Dr. Mitsuhiro Nakamura is an associate professor at Kyoto University, Kyoto, Japan.
Dr. Nakamura’s early work during the four years of his doctoral course – completed at Kyoto University in 2010 – focused on four-dimensional imaging and delivery in radiation therapy for moving tumors. He investigated physical and clinical aspects of four-dimensional computed-tomography. During this work, he developed a visual feedback system, and clinically applied this system to intensity-modulated radiotherapy in combination with breath holding at end-exhalation. This technique was used in a phase I dose-escalation study that showed a significant improvement in the median and 2-year overall survival of patients with locally advanced pancreatic cancer. Thus, this work has made a substantial contribution to improving patient outcomes.

Dr. Nakamura considers that his most meaningful contribution to date has been in the development and clinical application of the Vero system, a radiotherapy unit with an integrated real-time tumor tracking system developed by Mitsubishi Heavy Industries, Ltd., in collaboration with Kyoto University.
Vero is a gimbaled–head radiotherapy device whose unique structure with multi-image-guided radiation therapy functions has initiated two new treatment modalities, such as real-time tumor tracking radiotherapy and Dynamic WaveArc therapy.
Dr. Nakamura has played a central role in the medical physics-related development of these advances.

Among other work, Dr. Nakamura is a member of the Japanese Clinical Oncology Group (JCOG) Radiotherapy Committee, in which role he recently contributed to the development of an on-site dosimetry audit system to support quality assurance in clinical outcomes of JCOG clinical trials.

Internationally, Dr. Nakamura’s academic achievements are attested by his participation in the Global Quality Assurance of Radiation Therapy Clinical Trials Harmonisation Group and a number of other international research collaborations, including projects with Prof. Keall et al and Prof. Verellen et al.

To date, Dr. Nakamura has authored 9 book chapters. He has coauthored 101 papers in the peer-reviewed English literature, 15 as first author and 45 as corresponding author.

Head of Hyperpolarization Research Freiburg,
University Medical Center Freiburg, Germany

Dr. Jan-Bernd Hövener was born in Münster (Westfalen), Germany, and studied Physics and Business Informatics at the “Westfälische Willhlems Universität” in Münster. After receiving his Vordiplom (intermediate diploma) in 2001, he moved on to the University of Heidelberg. He spend two semesters abroad in France at the “Université Nice Sophia Antipolis”, where he took part in the “Maîtrise Physique” and “DESS biomedical”, including subjects on fluid dynamics and statistical physics.

After returning to Heidelberg, he finished the final exams and carried out his diploma thesis with Prof. Bachert at German Cancer Research Center (DKFZ) entitled “Development of a technique to determine non-invasively the total content of N-Acetly-L-Aspartate in the human brain in vivo”. This work was the starting point for a joint research project with Prof. Gass (Mannheim) and Prof. Gonen (New York). In the course of this project, Dr. Hövener spend several month followed by multiple visits as a visiting scientist in the lab of Prof. Gonen at New York University (NYU).

For his PhD, Dr. Hövener decided to join the hyperpolarization research group at the California Institute of Technology (CalTech, Prof. Weitekamp), and the Huntington Medical Research Institutes (HMRI, Profs. Bhattacharya and Ross), both in Pasadena, USA, for two years. Upon his return to Germany, he defended his thesis after total time of two years and seven month with the mark “magna cum laude” (very good) at the University of Heidelberg, Faculty of Physics and Astronomy.

During this time, he contributed essentially to the development and application of parahydrogen-based hyperpolarization of biomolecules, which is reflected by several manuscripts, conference contributions and awards.

Building on the existing contacts, Dr. Hövener was invited by Prof. Hennig in 2009 to implement an entirely new hyperpolarization program in Freiburg. In the same year, the concept of this endeavour was voted “best talk” at the Annual Meeting of the Int. Society of Magnetic Resonance in Medicine (ISMRM), German Chapter, in Basel, Switzerland.

In 2010, Dr. Hövener was admitted to the Academy of Excellence of the German Science Foundation (DFG). Supported by this award, Dr. Hövener was able to expand his group and to date has supervised more than ten students, is teaching in Freiburg and has published more than 15 papers and numerous peer-reviewed or invited conference contributions. His standing in the scientific community is reflected by his election to the board of the ISMRM German Chapter and his function as reviewer for scientific journals and funding agencies (including e.g. Angewandte Chemie int. ed., e.g.).

The preliminary peak of work is represented by the discovery of the effect of continuous hyperpolarization, which was subject of several press releases and found a broad echo in the national news media. His future potential and past accomplishments were recognized by the admission to the Emmy-Noether Program (ENP) of the DFG. The ENP is awarded to internationally experienced scientists in order to accelerate the academic carrier towards scientific independence (> 1,000,000 €).

In his leisure time, Dr. Hövener teaches sailboat racing to children, organizes sailing camps and, time permitting, competes himself. He enjoys all sorts of water sports, mountain biking, running before or after work and swimming in the next lake.
