X-ray digital photography equipment DR, does the chest move or make any noise when exposed under the board?

You worry too much, the sound of the board is in the fine-tuning position, which is adjusted by remote control. The exposure is audible, but small. The exposure time of chest radiographs is only 0. 1 sec, and theoretically, it is possible to continuously shoot 1700 chest radiographs to reach a dangerous value. DR examination is the most basic examination. The radiation of CT is much larger than that of Dr. Don't do it easily. MR (nuclear magnetic resonance) is harmless.
