PROBLEM TO BE SOLVED: To provide a small diameter receiving coil in which receiving sensitivity is improved by resolving a part where setting is hard due to interference to the small diameter coil with a part (such as nose and ear) of a test object person in MRI imaging.SOLUTION: A receiving coil of an MRI device has a structure allowing the receiving coil to be divided into an upper part and lower part, and has a first mode in which a connection component is arranged in the upper receiving coil and a second mode in which the connection component is removed and a connector cover having an opened section is provided. The receiving coil is provided with a mode switching circuit for switching the first mode and the second mode according to an interference state of the test object person and the upper receiving coil.COPYRIGHT: (C)2014,JPO&INPIT【課題】MR撮像において被検者の対象部位の一部分(例えば、鼻、耳など)が小径の受信コイルに干渉してセッティングが困難な部分を解決して、受信感度を向上させた小径の受信コイルを提供することである。【解決手段】MRI装置の受信コイルにおいて、受信コイルが上側と下側コイルに分断可能な構造を有し、上側受信コイルに設けられた接続部品を具備する第1モードと、該接続部品が取り外され開放部分を有するコネクタカバー部品を具備する第2モードとを有し、被検者と上側受信コイルとの干渉状態に応じて、第1モードと第2モードとを切り換えるモード切り換え回路を備えることを特徴とする。【選択図】図4
