The World Congress 2009 for Medical Physics and Biomedical Engineering is being organized by:
- IUPESM – The International Union for Physical and Engineering Sciences in Medicine incorporating the IFMBE and IOMP, represents more than 140,000 biomedical engineers and medical physicists and operates under the principal objective to advance sciences in medicine for the benefit and well being of humanity.
- IOMP – The International Organization for Medical Physics represents over 16,500 medical physicists worldwide and 76 national member organizations.
- IFMBE – The International Federation for Medical and Biological Engineering is primarily a federation of national and transnational organizations. The Federation has an estimated 120,000 members in 58 affiliated organizations.
- DGMP – The German Society for Medical Physics was founded 1969 and represents about 1,200 members working in science, industry and hospitals. Several regional sections of the Society have been established in recent years to improve communication channels among medical physicists in Germany and to support educational measures.
- DGBMT – German scientists in the field of biomedical engineering are organized in the DGBMT, which was founded in 1972. The Society merged with the VDE in 2001 and now has about 1,900 members including physicians, engineers, scientists and companies.
- EFOMP - The European Federation of Organizations in Medical Physics was founded in 1980. The current membership covers 35 national organizations which together represent more than 5,000 physicists and engineers in the field of medical physics.
- VDE – The VDE Association for Electrical, Electronic & Information Technologies has over 34,000 members, including a broad spectrum of engineers, scientists and technicians, some 7,000 students and around 1,250 corporate and institutional members.
