The 2013 ICME International Conference on Complex Medical Engineering (CME 2013) will take place in Beijing, China from May 25 to May 28, 2013. Beijing is both a tribute to China's proud history and a gateway to China's future. The capital city during the Liao, Yuan, Ming and Qing Dynasties, Beijing has long been the political, cultural, and diplomatic center of China. It is now an international metropolis, home to 11 million people from all walks of life. As the host city of CME 2013, Beijing not only provides the attendees with a great venue for this event, but also an unparalleled experience in Chinese history and culture. You are cordially invited to join us at CME 2013 in Beijing to live this unique experience. The objective of CME 2013 is to provide a forum for researchers, educators, engineers, and government officials involved in the general areas of biomedical engineering to disseminate their latest research results and exchange views on the future research directions of these fields.
