A Novel Device Model Validation Strategy for 1.5- and 3-T MRI Heating Safety Assessment |
Abstract | ||
|---|---|---|
This article presents a novel test instrument and strategy for active implantable medical device (AIMD) model validation under a radiofrequency (RF) field generated by a magnetic resonance imaging (MRI) system. A high electric field generator is developed as an alternative instrument for standard MRI RF coils. This system is both compact and power efficient. In addition, a set of validation pathways are proposed based on the Hadamard matrix. These pathways provide low correlations among incident electric fields and yet generate relatively high temperature rises. Two generic AIMDs with different lengths are used to validate the strategy experimentally. It is demonstrated that this method provides an efficient and effective alternative for future AIMD model validation under MRI RF emissions. |
