About IFMBE
The International Federation for Medical and Biological Engineering (IFMBE) was established in 1959 to provide medical
and biological engineering with a vehicle for international collaboration in research and practice of the profession. The Fed-
eration has a long history of encouraging and promoting international cooperation and collaboration in the use of science and
engineering for improving health and quality of life.
The IFMBE is an organization with membership of national and transnational societies and an International Academy. At
present there are 52 national members and 5 transnational members representing a total membership in excess of 120 000
worldwide. An observer category is provided to groups or organizations considering formal affiliation. Personal membership
is possible for individuals living in countries without a member society The International Academy includes individuals who
have been recognized by the IFMBE for their outstanding contributions to biomedical engineering.
Objectives
The objectives of the International Federation for Medical and Biological Engineering are scientific, technological, literary,
and educational. Within the field of medical, clinical and biological engineering it’s aims are to encourage research and the
application of knowledge, and to disseminate information and promote collaboration.
In pursuit of these aims the Federation engages in the following activities: sponsorship of national and international meet-
ings, publication of official journals, cooperation with other societies and organizations, appointment of commissions on
special problems, awarding of prizes and distinctions, establishment of professional standards and ethics within the field, as
well as other activities which in the opinion of the General Assembly or the Administrative Council would further the cause
of medical, clinical or biological engineering. It promotes the formation of regional, national, international or specialized
societies, groups or boards, the coordination of bibliographic or informational services and the improvement of standards in
terminology, equipment, methods and safety practices, and the delivery of health care.
The Federation works to promote improved communication and understanding in the world community of engineering,
medicine and biology.
Activities
Publications of IFMBE include: the journal Medical and Biological Engineering and Computing, the electronic magazine
IFMBE News, and the Book Series on Biomedical Engineering. In cooperation with its international and regional confer-
ences, IFMBE also publishes the IFMBE Proceedings Series. All publications of the IFMBE are published by Springer Ver-
lag. The Federation has two divisions: Clinical Engineering and Health Care Technology Assessment.
Every three years the IFMBE holds a World Congress on Medical Physics and Biomedical Engineering, organized in co-
operation with the IOMP and the IUPESM. In addition, annual, milestone and regional conferences are organized in different
regions of the world, such as Asia Pacific, Europe, the Nordic-Baltic and Mediterranean regions, Africa and Latin America.
The administrative council of the IFMBE meets once a year and is the steering body for the IFMBE: The council is sub-
ject to the rulings of the General Assembly, which meets every three years.
Information on the activities of the IFMBE can be found on the web site at: http://www.ifmbe.org.
Foreword
It is our great pleasure to welcome you at the11th Mediterranean Conference on Medical and Biological Engineering and
Computing – the MEDICON 2007. After 24 years MEDICON conference is coming back to Slovenia, this time into its capi-
tal – Ljubljana. The MEDICON conferences are international events of high scientific standards with long lasting tradition
held every third year in one of the Mediterranean countries under the auspices of the International Federation for Medical
and Biological Engineering.
Biomedical engineering today is a well-recognized area of research. It brings together bright minds from diverse disci-
plines ranging from engineering, physics, and computer sciences on one side to biology and medicine on the other side. With
valuable assistance of members of the International Advisory Committee and Scientific Program Committee, the co-
organizing institutions and societies, our sponsors, and distinguished invited lecturers we will ensure that the research and
development presented at MEDICON 2007 plenary meetings, scientific sessions, and workshops will truly be relevant and
up-to-date.
MEDICON 2007 is taking place at the premises of University of Ljubljana, Faculty of Electrical Engineering. The choice
was obvious: Ljubljana is accessible and vivid, and the academic environment is familiar to all of us. As Ljubljana is located
in the centre of the country it offers an excellent opportunity also to explore on your own the remarkable variety of Slove-
nia’s scenery and national heritage. The Mediterranean coast of Primorska, Alpine resorts of Gorenjska, lovely hills and
primeval forests of Dolenjska and the far-reaching plains of Prekmurje are just few examples of regional diversity you can
encounter here. All these and other regions of Slovenia are easily accessible from Ljubljana within two hours of driving. We
will visit some of our jewels together: Bled and Postojna.
We feel confident that you will enjoy MEDICON 2007 both scientifically and socially. We will make every effort to
make MEDICON 2007 a memorable event. This is also the place where you will meet your old friends and make new ones.
Together we will all face new challenges imposed to us by our society and new technologies. We look forward to meeting
you all in Ljubljana.
