Abstract: The invention relates to shim elements (100, . . . , 115) for magnetic resonance applications. According to the invention, the shim elements (100, . . . , 115) comprise shim blocks (101, . . . , 115) which are each separate from each other such that each shim block (101, . . . , 115) may be individually inserted into a shim opening (9) of a magnetic field-generating unit (2) of the magnetic resonance apparatus (1), wherein each shim block (101, . . . , 115) comprises a relative amount of shim iron (10), and the set comprises at least two shim blocks (101, . . . , 115) for which the respective amount of the shim iron (10) is different from each other. In this way, the shimming procedure may be simplified and the shim capacity may be increased to a high pultrusion volume.

Abstract: Disclosed herein is an arrangement (100) for loosening a moveable part (104) resting at a first position within a switchable device (106) of a magnetic resonance imaging system (300). The arrangement (100) comprises the moveable part (104), an inductor (102), and an alternating current supply (108). The moveable part (104) is configured to switch the switchable device (106) at least from a first state to a second state by moving from the first position to a second position within the switchable device (106). The inductor (102) is connected with the alternating current supply (108) via an electrical connection (110). The alternating current supply (108) is configured to supply the inductor (102) with an alternating current via the electrical connection (110). The inductor (102) is further configured to loosen the moveable part (104) by inducing vibrations of the moveable part (104), when the inductor (102) receives the alternating current from the alternating current supply (108) via the electrical connection (110).
