The importance of ultra-high field Magnetic resonance imaging (MRI) has been increased rapidly due to advantages of high resolution and signal-to-noise ratio. In this study, the specific absorption rate (SAR) was analyzed in accordance with the conditions of insertion deep brain stimulation (DBS) system and the electromagnetic field controlled by multi-channel coil. Our research demonstrated the method of field control using convex optimization (CVX) from the magnetic field data can be considered as a good strategy to drive the individual parameters of the RF coil to alleviate inhomogeneity of magnetic field and meet SAR standard, and it is much safer for DBS patients.
