1. A computer-implemented method for controlling a ramping process of a superconducting magnet of a magnetic resonance imaging device, comprising:
receiving, via an interface, cryocooler status data indicative of a status of a cryocooler configured to cool the superconducting magnet;
receiving, via the interface, superconducting magnet data indicative of a parameter of the superconducting magnet comprising a value of an electrical property and/or a physical property of the superconducting magnet that is measured via at least one sensor;
determining, via processing circuitry, an operational status of the magnetic resonance imaging device based upon (i) the cryocooler status data, and (ii) the superconducting magnet data; and
generating, via a controller, a control signal that controls the ramping process of the superconducting magnet,
wherein the control signal is from among a set of dedicated control signals, each respective one of the dedicated control signals being generated based upon the determined operational status of the magnetic resonance imaging device and the cryocooler status data to control the ramping process of the superconducting magnet in response to (i) the cryocooler status data indicating that a turn-off time of a compressor of the cryocooler exceeds a predetermined threshold time period, and (ii) the superconducting magnet data.
