2. Scanning
If you've ever had a CT scan at a hospital, this is exactly the same process, except our scans were made in a particle accelerator and are much higher resolution.
Scanning involves taking hundreds to thousands of X-ray photographs of the object from different rotational angles. Typically this is done by having an X-ray source on one side of the object, and an X-ray camera on the other side, and rotating the object 360° on a platform.
