Hitachi Holds Ceremony to Mark Beginning of Proton Beam Therapy System Installation at Mayo Clinic

Rochester, MINN, May 30, 2013 - Hitachi, Ltd. today held a traditional Japanese blessing ceremony to mark the start of installation of a proton beam therapy (PBT) system at the new Richard O. Jacobson Building at Mayo Clinic in Rochester Minnesota.

The installation is the first of two PBT systems that Hitachi will supply to Mayo Clinic. A second system is scheduled to be installed at Mayo Clinic in Phoenix this fall. Patient treatment using PBT is expected to be available at the two facilities starting in the summer of 2015 and spring 2016, respectively.

Since the 1990’s, interest in proton beam therapy has grown in the U.S. as patients seek for more precise and less harmful radiation oncology treatment options.
