MR-Guided Radiation Therapy with Zeus MRgRT
With the ability to visualize and treat tumors simultaneously, MR-guided radiation therapy has become an essential tool in patient care. The Zeus MRgRT Motion Management QA phantom makes this possible, enabling real-time motion management for better treatment planning.
MR Compatible, Anatomically Realistic, Tissue Equivalent
Thanks to piezoelectric motors and non-ferromagnetic materials, Zeus is fully MR compatible. The motors move a cylindrical insert containing a tracking target through a fillable body, rotating it independently of the superior-inferior direction movement. In addition to visualization, all organs except the lungs offer cavities for ionization chamber dosimetry, allowing completion of the entire QA process, from imaging to planning and verification of delivered dose.
Motion Control Software
Zeus is operated with the user-friendly Motion Control software, which can be installed on any Windows computer.
Motion Control Software Features:
- Built-in and Customizable Waveforms: Five built-in waveforms are available in a standard dropdown menu, and an unlimited number of clinically relevant and patient-specific waveforms can be imported.
- Unlimited Motion Cycles: Choose the number of cycles to be repeated by entering the desired value or opting for continuous repetition.
- Advanced Motion Parameters: The software automatically calculates the best scenario to simulate the real 3D waveform, achieving the simulated volume.
- Beam Latency Calculation: The Zeus motion control box communicates with the Motion Control software to calculate beam latency specific to MR-Linac hybrid systems, which can be performed through superior-inferior motion control of the moving insert/target.
