The invention provides for a multi-element transmit coil (100) for a magnetic resonance imaging system (300). The multi-element transmit coil comprises multiple surface coil elements (102) with a coil circuit (104) that has an integrated a radio-frequency sensor (106, 604, 704, 804). The multi-element transmit coil further comprises a power monitoring unit (108) with an analog-to-digital converter (808). The power monitoring unit comprises a processor connected to each analog to digital converter that is operable for receiving a radio-frequency measurement for generating specific absorption rate data (348) for each of the multiple surface coil elements. The multi-element transmit coil further comprises an optical data transmission system (110) connected to the processor. The optical data transmission system is operable for connecting to a magnetic resonance imaging system controller (312, 330). The optical data transmission system is operable for transferring the specific absorption rate data to the magnetic resonance imaging system controller.
