An imaging apparatus such as a CT makes it easy to move and install by reducing the size and weight, reducing the power consumption, and reducing the exposure, and is useful for early detection and treatment of cancer and other diseases. An imaging device having a gantry that moves forward or backward in the body axis direction on a gantry and having a light source, a light source drive circuit, and a rotation unit interface in a rotating unit in the gantry, and an image in the gantry in a stopped state of the gantry The imaging data recorded in the memory is read out to the host interface at a predetermined position on the gantry. [Selection] Figure 1【課題】ＣＴ等の撮像装置の小型・軽量化、低消費電力化、低被曝化により移動や設置を容易にし、癌その他疾病等の早期発見と治療に役立てる。【解決手段】架台上を体軸方向に前進又は後退するガントリを備え、ガントリ内の回転部に光源、光源駆動回路、及び回転部インターフェースを有する撮像装置、及びガントリの停止状態においてガントリ内の画像メモリに記録された撮像データを架台上の所定位置にあるホストインターフェースへ読み出す。【選択図】図１
