| Summary: | 碩士 === 中原大學 === 醫學工程研究所 === 96 === 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.
