- Item3G Networks in Emergency Telemedicine - An In-Depth Evaluation And Analysis.(2007-02-06) Perakis, Konstantinos; Konnis, Georgios; Koutsouris, Dimitris; Banitsas, KonstantinosThe evolution of telecommunications technologies in connection with the robustness and the fidelity these new systems provide have opened up many new horizons as regards the provision of healthcare and the quality of service from the side of the experts to that of the patients The purpose of this paper is to evaluate the third generation telecommunications systems that are only recently being deployed in Europe as well as argue on why a transition from 2G and 2 5G to 3G telecommunications systems could prove to be crucial especially in relation to emergency telemedicine The experimental results of the use of these systems are analyzed the implementation of a tele consultation unit is presented and their exploitation capabilities are explored
- ItemMobile consultant: evaluation of additional services.(2007-11-16) Banitsas, Konstantinos; Georgiadis, Pantelis; Tachakra, Sapal; Cavouras, DionisisAs the need for mobility in the medical world increases newer systems and applications came to light many of them based on wireless and mobile networks PDA based systems were presented in the past capable of videoconferencing and transmitting high quality images between a roaming consultant and a fixed point in the hospital These systems not only had desirable characteristics but also incorporated additional services that were found of value paging Voice over IP calling Internet email intranet patient record update etc This paper presents an engineering and clinical evaluation of those additional services based on both objective and subjective criteria It concludes that such complementary services can be desirable as they increase personnel mobility utilize the hospital resources more efficiently while at the same time increase productivity and decrease the cost of hardware and communications
- ItemUsing HSPA to improve the telemedical links on a moving ambulance.(2009-02-16) Banitsas, Konstantinos; Tachakra, Sapal; Stefanidis, Euclid; Boletis, KonstantinosAs the demand for faster and more effective health care increases there is a growing need to establish mobile high speed communications between a moving ambulance and a consultation point usually a hospital The recent addition of HSPA HSDPA and HSUPA into the UMTS suite provides higher bandwidth and reduced delays making this choice ideal for real time telemedical applications In this paper we will describe a set of scenarios that took place in a typical large city area along with their equivalent results a moving ambulance was linked with a consultation station using HSPA and several videoconferencing sessions were initiated Best case worst case and average scenarios were recorded Furthermore in areas where the UMTS reception was marginal a repeater was placed on top of the vehicle to boost up the signal power and thus maintain the higher bandwidth Finally treating doctors were asked to evaluate the effectiveness of this system s outputs based on a variety of objective and subjective criteria
