Bow condition or the annular central gap which abbreviation cylindrical set of the coil coil (10,30,80), as the primary coil coil (12,32,82) with, the sealed coil coil (14,34,84) with, it possesses the length of axial direction of 10 centimeters at least in the diameter position which is larger than the primary coil coil, extend to the angular section of 180 degrees at least, do not have the coil coil (16,36,86) with it includes. The connected conductor which is arranged in each edge of the central gap (24,44,94), the primary coil coil and the secondary coil coil which are selected are connected electrically. With setting of the scanner, the main magnet (62,64), is arranged outside abbreviation cylindrical set of the coil coil. With setting of the hybrid type scanner, positron tomography of the annular ring (PET) the detector (66), is arranged inside the annular central gap of abbreviation cylindrical set of the coil coil.コイル巻線の略円筒形セット(10,30,80)は、一次コイル巻線(12,32,82)と、一次コイル巻線よりも大きい径位置にシールドコイル巻線(14,34,84)と、少なくとも10センチの軸方向の長さを有すると共に少なくとも180度の角度区間に亘る、コイル巻線の無い弓状若しくは環状の中央ギャップ(16,36,86)とを含む。中央ギャップの各縁部に配置された接続導体(24,44,94)は、選択された一次コイル巻線と二次コイル巻線を電気的に接続する。スキャナの設定では、主磁石(62,64)が、コイル巻線の略円筒形セットの外側に配置される。ハイブリッド型スキャナの設定では、環状リングのポジトロン断層撮影(PET)検出器(66)が、コイル巻線の略円筒形セットの環状の中央ギャップ内に配置される。
