Abstract

A magnetic resonance imaging system (100) comprising a main magnet (104) for generating a main magnetic field within an imaging zone (108); a radio frequency, RF, antenna (114), comprising an RF input terminal (300) and an RF output terminal (302); an RF system for supplying radio-frequency power to the RF input terminal (300) to energize the antenna (114), the antenna (114) being further adapted for picking up magnetic resonance signals (144) from the imaging zone (108); a data acquisition system (126) for receiving the magnetic resonance signals (144) from the RF output terminal (302); wherein the RF input terminal (300) is in galvanic connection to the antenna (114) and the RF output terminal (302) is inductively coupled to the antenna (114).
