PROBLEM TO BE SOLVED: To provide an MRI apparatus capable of performing time-varying imaging at the same imaging position as the past imaging position and more correctly and more conveniently performing time-varying diagnosis and diagnosis of postoperative observation.SOLUTION: A map image of the imaging position of a subject is created using a pressure sensor and is compared with a map image in a storage unit to reproduce a past imaging position desired in time-varying imaging.COPYRIGHT: (C)2015,JPO&INPIT【課題】過去の撮像位置と同じ撮像位置で経時撮像ができ、経時的な検診や術後観測の診断をより正確、簡便に行うMRI装置を提供する。【解決手段】圧力センサーで被検体撮像位置をマップ画像にし、記憶マップ画像と比較して、経時撮像において所望した過去の撮像位置を再現する。【選択図】図2
