TOKYO--(BUSINESS WIRE)--Hitachi, Ltd. (TSE:6501, “Hitachi”) today announced that Mayo Clinic in
Phoenix, AZ began treating patients with its advanced PROBEAT-V proton
therapy system on March 14.
The PROBEAT-V is a state-of-the-art proton beam therapy system used to
deliver Hitachi’s Discrete Spot Scanning capability to each treatment
room. The 190 degree half gantries provide efficient yet spacious
treatment room environments. Hitachi’s smallest treatment spot size to
date enables the system to achieve highly precise treatments.
Mayo Clinic in Rochester, Minnesota is also equipped with an identical
proton therapy system and has been treating patients since June, 2015.
Mayo Clinic treats more than 1.3 million patients annually from all 50
states and 143 countries. Mayo Clinic has maintained its position as one
of the top hospitals in U.S. News & World Report rankings for more than
Hitachi has now supplied proton therapy systems for four centers in the
United States, with a fifth system currently under construction.
Given the growing demand for technical and clinical advancements in the
treatment of cancer, interest in proton therapy is on the rise, with
more and more hospitals and cancer treatment facilities venturing into
this area. Hitachi will continue to globally expand the healthcare
business where proton therapy is its flagship solution, and contribute
to cancer treatment around the world.

Overview of Proton Beam Therapy
Proton Beam Therapy (PBT) is an advanced form of external beam
radiotherapy. Protons from hydrogen atoms are extracted and accelerated
up to 70% the speed of light. Its energy is concentrated directly on the
tumor while avoiding radiation dose to the surrounding healthy tissues.
PBT improves the quality of life for cancer patients since the patient
experiences no pain during treatment and the procedure has very few side
effects compared with that of traditional radiotherapy. In most cases,
patients can continue with their normal daily activities while
undergoing treatment. Because there are fewer side effects, PBT is
expected to expand, especially for pediatric treatment.
Overview of Spot-Scanning Irradiation Technology
Spot-scanning irradiation technology does not scatter proton beams as
with conventional proton beam therapy. Rather, it repeatedly turns a
narrow proton beam on and off at high speed as it progressively changes
location to irradiate entire tumor volumes. Protons can be aimed with
high precision according to the targeted tumors, even those with complex
shapes, while minimizing the impact on nearby healthy tissue.
