摘要:
PROBLEM TO BE SOLVED: To enable MRE imaging of an inspected portion in a body as compared with a conventional configuration. SOLUTION: A magnetic field generator (2) for generating a static magnetic field, a gradient magnetic field, and an alternating magnetic field for an inspected part (101) of a subject (4), and an introduction part extending along a lumbar spine (17). (16b) and a concave connection portion (16a) formed by connecting to the introduction portion (16b) and extending along the direction from the outside of the body toward the body surface, and connected to the body surface side of the portion to be inspected. With the part (16a) in contact, the sound pressure from the sound source (19) connected to the introduction part (16b) is applied to the body surface of the subject (4) to vibrate the part to be inspected (101). The MR phase image that acquires the MR phase image according to the phase of the electromagnetic wave signal based on the vibration applying member (16) that applies the vibration and the electromagnetic wave acquired according to the echo time corresponding to the timing when the gradient magnetic field is applied. An imaging device (1) comprising an acquisition means (54c). [Selection diagram] Fig. 2【課題】従来の構成に比べて、体内の被検査部についてMRE撮影可能にすること。【解決手段】静磁場と傾斜磁場と交番磁場とを被検者(4)の被検査部(101)に対して発生させる磁場発生装置(2)と、腰椎(17)に沿って延びる導入部(16b)と、導入部(16b)に接続して形成され且つ体外から体表に向かう方向に沿って延びる凹部状の接続部(16a)と、を有し、被検査部の体表側に接続部(16a)が接触した状態で、導入部(16b)に接続された音源(19)からの音圧を被検者(4)の体表に付与することで被検査部(101)に振動を付与する振動付与部材(16)と、傾斜磁場を印加する時期に対応するエコー時間に応じて取得された電磁波に基づいて、電磁波信号の位相に応じたMR位相画像を取得するMR位相画像の取得手段(54c)と、を備えた撮影装置(1)。【選択図】図2
