Series Editor: R. Magjarevic

The International Federation for Medical and Biological Engineering, IFMBE, is a federation of national and transnational organizations representing internationally the interests of medical and biological engineering and sciences. The IFMBE is a non-profit organization fostering the creation, dis-semination and application of medical and biological engineering knowledge and the management of technology for improved health and quality of life. Its activities include participation in the formulation of public policy and the dissemination of information through publications and forums. Within the field of medical, clinical, and biological engineering, IFMBE’s aims are to encourage research and the application of knowledge, and to disseminate information and promote collaboration. The objectives of the IFMBE are scientific, technological, literary, and educational.

The IFMBE is a WHO accredited NGO covering the full range of biomedical and clinical engineering, healthcare, healthcare technology and man-agement. It is representing through its 58 member societies some 120.000 professionals involved in the various issues of improved health and health care delivery.

Foreword

Projections for advances in medical and biological technology will transform medical care and treatment. This in great part is due to the result of the interaction and collaboration between medical sciences and engineering. These advances will result in substantial progress in health care and in the quality of life of the population.

Frequently however, the implications of technologies in terms of increasing recurrent costs, additional required support services, change in medical practice and training needs are underestimated. As a result, the widespread irrational use of tech-nologies leads to a wastage of scarce resources and weakens health systems performance. To avoid such problems, a system-atic and effective Health Technology System must be developed and introduced, requiring the support and commitment of decision makers of all levels of the health system.

The MediTech2009 conference aims to provide a special opportunity for the Romanian professionals involved in basic re-search, R&D, industry and medical applications to exchange their know-how and build up collaboration in one of the most human field of science and techniques. The conference is intended to be an international forum for researchers and practitio-ners interested in the advance in, and applications of biomedical engineering to exchange the latest research results and ideas in the areas covered by the topics (and not only!).

We believe the reader will find the proceedings an impressive document of progress to date in this rapidly changing field. The problems at hand are formidable and difficult, but with time not unsolvable. Those who participated in this conference represent some of the leading authorities in the field. Their presentations and discussions have pinpointed current thinking and new leads for future work.

All papers submitted for presentation went through a review process and were evaluated by two reviewers from 14 coun-tries (whose effort and hard work reflect their commitment and dedication to the profession). Those individuals whose pa-pers were chosen for presentation at the conference submitted manuscripts to be published in these Proceedings. We want to thank all those who submitted papers for review and those who provided manuscripts for publication in these proceedings.

Sincere appreciation and gratitude are expressed to the Scientific Advisory Committee and the cochairmen for their dili-gent efforts in effecting a most timely and provocative conference. To document the current thinking in such a publication is most important and should serve as a useful guide for others working in the field.

We also want to give a special thanks to Em.Univ.-Prof.Dipl.-Ing.Dr.techn. Helmut Hutten, the Honorary Chairman, for his efforts in promoting worldwide the Romanian National Society for Medical Engineering and Biological Technology and in promoting our international conference MediTech!
