The improtance of ultrahigh fields MRI has been rapidly increased due to its advantages in high resolution and signal-to-ratio. In this study, the SAR was analyzed in accordance with the conditions of insertion DBS and the electromagnetic field is controlled by multi-channel coil. Our reserch demonstrated the field control method using convex optimization from the fields data can be considered as a good strategy to drive the individual parameters of the RF coil for solving the inhomogeneity and SAR limitations, and it is safer for patients.
