Modelling regulatory compliance of occupationally exposed MRI workers during gradient pulsing
Synopsis: Magnetic resonance technology employs a wide range of electromagnetic fields for rapid generation of high-resolution anatomical images. These electromagnetic fields are known to interact with living tissue in different ways and mechanisms causing potentially detrimental physiological effects. This study presents numerical investigations into the magnitudes and spatial distributions of induced in situ electric fields and associated current densities in tissue-equivalent, whole-body, male and female models of occupational workers when standing close to the ends of three cylindrical gradient coils. The results have been compared to the most recent IEEE, ICNIRP and EU-Directive 2004/40/EC standards for magnetic and electric field exposure in controlled environments.
