MRI test phantom QUASAR™³ᴰ

general purpose

QUASAR™ MRID3D is a lighter, larger and more efficient way to quantify MRI geometric distortion in 3D. This industry-leading distortion analysis system provides sub-millimeter accuracy and is trusted globally by medical physicists for third party MR-SIM and MR-LINAC commissioning and quality assurance. The large FOV (37 cm x 32 cm) hollow boundary phantom design allows for efficient workflow with setup, scan, and analysis in under 10 minutes. MRID3D includes image analysis software with a built-in 3D DICOM Viewer and Region of Interest (ROI) selector, permitting user analysis of smaller custom volumes. Features Workflow Efficiency The MRID³ᴰ design enables quick setup, scanning and analysis of geometric distortion in as little as 10 minutes. The phantom is pre-filled with high T1W mineral oil and is self-contained with a controlled internal environment, which does not require maintenance over time. In addition, auto-detection and auto-registration processes support quick and accurate data analysis. Geometric Accuracy and Stability The MRID³ᴰ system is designed to maintain geometric integrity, resulting in accurate and reliable distortion analysis over the lifetime of the phantom. The combination of precisely machined fiducials, susceptibility-matched materials and structure volume stabilization features result in a superior geometric distortion solution. Spherical Harmonic Analysis Detection Method MRID³ᴰ uses a proven scientific method to quantify MR Geometric Distortion by adaptation of algorithms used in B0 shimming and gradient coil design. This innovative method allows for a highly accurate, hollow and lighter geometric distortion phantom.
