      Hitachi Particle Beam Therapy System (PBT)

      Particle therapy is one of the most advanced forms of cancer treatment. The delivery of high dose to a target with high precision and reduced side effects are the primary qualities that make this therapy so unique. Refining the technology and expanding its accessibility to more cancer patients did not happen overnight. Years of research and development, a broad range of technical and clinical experience, and collaborative work with world-class hospitals and cancer centers have given Hitachi a reputation for providing the medical community with the highest level of quality, exceptionally high clinically availability and cutting-edge innovations in particle therapy.

      What is Particle Therapy

      It can maximize radiation dose to tumor sites while sparing adjacent healthy tissues, and is especially effective in treating many rare cancers, especially pediatric cancers. Particle beams enter the body releasing small amounts of energy until reaching tumor site, where the particle stops and deposits the vast majority of its energy over a very short distance. As the result, short-term side effects in uninvolved tissues and organs are reduced or avoided, unlike external beam radiation treatment using X-rays.

      Ultra High Precision Beam Control Technology

      Hitachi’s technical advantages are based on its incomparably precise beam control technology – resulting from continual refinement of electromagnet and synchrotron accelerator design since 1970’s. Leveraging its core strength, Hitachi has collaborated with customers to develop market- leading innovative technology, optimized to meet operational and clinical needs.

      Intensity Modulated Particle Therapy

      Hitachi was first to introduce FDA 510(k) cleared and clinically implemented scanning technology to the US market. Scanning beam technology is today’s new standard in precision beam delivery. Hitachi’s spot scanning system is used to deliver Intensity Modulated Particle Therapy (IMPT) – an advanced form of particle beam treatment. Hitachi particle therapy systems have treated more than 60,000 patient to date, many with Hitachi’s industry leading, clinically proven IMPT.

      Real-time image Gating for Motion Management

      Irradiation of targets that move due to respiratory or other factors has posed a challenge especially with high-precision scanning beams. Hitachi and Hokkaido University collaborated to develop Real-time image Gated Particle Therapy (RTGT) – an innovation that enables high dose beam delivery to moving tumors while sparing surrounding healthy tissues and organs.

      Gantry-mounted CBCT

      Precise patient alignment and assessment of anatomy changes require high-resolution imaging of the tumor region at the time of treatment. Gantry-mounted Cone Beam CT, co-developed with Hokkaido University, provides 3D images of patients in the treatment position. Alignment software and robotics enables automatic patient positioning – dramatically increasing the precision of irradiation when used with Hitachi’s beam control technology. CBCT is a key element in the implementation of adaptive therapy.
