Increasingly，however，remote diagnosis(遠程診斷) will be based on real physiological data(生理數(shù)據(jù)) from the actual patient.

Bandwidth(寬帶) is the limiting factor for sending complex(復(fù)雜的) medical pictures around the world—CT photos being one of the biggest bandwidth users.

But medicine is looking towards both the second-generation Internet and third-generation mobile phones for the future of remote medical service.,Doctors have met to discuss computer-based tools for medical diagnosis，training and telemedicine. With the falling price of broadband communications，the new technologies should start a new time when telemedicine and the sharing of medical information，experts’ opinions and diagnosis are common. 本文主要講述人們將來可以通過網(wǎng)上看病，醫(yī)生可以根據(jù)病人的生理數(shù)據(jù)做出遠程診斷。隨著第二代因特網(wǎng)和第三代移動手機為將來的遠程醫(yī)療服務(wù)，尤其是寬帶網(wǎng)交流價格的下降，遠程醫(yī)療和醫(yī)藥信息、專家意見和診斷共享將成為家常便飯。,6.
