Catalyst PT

Particle therapy (PT) is currently based on the use of protons or carbon ions for the treatment of deep-seated or radio-resistant tumors, as well as recurrent cases, which are known to lead to poor prognosis or counter-indications for photon treatments. An increasing interest has recently been observed in the number of cases and types of cancers.

Catalyst PT – C-RAD Advanced solution for Particle Therapy

C-RAD offers a complete end-to-end Surface Image Guided Radiation Therapy (SGRT) solution on PT from 4D CT to patient preparation pre-setup and all the way to online patient tracking during treatment delivery, thus ensuring the best possible treatment outcome without non-prescribed doses. The PT solution from C-RAD can be used for proton therapy and heavy ion therapy.

Catalyst PTTM is a leading SGRT solution that supports the entire
proton therapy workflow from simulation to treatment.
