The effects of magnetic field distortion on the accuracy of passive device localization frames in MR imaging

Purpose: The interventional magnetic resonance (MR) imaging environment presents many challenges for the accurate localization of interventional devices. In particular, geometric distortion of the static magnetic field may be both appreciable and unpredictable. This paper aims to quantify the sensit...
