Zusammenfassung:	To provide an MRI system reception coil device 3 for use with a main MRI scanner device.SOLUTION: A device includes: at least one primary reception coil 6 having a first size determined by a first impedance in a predetermined frequency and a cross section defined by the primary reception coil; and at least one auxiliary reception coil 7 having a second size determined by a second impedance in the predetermined frequency and a cross section defined by the auxiliary reception coil. The first impedance is lower than the second impedance, and the first size is larger than the second size.SELECTED DRAWING: Figure 8B 【課題】メインＭＲＩスキャナ装置と共に使用するためのＭＲＩシステム受信コイル装置３を提供する。【解決手段】装置は、所定の周波数での第１のインピーダンス及び一次受信コイルによって画定される断面によって定められる第１のサイズを有する少なくとも１つの一次受信コイル６、並びに前記所定の周波数での第２のインピーダンス及び補助受信コイルによって画定される断面によって定められる第２のサイズを有する少なくとも１つの補助受信コイル７を備え、第１のインピーダンスが第２のインピーダンスより低く、第１のサイズが第２のサイズより大きい。【選択図】図８Ｂ
