Gated MRI Simulation and Guidance QA for imaging, planning, and delivery KEY FEATURES • • • • MR safe respiratory motion QA system Compatible with low and high field strength MRI scanners Ability to stream patient-specific waveforms without any additional programming Waveforms: programmable and library, user selected, editable, respiratory range of 1 second per breathe to 15 seconds per breath Compact mechanical design enables system to operate within the magnet bore Diamagnetic phantom consists of MR safe materials that produce negligible susceptibility artefacts/image distortion MRI compatible motor is unaffected by the magnetic field at 1.5T and 3T System is properly RF shielded and does not degrade MR image SNR in OEM system noise testing Interchangeable inserts for multiple testing applications Linear motion phantom with twisting SPECIFICATIONS (Preliminary) • • • • • • • • • • Maximum linear motion: +- 20mm for oscillation mode, +-15mm for programmable mode Maximum twisting rotation: +- 30 degrees for oscillation mode, +- 22 degrees for programmable mode Oval: 20 cm deep, with user selectable insert location of central or offset for Imaging or RT preferences Motion insert: 25 cm long, 2 kg max Motion accuracy: within 0.25mm Includes surrogate for bellows Motion platform accessory Adaptor accessory for regular QUASAR™ Respiratory Motion Phantoms Surroga

SIMULATE PATIENT BREATHING The QUASAR™ MRI-Compatible Respiratory Motion Phantom is designed to move a cylindrical insert in the superior/inferior direction within a body shaped oval. Interchangeable inserts are available for multiple testing applications, including imaging, planning, and delivery. The QUASAR™ MRI-Compatible Respiratory Motion Phantom uses the same software application as the QUASAR™ Respiratory Motion Phantom to display, edit, and run patient-specific respiratory waveforms. Waveforms are created using the application or imported from vendor specific MR respiratory tracking systems...
