MRI exposure of the Virtual Population: MRIxViP

The development of high resolution anatomical phantoms has enabled the comprehensive analysis of populations, in approaches such as in silico clinical trials. However, such analyses are computationally expensive, particularly for cases where the results must be verified and validated.

IT'IS has precomputed two standard libraries of RF-induced electromagnetic fields (EMF) distributions inside the human body, resulting from exposure to a representative set of radiofrequency (RF) birdcage coils used for 1.5T (MRIxViP1.5T) and 3T (MRIxViP3.0T) closed-bore commercial MRI scanners. Each library consists of induced-field data from all relevant landmark positions simulated our popular Virtual Population (ViP) phantoms in the supine posture in 20 birdcage coils – for a total of more than 12,000 clinical scanning scenarios.

Together with the IMAnalytics module by ZMT Zurich MedTech AG, MRIxViP enables users to perform ISO 10974 Tier 2 and 3 evaluations of implants with full data traceability. The complete toolchain, IMAnalytics with MRIxViP, is qualified by the US FDA for assessment of implant RF compatibility with MR examinations per ISO 10974 or ASTM F2182 as a Medical Device Development Tool (MDDT).
