The world’s first Heavy ion beam rotating gantry using superconducting technologies
Potentials and challenges of Heavy ion remedy
“Cancer” is the highest reason for demise for worldwide. While most cancers remedy strategies proceed to advance daily, “Heavy ion therapy” has been gathering consideration. This is a remedy methodology to irradiate accelerated carbon ions on tumors.
Compared to remedy using X-ray and gamma ray, Heavy ion remedy has a better dose focus stage with a decrease variety of irradiations. Due to this, it might probably shorten the remedy interval and cut back the burden on sufferers.
On the opposite hand, one problem within the standard kind of Heavy ion remedy was the restrict on irradiation angles as a result of tools design. When the irradiation must be minimized on regular organs, it’s essential to tilt sufferers in varied positions, which causes nice bodily and psychological burden on them.
The “Rotating gantry” allows to irradiate from any angle, however the standard rotating gantry for Heavy ion remedy tools was huge. So introduction to normal medical amenities was tough.
The world’s first rotating gantry using superconducting magnets
We aimed to attain protected remedy and downsize the tools to scale back the burden on sufferers. NIRS/QST and Toshiba collectively developed a rotating gantry using superconducting magnets for the first time on this planet. This Heavy ion rotating gantry that may irradiate tumors from varied angles has been considerably contracted and weight (11m in diameter and 13m in size) in comparison with the traditional kind (25m in size) by using Toshiba’s superconducting magnets. The downsizing has enabled the tools to be transported by using a normal transportation methodology. The first one was efficiently put in within the New Treatment Research Facility of NIRS in 2017.

Providing the newest technologies to everybody concerned in remedy
Heavy ion remedy using the Toshiba rotating gantry commenced in May of 2017. The first remedy for a affected person with the top and neck most cancers, was carried out by 16 fractions (4 weeks) and accomplished in June 2017. By finely adjusting the angle, this methodology can focus Heavy ion beam on the tumor whereas avoiding irradiation on regular organs. We have efficiently achieved remedy inflicting much less burden on the sufferers with excessive precision and pure positions for sufferers.
With the considerably downsized rotating gantry using superconducting magnets on this improvement, we will new introduce Heavy ion remedy tools broadly to normal medical amenities. We have additionally improved the remedy effectivity by combining the rotating gantry and respiratory-gated 3D scanning irradiation. These new technologies will contribute to enhancing the irradiation precision, minimizing of remedy time and decreasing of bodily and social burden on sufferers.
This progressive “development of superconducting rotating gantry irradiation equipment for Heavy ion therapy” has been extremely evaluated, and Toshiba and NIRS had been awarded the Prize for Science and Technology (Development Category), the Commendation for Science and Technology by the Minister of Education, Culture, Sports, Science and Technology for 2017.
