 Abstract: We investigated how the distribution of magnitude and phase of incident electric field affects RFinduced heating near a hip implant. The results showed that varying the incident electric field, for example due to different phantom shape or different landmark position, for two-or three-dimensional implants can result in up to 50% variation of estimated RF-induced temperature rise. To avoid systematic errors in predicting the RF-induced heating, varied distributions of the incident electric field should be applied.
