Conventional proton therapy systems are very large and require a large space for installation. As a result, the installation of proton therapy in urban areas where land is scarce has been slow, and proton therapy has reached only a small percentage of patients. To overcome this situation, B dot Medical is working to commercialize an ultra-compact proton therapy system. This system is overwhelmingly more compact than conventional ones and can be installed in hospitals where it has been difficult to do it due to the size and cost of the system in the past.


Dr. Shojiro Kato, Director of Edogawa Hospital, commented: "We are very pleased that once our hospital is able to offer proton therapy, we will be able to treat patients who have not previously been able to receive proton therapy in Tokyo. We will continue to provide medical care in pursuit of the best possible outcome for all patients."


Takuji Furukawa, Chief Executive Officer of B dot Medical, added: "Three and a half years have passed since we started developing an ultra-compact proton therapy system to bring more advanced cancer treatment to as many patients as possible, and we are finally one step closer to realizing our dream. We hope that the installation of this system will expand the treatment options for many cancer patients. We will do our utmost to obtain approval for the system, install it, start treatment, and provide support afterward."


B dot Medical will continue its efforts to obtain PMDA (Pharmaceuticals and Medical Devices Agency) approval in Japan, aiming for a society in which cancer patients around the world can choose proton therapy.
