With the increasing interest in MRI-guided interventions, treatment accuracy requires more advanced QA tools to measure distortion and establish accepted thresholds. The QUASAR^TM MRID^3D Geometric Distortion System is an advanced time and workflow-efficient method for measuring a full 3D distortion vector field.

The QUASAR^TM MRID^3D is a lighter, larger, hollow boundary phantom that uses harmonic analysis to achieve sub-millimeter accuracy. Full setup, scan and analysis workflow can be completed in less than 10 minutes.

In addition to automated distortion quantification, the phantom software offers advanced features, including phantom susceptibility distortion correction, patient table roll pitch yaw and offsets, spherical harmonic coefficient output and separate B₀/GNL distortion quantification.

This webinar, presented by Enzo Barberi, will highlight the advanced features of the MRID^3D Geometric Distortion Analysis System, including a demonstration of the data analysis and workflow within the hardware and software platform.

Enzo Barberi is the director of MR QA Technology at Modus QA. Enzo focuses on early stage R&D through to new QA technology acceptance and commercialization, working with all stakeholders including early adopters and collaborators, MR Linac and MR SIM OEMs, NEMA/MITA and IEC Standards bodies, government funding agencies involved in public/private partnerships, as well as with late adapting clinicians.
