Description
The CIRS Zeus MRgRT Motion Management QA phantom is designed to address the integration of MR imaging in radiation therapy for facilitating real-time motion management. Zeus is MR Safe due to the use of piezoelectric motors and non-ferromagnetic materials, and is designed as a single unit with a piezo actuator fixed permanently to a base plate on which the MRI body “snaps”. CIRS Motion Control software drives this phantom as well as the other phantoms from the CIRS dynamic family.
Features
• Piezoelectric motors, non-ferromagnetic materials => MR safe
• Allows for positioning within magnet bore due to piezoelectric motors
• Easy setup, removal, alignment, positioning
• Organic shaped Organs at Risk and moving target
• Can be imaged in MRI, CT, PET and hybrid systems
• Ion chamber dosimetry in Liver, Kidney, Spine and moving target
• 3D tissue equivalent Spine for bone landmark
• Two independently programmable motions for the moving target
• Import, edit, and save patient specific breathing waveforms in addition to built-in QA waveforms
• Calculate beam latency from beam-on, beam-off signal
