Elekta / Mitsubishi Electric Collaboration Helps Japan’s Gunma University Heavy Ion Medical Center Launch Advanced Carbon Ion Therapy for Treating Cancer

Patient with prostate carcinoma is center’s first to benefit from high-energy treatment

Afghanistan — Sunday, May 16, 2010

Three years of teamwork between Elekta and Mitsubishi Electric Corporation came to fruition in March when Gunma University Heavy Ion Medical Center used carbon ion radiotherapy to treat a patient with prostate cancer. Elekta and Mitsubishi Electric worked to facilitate the use of Elekta’s treatment planning software, XiO®, for delivery with Mitsubishi Electric’s particle beam treatment system.

Compared to proton therapy, carbon ions are heavier and produce a much higher linear energy transfer. Because carbon ions can create a higher energy dose, this type of therapy is designed to be effective in treating select radio-resistant tumors.

Elekta teams in Japan and the United States (St. Louis) worked with Mitsubishi Electric to implement the NIRS (National Institute of Radiological Sciences) new dose calculation engine into Mitsubishi Electric’s particle dose calculation server. This server was then interfaced with XiO by both teams.

“The addition of carbon ions to our treatment planning portfolio is a milestone for Elekta,” says Roberto Pellegrini, Ph.D., director of treatment planning at Elekta. “It demonstrates our commitment to provide clinicians with the flexibility to integrate state-of-the-art planning capabilities across a wide range of radiation therapy delivery techniques.”
