March, 2021 – ProTom is pleased to announce that its single-room Radiance 330® Proton Therapy System at the Gordon-Browne Proton Therapy Center at Massachusetts General Hospital (MGH) has been treating patients for over one year. ProTom continues to support the MGH team to deliver the most advanced proton therapy treatment to patients.

The Radiance 330 Proton Therapy System at MGH is a compact, single-room system equipped with advanced pencil beam scanning and integrated imaging. The Radiance 330 compact synchrotron can be installed within an interior accelerator vault space of 20′ x 30′ and requires up to 40% less radiation shielding. The lighter-weight, compact technology simplifies the installation process; and the largest component of any proton system configuration—the accelerator—requires no special road transport, facility hatch, or extraordinary cranes and can be delivered through typical freight or staff entrances.  The MGH Radiance 330 system was installed in an existing, fully operational radiation oncology department, 3 levels below ground.
