It can be used for detecting or confirming the presence of a tumor inside the human body, and providing information about the size of the tumor and whether or not it has spread.
CT scans are used to image a wide variety of body structures and internal organs.
Positron Emission Tomography (PET) scans are used in hospital mainly to detect cancers, especially cancers that have metastasised or spread into surrounding tissue.

It helps because seismic tomography is a technique used to look beneath Earth's crust so, they can technically "see" where oil deposits are located.
X-ray computed tomography was created in 1972.
