Mobile telephony's technical and market success in Europe attracted researchers' interest in mobile systems. Some researchers began investigating appropriate architectures for providing information services to cellular mobile telephony users, and the quest for the "killer" third-generation (3G) mobile telephony application dominated the EU Information(More)
Telemedicine creates virtual medical collaborative environments. We propose here a novel concept of virtual medical devices (VMD) for telemedical applications. VMDs provide different views on biomedical recordings and efficient signal analysis. In this paper we present a telemedical EEG analysis environment based on virtual reality technologies. The same(More)
A simplified three-dimensional Monte Carlo simulation model of in vitro tumor growth and response to fractionated radiotherapeutic schemes is presented in this paper. The paper aims at both the optimization of radiotherapy and the provision of insight into the biological mechanisms involved in tumor development. The basics of the modeling philosophy of(More)
Telemedicine can be used to create virtual environments for the collaboration of patient, physicians, and medical staff. Multi modal presentation is increasingly used to improve human-computer interface. In this paper we present a multimodal interactive environment for EEG/MEG data presentation based on Internet technologies and a virtual reality user(More)
Self care is a recent initiative by the Department of Health in the UK that aims to treat patients with long-term conditions sooner, nearer to home and earlier in the course of their disease. To this end, it places the point-of-care in the community and often at the patients' own home. In this paper we discuss the building blocks of pervasive self care, a(More)
– An advantageous aspect of telemedicine is that it can create virtual environments for collaboration between patient, physicians, and medical staft. In this paper we present a multimodal interactive environment for EEG/MEG data presentation based on a virtual reality user interface (VRUI). In addition, to visualization, the VRUI uses sonification. The(More)
This paper considers the problem of ventricular segmentation and visualisation from dynamic (4D) MR cardiac data covering an entire patient cardiac cycle, in a format that is compatible with the web. Four different methods are evaluated for the process of segmentation of the objects of interest: The K-means clustering algorithm, the fuzzy K-means (FKM)(More)
During the last decade, the size of elderly population has shown remarkable growth, especially in the developed countries of Europe. Main reason for this phenomenon is the improvement of the conditions of daily life at home and work, assisted by the socio-economic progression, best quality private living environments and the enormous development in medicine(More)
