In General

Traditionally the length of three football fields, today’s systems are more compact and in turn, more affordable than ever.

Proton therapy is an advanced form of radiation treatment that targets tumors with precision. Yet, only a handful of facilities worldwide currently offer it. Citing space and affordability issues, many facilities believe proton therapy to be out of reach. The good news is that proton therapy systems are getting smaller.


One factor driving the increasing affordability of proton therapy treatment is the emergence of smaller particle accelerators. While these accelerators, central to the delivery of treatment, account for a majority of facility space requirements, other treatment-related items and construction considerations also play a role in the amount of space needed to deliver treatment. In addition to the size of its particle accelerator, the following factors might also impact a facility’s choice of a proton therapy treatment system.

Interruptions of daily operations

A proton therapy system installation in an existing radiation therapy facility, that does not disrupt daily operations, is significant. Allowing patients to continue necessary treatment, without interruption, means little to no impact on patient comfort and experience at a facility, or revenue generation.


Multiple tractor-trailer trucks, heavy equipment, and a facility hatch have been standard requirements for delivery and installation of traditional proton therapy systems. Reducing these requirements, and thereby costs make delivery and installation easier.


Reducing the size of the particle accelerator and proton therapy system also reduces the cost of facility space and construction. Using lighter-weight or standard construction equipment reduces overall installation costs and allows for less underground construction reinforcement, further reducing the cost of materials.


Looking for both treatment efficacy and affordability? Consider the Radiance 330® Proton Therapy System. Lightweight and compact, it requires an installation area smaller than that of a basketball court. This space is able to accommodate not just the particle accelerator, but also the treatment room, control room, and all necessary concrete shielding. Its small footprint makes it possible for it to be delivered and installed where other systems cannot, including above-grade or within an existing space.
