C-RAD announced today that it is entering into a collaboration with the Zuid-Oost Nederland Protonen Therapie Centrum (ZON-PTC) located at and largely owned by MAASTRO clinic, to develop integration of its Catalyst PT system to the Mevion S250i Proton Therapy System. As part of the collaboration MAASTRO has ordered the Sentinel 4DCT and Catalyst PT system.
C-RAD offers a specific version of its Catalyst System for use in proton and particle therapy – Catalyst PT. It is based on the patented Catalyst technology and software as well as the hardware are tailored for the application in this environment.
In a first step the Catalyst system will be installed on a Varian TrueBeam linear accelerator at MAASTRO clinic to train future proton therapy staff in the clinical application of surface tracking. It is expected that first patients are treated on the proton therapy vault by the end of this year.

The proton therapy treatment room is currently under construction. The customer decided for a compact accelerator developed by the US based company Mevion Medical Systemsâ. As part of the collaboration the team in Maastricht together with Mevion and C-RAD have agreed to implement a workflow that features a seamless workflow with continuous motion monitoring from initial patient setup, throughout x-ray imaging until the completion of each fraction. With the help of C-RAD Catalyst PT MAASTRO clinic and ZON-PTC will also be able to offer respiratory gated treatments to their patients.
“In Maastricht we want to become a world leader in proton therapy with a special focus on moving targets (lung cancer and breast cancer). Therefore, the Catalyst PT in combination with the Sentinel system on the CT scanner plays a crucial role in establishing this goal, says Geert Bosmans, PhD, Head of Proton Physics at ZON-PTC. With C-RAD we found a partner to implement and improve solutions for high-precision proton treatments.”
C-RAD products are distributed by the Dutch company AEP International B.V. AEP is responsible for sales and service for the C-RAD Sentinel and Catalyst product line as well as for the Cyrpa laser in the Benelux market. The company has more than 35 years of experience in sales and marketing of high-quality linear accelerator components, as well as representing many renowned RT brands in the Benelux area.
“We are very proud to be part of this collaboration between ZON-PTC, C-RAD, Mevion and AEP” says Guido Moonen, responsible account manager at AEP International B.V; “We are convinced that patients of ZON-PTC will greatly benefit from the advantages of Surface Image Guided Radiation Therapy.”
