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)
Healthcare is a major candidate for improvement in any vision of the kinds of 'information highways' and 'information societies' that are now being visualized. The medical information management market is one of the largest and fastest growing segments of the healthcare device industry. The expected revenue by the year 2000 is US$21 billion. Telemedicine(More)
Chronic heart failure (CHF) is a complex cardiovascular syndrome whose management requires a complex clinical program involving, at different levels, several care stakeholders and the integration and interpretation of a number of diagnostic data and information. Within the EU FP6 project HEARTFAID (www.heartfaid.org), an integrated platform of services is(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)
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)
Since the population of elderly people grows absolutely and in relation to the overall population in the world, the improvement of the quality of life of elderly people at home is of a great importance. This can be achieved through the development of generic technologies for managing their domestic ambient environment consisting of medical sensors,(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)
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)
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)
