念整合,以為遠端之ECG即時監控之運用。
本系統可在10/100Mbps之以太網路上穩定進行320*240 pixel，25 fps之未壓縮的雙向即時影像通訊，以及取樣率為44.1k Hz，解析度16bit 之WAVE格式即時聲音訊號之傳輸。影音擷取的機制乃以DirectShow為核心，其本身之特性(COM )之模組化能力，其對相關影音編碼機制有著靈活的擴充性。即時之心電圖監視，乃以MIT ECG Database之360Hz/12bit 的ECG樣本為模擬訊號來源，在雙向影音通訊的同時，同步對遠端之ECG波形監視。
本研究所實現之架構，可作為相關互動影音通信、常用生理訊號之遠距傳輸、監控之遠距健康照護、問診等遠距醫療應用之發展基礎。

The concept of Tele-medicine has emerged since (for example late 1950) and it has been evolving into a real-world application nowadays. Nevertheless, Tele-medicine is still facing a number of challenges on multiple fronts. In major society, patient-doctor direct consultation is still considered as the best health treatment method. Tele-medicine development is also hindered by a lack of regulation standards in medical area. Communication technology, as backbone for Tele-medicine was not as sophisticated as recent time. Those three factors are perceived to constraint the development and implementation of Tele-medicine system.
Tele-consultation system, as one of the supporting elements of Tele-medicine has been designed and implemented to demonstrate the basic, general purpose Tele-medicine system.
There are two functions integrated in the system. The first function is remote real-time ECG monitor. The second function is the bi-directional audio and video transmission. The implementation of the framework is based on the Microsoft DirectShow environment. The MIT ECG database is utilized to simulate ECG signal on the patient-side.
The system can transfer the bi-directional video through Ethernet 10/100 Mbps network with 320 x 240 pixel resolution without particular coding algorithm. The frame rate can be up to 25 fps. The audio is transmitted using 44.1 kHz sample rate with 16 bit resolution per sample. The remote side can monitor the ECG signal at 360 Hz rate and 11 bit resolution synchronously.
The system can provide the basic form of the bi-directional video transmission and general remote bio-signal monitor as foundation for Tele-healthcare and Tele-consultation applications.
