Abstract: Methods and systems are herein provided for determining operating conditions of a magnetic resonance (MR) scanner based on data of one or more implants of a patient and storing the data of the one or more implants are provided. In one examples, a method comprises obtaining data of one or more implants of a patient from one or more sources; determining one or more configurations of each of the one or more implants; displaying, via a graphical user interface (GUI), the data and the one or more configurations; determining a recommendation configuration based on the one or more configurations; determining a selected configuration via user input to the GUI; and determining operating conditions of an MRI scanner based on the selected configuration for an MRI exam.

Abstract: A method for imaging a subject using a magnetic resonance imaging (MRI) system includes determining a tailored radio frequency (RF) pulse sequence having a plurality of refocusing pulses. In the method, a target peak RF pulse value is determined and a transfer function to convert a first refocusing pulse of the plurality of refocusing pulses to a modified refocusing pulse with the target peak RF pulse value is also determined. A modified RF pulse sequence is generated based on the transfer function and the plurality of refocusing pulses. Finally, magnetic resonance (MR) signals from the subject are acquired based on the modified RF pulse sequence and the medical image of the subject is generated based on the acquired MR signals.
