Abstract: Remote teleconsultation by specialists is important for timely, correct, and specialized emergency surgical and medical decision making. In this paper, a PDAphonebased instant remote teleconsultation system is designed by combining wireless communication with WiFi interfaced local wireless links and 3G wireless communication technology. This system can provide a more effective means of emergency teleconsultation without requiring the user to be limited to a fixed location. Moreover, it enables synchronized radiological image sharing between the attending physician in the emergency room and the remote specialist on picture archiving and communication system terminals without distorted image acquisition. To enable rapid and finequality radiological image transmission over a cellular network in a secure manner, progressive compression and security mechanisms are incorporated. This system may be critical in increasing patients’ chances of survival, and have a practical significance.
