Phemto® Ultra-compact Proton Therapy System
Approval of the health authority in the respective country is required before clinical use.
■Innovative Gantry Structure Enabling Miniaturization: Magnetic Gantry™
Phemto® represents B dot Medical’s groundbreaking achievement in developing an ultra-compact proton therapy system. Striving to achieve a size comparable to X-ray (LINAC) therapy systems, Phemto® adopts the Magnetic Gantry™, a proprietary development by B dot Medical that utilizes superconducting electromagnets to precisely bend the proton beam.
Takuji Furukawa, President and CEO of B dot Medical, commented on this milestone: “We are delighted to receive regulatory approval for our proprietary Magnetic Gantry™ technology under the pharmaceutical law. It has been four years since we embarked on the development journey in 2019. Obtaining approval for manufacturing and sales as a medical device is a significant milestone for a deep tech startup like us. We remain committed to advancing technology and contributing to the widespread adoption of proton therapy. Our journey of technological development continues to promote the accessibility of proton therapy.”

■About Proton Therapy
In proton therapy, a precisely directed proton beam targets the tumor with minimal impact on surrounding healthy tissues. Proton therapy promises to enhance patients’ quality of life by enabling cancer treatment without disrupting their daily routines.
However, proton therapy is currently accessible to only a limited number of patients and remains less common than conventional x-ray therapy. The high construction costs and space requirements within hospital campuses have posed significant challenges to its widespread adoption. As of October 2023, there are just 113 operational proton therapy facilities worldwide, a stark contrast to the prevalence of conventional radiation therapy.
B dot Medical has developed the remarkably compact proton beam cancer treatment system “Phemto®” with the aim of advancing the accessibility of proton therapy. Leveraging our proprietary technology, we have minimized the system to a size comparable to X-ray (LINAC) therapy systems, facilitating its introduction into urban areas where proton therapy implementation was historically challenging. This breakthrough also encourages adoption in hospitals that, due to cost considerations, had previously abandoned the idea of incorporating proton therapy. As a result, we anticipate a substantial increase in the number of facilities, contributing to the widespread availability of proton therapy.
