Medical imaging device

The invention provides a medical imaging device which can more easily see a shot object from the outside compared with the condition that the number of supporting columns is two, wherein the supporting columns have to be thickened. The CT apparatus includes: a radiation source that irradiates radiation; a radiation detector that detects radiation; a frame which is a ring-shaped frame on which the radiation source and the radiation detector are mounted, and in which the subject is positioned in the cavity; and three pillars that hold the frame so that the frame can be lifted in the vertical direction. 本发明提供一种相较于不得不加粗支柱的结构的支柱为两个的情况更容易从外侧视觉辨认被摄体的医用图像摄影装置。CT装置具备：放射线源，照射放射线；放射线检测器，检测放射线；框架，为安装有放射线源及放射线检测器的环状框架，并且被摄体被定位到空腔；及三个支柱，将框架保持成能够在铅垂方向上升降。
