How to take a chest X-ray to ensure that there is no shadow on the left rib?

This inspection requires correct positioning and adjustment of exposure parameters.

1. Correct positioning: When taking the chest radiograph, the client should take a standing position, put his body forward, put his hands on his sides, and keep his body upright. At the same time, the subject's chest should be attached to the wall or flat plate to ensure that the body and chest are completely attached to the camera.

2. Adjust exposure parameters: When shooting chest radiographs, the setting of exposure parameters is very important. If the exposure parameters are not set properly, the image may be blurred or shadowed. Therefore, before shooting, the exposure parameters should be properly adjusted according to the size of the subject and the thickness of the chest.
