The thermostat closure assembly is configured to close an opening of a magnetic resonance imaging apparatus (MRD) having an open hole extending along a longitudinal axis of the MRD having a distal end and a proximal end, the hole being in the near Terminated by an opening located at the distal end, a neonatal thermostat is inserted into the hole, thereby closing the opening of the MRD hole. The closure assembly includes (i) an array of distal and proximal sealing walls (both generally perpendicular to the longitudinal axis and upward and downward), and (ii) a length that points up and down. And a recess between the walls having a width from distal to proximal (each of the proximal and distal walls has a notch in the opposite direction, and in the recess, the ratio of length to width is a predetermined At least one U-shaped line having a value greater than n). [Selection] Figure 3D恒温装置の閉鎖アセンブリは、遠位端および近位端を有するＭＲＤの長手方向軸に沿って伸びる開いた孔を有する磁気共鳴画像診断装置（ＭＲＤ）の開口を閉じるように構成され、孔は近位端に位置する開口によって成端し、孔の中に新生児の恒温装置が嵌入され、それによって、ＭＲＤ孔の開口を閉じる。閉鎖アセンブリは、（ｉ）遠位および近位の封止壁（両方とも長手方向軸に対してほぼ垂直であって、上向きそして下向きである）のアレイ、および（ｉｉ）上下に向く長さを有し、そして遠位から近位に向く幅を有する壁の間の凹部（近位壁および遠位壁の各々は反対方向に切り欠きを備え、そして凹部において、長さと幅の比率は所定の値ｎより大きい）を有する少なくとも一つのＵ字形管路を備える。【選択図】図３Ｄ
