摘要： The present invention provides a phantom (200) for use in a magnetic resonance (MR) imaging system (110) with a set of resonating volumes (206) positioned in a base body (202), whereby the base body (202) has a spherical or ellipsoid shape in accordance with a volume of interest (203) of the MR imaging system (110), and the resonating volumes (206) are located at a circumference of the base body (202). The phantom is used in a method for evaluating the magnetic field of a main magnet (114) of a magnetic resonance (MR) imaging system (110), comprising the steps of positioning the phantom (200) within the main magnet (114), performing a 3D spectroscopic MR measurement of the phantom (200) using the MR imaging system (110), thereby measuring resonances of the resonating volumes (206), assigning the measured resonances to the resonating volumes (206), and evaluating the magnetic field of the main magnet (114) from the MR measurement of the phantom (200) based on the measured resonances of the resonating volumes (206). Accordingly, the MR imaging system itself is directly used for determining the magnetic field of its main magnet. Accordingly, the MR imaging system itself can be used as measurement equipment, instead of a separate NMR magnetometer, which is required for conventional determination of the magnetic field.

摘要： An apparatus including an electrically conductive coil which produces a magnetic field when an electrical current passes therethrough; a selectively activated persistent current switch connected across the electrically conductive coil; a cryostat having the electrically conductive coil and the persistent current switch disposed therein; an energy dump; at least one sensor which detects an operating parameter of the apparatus and outputs at least one sensor signal in response thereto; and a magnet controller. The magnet controller receives the sensor signal(s) and in response thereto detects whether an operating fault (e.g. a power loss to the compressor of a cryocooler) exists in the apparatus, and when an operating fault is detected, connects the energy dump unit across the electrically conductive coil to transfer energy from the electrically conductive coil to the energy dump unit. The energy dump unit disperses the energy outside of the cryostat.
