Open-Source Simulator of Imaging Near Metal at Arbitrary Magnetic Field Strengths.

ABSTRACT:

Purpose

The increasing prevalence of orthopedic metallic implants necessitates optimization of MRI methods to monitor surrounding tissues and identify complications. The emergence of contemporary mid- and low-field systems as promising platforms for imaging around metal requires development of new protocols optimized for these field strengths. Motivated by these, we develop a simulation framework that predicts MRI performance near metallic implants, considering B0 field strength and multi-spectral imaging (MSI) parameters.

Methods

A simulation framework for imaging near metal incorporating 3D implant and 3D human anatomical models, and imaging and sequence parameters is developed. MSI acquisitions are simulated based on susceptibility-induced field shifts. Validation is perf
