Evolution in 4D Treatment

Recent advances in treatment planning and delivery systems have led to consistently achieving optimal results. And now with the revolutionary Catalyst, you can get the same level of confidence when controlling the only remaining variable – the patient.

During treatment, patient breathing, as well as movements of the tumor or normal tissue can impact the clinical result and by missing targets or causing extra dose distribution to normal tissue.

The Catalyst system is a revolutionary solution for Surface Image Guided Radiation Therapy (SIGRT), coupled with application software optimized for work-flow integration.

Catalyst offers a complete solution on 3D CRT, IMRT for online patient tracking before and during treatment delivery, thus ensuring the best possible therapeutic and palliative treatment outcome without non-prescribed doses. c4D software is integrated with major radiation therapy equipment suppliers to streamline workflow, including beam and couch control.

Real time 4D SIGRT Solution

Real time SIGRT solution for the whole 4D treatment workflow, from Setup and Positioning to Intra-Fraction Motion Monitoring to Respiratory Gating Treatment.
Patented color map projected on patient body during setup for immediate posture correction by patient.
Respiratory gating treatment support.
Optional audio-visual coaching helps the patient follow optimal breathing patterns. Patient baseline is calculated as an absolute parameter that can be used during treatment delivery.
Breath-hold, deep inspiration and coached/free breathing modes are all supported.

High level of patient safety and comfort

Audio-visual coaching through in-room speakers and video solution, assisting the patient to follow the optimal breathing pattern.
Dose-free motion management
No markers on or around the patient

Sophisticated software to streamline the workflow

Multi-vendor interfaces have been developed to ensure a seamless clinical workflow, i.e. Varian TrueBeam, C-series; Elekta VersaHD, Infinity, Synergy

Increasing productivity without compromising treatment quality

Potential to improve quality and speed of the positioning process, for example, extremity sarcoma
Highly integrated QA/QC procedure – Daily QC within 5 minutes
Non-rigid algorithm improves accuracy and speed of clinical application without extra time for ROI design.
Potential to reduce the frequency of other IGRT technologies
