We hope you will join us, taking advantage of this opportunity to learn the latest advancements in the field, to reconnect with old friends and meet new ones, and to take in the sights and sounds of Seoul. WC 2006 offers a strong and diverse scientific program covering a wide range of issues and challenges that are currently present in Medical Physics and Biomedical Engineering on the theme of “Imaging the Future Medicine.” Approximately, 2,500 papers will be presented in oral and poster sessions on the 25 tracks covering around 250 sessions. In addition to the proffered presentations, you will have access to 15 symposium, 4 workshop, 15 short course and 15 continuing education course sponsored by AAPM during the congress. We have also invited numerous speakers from the world. 10 plenary speak- ers and more than 100 invited speakers will give us their perspective on the challenges and opportunities ahead for Medical Physics and Biomedical Engineering and their potential to contribute to improved health care throughout the world. In particular, we wish to extend sincere thanks to the track chairs, session chairs, international advisors and Scientific Pro- gram Committee members for their hard work and invaluable assistance performed on a voluntary basis in putting the con- gress together over the past year. We hope that you will have the opportunity to enjoy the rich heritages and dynamic lifestyle of Korea, and a productive and enjoyable time in Seoul, Korea. Best regards, Sun I.
