The procedure of chest X-ray is mainly done by having the patient stand on a pedal, usually in a standing position. The patient’s back is against the test pillar, and he/she is still, cooperating with the physician to make the corresponding movements. 1. Steps before chest X-ray: patients need to take off their metal jewelry before chest X-ray, take off some foreign objects such as outerwear and pendants that will have an impact on the results of chest X-ray, and the key areas can be protected by lead plates. 2. Steps in chest X-ray: patients should maintain a good state of mind and not be overly nervous. During the chest X-ray examination, the patient should stand facing the X-ray bulb tube, with his back against the test pillar, and inhale deeply, exhale deeply and hold his breath according to the instructions of the physician. During the examination, the patient should keep still and do not move, so as not to blur the image. Patients need to actively cooperate with the doctor to make postural adjustments during chest X-ray. Chest X-ray examination should go to a regular hospital to listen to the arrangements of professional doctors.
