Answer Details
The process of detecting a pin mistakenly swallowed by a child is X-ray.
X-ray is a diagnostic imaging tool that uses high-energy radiation to produce images of the internal structure of the body. In the case of a child swallowing a pin, an X-ray can be used to locate the position of the pin and determine if it is causing any harm. The X-ray produces a picture of the inside of the body, allowing medical professionals to see the location and position of the pin, and make any necessary medical decisions based on that information. So, X-ray is a diagnostic tool, not a therapy or a tool for crystallography or mammography.
