Acknowledgment

The 2011 Nuclear Science Symposium, Medical Imaging Conference, and Room Temperature Semiconductor Detector Workshop would not be possible without the many hours of hard work contributed by the Organizing Committee and the numerous volunteers who graciously offered their time. The organization of an IEEE meeting outside the US presents some unique challenges, and the committee has done a superb job in resolving the issues smoothly so as to make the conference a scientific, social, and financial success. As General Chair, it has been a pleasure working with such an outstanding team and I thank them sincerely for the enriching experience. It has been especially rewarding working with my friends and colleagues from Spain and to have had the opportunity to make several visits to the beautiful city of Valencia. It should be remembered that the conference is made possible through the sponsorship of the IEEE Nuclear and Plasma Sciences Society (NPSS) and the generous support of the cooperating institutions and organizations listed in this program book and throughout the conference venue. The support from Spanish institutions has been especially encouraging. Following the submission of a record number of abstracts in all categories, the Scientific Program Chairs performed an outstanding and timely job in assembling the contributed papers so as to maximize the benefit to the attendees. I sincerely thank all the Program Chairs for their efforts.
