摘要： A radio-frequency (RF) coil apparatus for magnetic resonance (MR) systems (100, 200, 300, 400, 500, 600, 700, 900, 1000) includes a base (102, 502, 702, 902, 1002) having opposed sides (121), a surface (124) to support an object of interest (OOI) for scanning, and fasteners (127) situated at the opposed sides, A positioner (104, 304A, 304B, 504, 604, 704, 1004) is configured to be releasably attached to the base and has a body (130) extending between opposed ends and fasteners (134,) situated at the opposed ends of the body, The body is configured to form an arch between the opposed ends. An upper section (106, 606, 706, 906, 1006) has at least one RF coil array (142) for acquiring induced MR signals, and is configured to be positioned over the positioner.

摘要： An arrangement and system places an external cable into a slot. The arrangement includes a slot extending from a first end to a second end. The slot includes a recess configured to receive a cable therein. The arrangement includes a movable component configured to slide along a length of the slot. The movable component includes a first end and a second end. Sliding the movable component along the slot in a first direction from the first end to the second end of the slot one of frees a first portion of the cable from the slot or places a second portion of the cable in the slot.

摘要： A balun is provided that is suitable for use with miniature coaxial cables and that obviates the need to cut the cable in order to install the balun. A portion of each coaxial cable that extends from the RF receive coils to the RF receiver is wound multiple times around a device to form an inductor. The inductor may be used with or without a separate resonant circuit. If used with a separate resonant circuit, the inductor and the resonant circuit couple with one another to generate a coupled impedance that provides common-mode noise suppression at the frequency of interest. If used without a separate resonant circuit, the inductor formed in the cable provides an inductance and the capacitance between the windings coupled with the inductance provides a series impedance that suppresses common-mode noise at the frequency of interest.
