INTRODUCING RADIANCE 330 PROTON THERAPY Solution
The Radiance 330 Proton Therapy System Series offers a comprehensive range of proton
therapy solutions, enabling healthcare providers to develop single or multi-room capabilities within or adjacent to
existing radiation oncology departments, seamlessly integrating proton therapy as an extension of radiation
oncology.
Featuring a modular design, the Radiance 330 utilizes advanced pencil beam scanning
technology and a compact synchrotron particle accelerator, delivering a clinical treatment energy range of 70 MeV to
250 MeV with upgradeable capacity up to 330 MeV for future proton imaging deployment. As one of the fastest-evolving
fields in healthcare, radiation therapy demands continuous technological advancements, and ProTom is uniquely
equipped to meet these challenges, ensuring faster time-to-market and quicker access for patients in
need.
SYNCHROTRON TECHNOLOGY
The Radiance 330® has the smallest synchrotron footprint in the market. Synchrotrons have
low secondary neutrons and scatter radiation, which lowers the risk of unnecessary and unwanted radiation to the
patient and facility.
The Radiance 330® synchrotron design allows for dynamic modulation of proton beam energy
and intensity in three dimensions utilizing Radiance 330®’s Fidelity Beam™ Scanning System. This allows precise
positioning of the beam and deposition of dose through the use of computer-controlled scanning magnets. This ability
to adjust intensity and energy in real-time, when combined with the system’s active scanning delivery capabilities,
enables the system to deliver three-dimensional, intensity-modulated proton therapy (IMPT). This enhanced level of
dosimetric precision (and reduction in dose to normal tissue) allows clinicians to deliver higher doses to target
volumes, increasing the probability for tumor control; this also enables clinicians to target smaller and/or
difficult-to-reach tumors near sensitive organs.
Because synchrotron technology produces the energy required, no degrading of the beam is
required to alter energy. Therefore, the synchrotron is the more energy efficient choice of the two particle
accelerators. Add to that the cost savings of decreased shielding and an easier installation, and the synchrotron
becomes the top choice for proton therapy facilities.
PENCIL BEAM SCANNING
The Radiance 330® delivers the most advanced form of proton therapy treatment with the
precision of pencil beam scanning.
Pencil beam scanning delivers superior dose sculpting and higher beam efficiencies than
other methods of proton beam delivery. This reduces unwanted side effects, improves long-term
outcomes for patients, and improves the patient’s quality of life.
FIDELITY BEAM SCANNING
The Radiance 330® is equipped with ProTom’s Fidelity Beam™ Scanning System, which uses
matrix spot scanning. This type of scanning accurately “paints” a tumor with the prescribed dose using beam energy
variations to control penetration depth and magnetic steering to guide lateral dose deposition.
ENERGY EFFICIENT TECHNOLOGY
A third-party analysis found the Radiance 330® consumes half as much electricity as
competitors’ cyclotron systems. The Radiance 330® runs more efficiently and generates less heat and electricity as
other proton beam therapy systems - translating to enormous savings on long-term operational costs.
Less shielding and less power are needed, more clean beam delivered.

CLEAN BEAM
The Radiance 330® produces far fewer neutrons than cyclotron-based treatment.
The physical characteristics of a synchrotron ensure that protons lost during production
are only low energy protons, either during injection or after the beam has been decelerated. The lower energy
protons are less able to produce induced secondary radiation activity. This means patients, staff, ancillary
equipment and the building are exposed to fewer neutrons, less shielding is required, and no equipment cool-off
period is needed before entering the vault for routine maintenance.
SUPERIOR, INTEGRATED IMAGING.
It’s designed to interface with in-room imaging solutions, such as computed tomography or
cone beam computed tomography. It’s also equipped with orthogonal imaging, including image-registration software,
which generates a six degree of freedom patient-alignment correction vector.
In addition to supporting ProTom’s own 2D X-Ray solution, the Radiance 330® has the
ability to adapt to a number of off-the-shelf imaging products.
DELIVERY, CONSTRUCTION, AND INSTALLATION TRANSFORMED.
The lightweight, compact, modular design of the Radiance 330® eliminates the need for
heavy equipment in the delivery, construction, and installation phases. This, along with the ability to install the
Radiance 330® above-grade or within existing space, significantly reduces costs.
Developing proton therapy capability with the Radiance 330® represents an economically
viable project, dramatically simplifying construction and installation. The patented and proven design of the
compact synchrotron allows for accelerator interior vault space of approximately 20’ x 30’ and requires 30 - 50%
less radiation shielding than most other systems on the market today. The
lighter-weight, compact technology makes installation easier and simpler, even in the most
space-constrained environment. The largest equipment component requires no hatch, special crane, transport, or
reinforced roadways and is easily moved-in through typical freight or staff entrances. A simpler project with lower
construction and equipment costs is easier to implement, translating to faster time-to-market and faster time to
patients-in-need.
The Radiance 330® runs more efficiently, generates less heat, and consumes far less
electricity than most other proton therapy systems, translating to enormous savings on lifetime operational costs.
Furthermore, the system’s smaller scale makes it possible to add proton therapy as an
extension to an existing cancer treatment program/center, saving on the cost of land and
avoiding the expense of duplicating facilities, ancillary equipment, and personnel.

INTUITIVE DESIGN
The design of the Radiance 330® features an intuitive and user-friendly interface.
Experienced users of a variety of proton beam therapy systems were consulted in the design of the control system.
That empirical information was used to integrate workflow guidance into the operator controls, enabling radiation
therapists to spend less time interacting with the equipment and more time focusing on the patient.
The ProTom-designed screens have uncluttered, organized display panels, with integrated
touch screen technology employed inside and outside the treatment room. Outside the treatment room, the Treatment
Control System screen provides the radiation therapist with a single-screen view of all required patient information
including plan information, treatment fields, room coordinates, digitally reconstructed radiographs, beam status,
and a “beam-on” dose monitor.
Inside the treatment room the control touch-screen provides a unique workflow-driven view.
This user interface functions not only as a control and status display for the equipment, but also as a workflow
guide for the radiation therapist. As the different function “buttons” on the touch-screen are selected, the
therapist is guided through the workflow of treating a patient, including imaging and robotic-patient positioning
with six degrees of freedom. Customizable, pre-programmed movements for both imaging and treatment workflows are
available. Additionally, multiple programmed destination sequences can be saved for clinical use, for physics
quality assurance checks, and for preventive maintenance routines.
