Abstract

See full text

The invention relates to a magnetic resonance imaging (MRI) system with emergency quench. According to the invention, a magnetic resonance imaging system (1) comprising a superconductive magnet (2) with windings (3) for generating a magnetic field, an emergency button (4) and a circuitry logic (5) for controlling the magnet (2) coupled to the magnet (2) and to the emergency button (4), wherein the magnet (2) is operable in a superconducting state and in a normal conductivity state, respectively, and the emergency button (4) and the circuitry logic (5) are configured in such a way that, when the magnet (2) is operated in the superconducting state, actuating the emergency button (4) by a user in a predefined first way initiates ramping down the magnetic field while dissipating energy stored in the windings (3) of the magnet (2) to an external dissipation device (6), and actuating the emergency button (4) by a user in a predefined second way which is different from the first way initiates quenching the magnetic field by heating up at least part of the windings (3) of the magnet (2) leading to a dissipation of energy stored in the windings (3) of the magnet (2) as additional heat to the magnet (2). In this way, an easy and reliable way to control a superconductive magnet (2) of an MRI system (1) is provided in an event in which the magnetic field has to be removed.
