Abstract
A magnetic resonance imaging system () acquires magnetic resonance data () from a subject () that may include an electrically conductive object (e.g. an implant or a medical device). The magnetic resonance imaging system includes a radio-frequency transmitter () for generating a radio-frequency transmit field for acquiring the magnetic resonance data using a radio-frequency antenna (). The radio-frequency transmitter has multiple transmit channels. The radio-frequency antenna comprises multiple antenna elements () each adapted to connect to an antenna element. The amplitude and phase values of the RF transmit field of each of the transmit channels can be selected such that the magnetic field generated by the RF antenna is minimized at the location of the electrically conductive object, thereby reducing RF heating of the object.
