While maintaining the geometric structure of the RF receiving coil and RF transmit coil current burden on the MRI technician or patient does not increase, to provide a technique for improving the quality of images acquired with the MRI apparatus. It is also used in the conductor loop of the RF receiving coil, the magnetic field adjustment conductor loop to be placed in order to enhance or shielding the rotating magnetic field B 1 of the RF transmission coil is created between the RF transmitter coil and the subject. Then, the drive to reduce the non-uniformity of the rotating magnetic field B 1, the conductor loop to act as a magnetic field adjustment conductor loops in the conductor loop, which constitutes the RF receiving coil.現状のRF送信コイルおよびRF受信コイルの幾何学的構造を維持しつつ、患者やMRI技師への負担も増大させず、MRI装置で取得する画像の質を向上させる技術を提供する。被検体とRF送信コイルとの間にRF送信コイルが生成する回転磁界B1を遮蔽もしくは増強するために配置する磁場調整用導体ループを、RF受信コイルの導体ループで兼用する。そして、RF受信コイルを構成する導体ループの中の磁場調整用導体ループとして機能させる導体ループを、回転磁界B1の不均一を低減するよう駆動する。
