CT Scanner Part Inspected with Radiography
Computed Tomography (CT) is an x-ray procedure that uses computers
to generate cross-sectional views and three-dimensional images of the
internal organs and structure of the body. CT can see inside parts of
the body that cannot be seen on regular x-ray examinations.
The value of CT imaging is that it shows bone, organs and blood vessels
with great clarity. Radiologists interpret the scans to help diagnose
cancers, cardiovascular disease, infectious disease, trauma and musculoskeletal
disorders.
The CT scanner is a large machine with a doughnut-shaped center. The
patient lies still on a table that moves into the opening in the center
of the unit.
Inside the machine, a thin x-ray beam rotates around the patient’s
body to produce the images. Each time the x-ray tube and detector circle
around the patient and the x-ray passes through the patient’s
body, the image of a thin section or a slice of the body, is acquired.
These images are then compiled by a computer to show a cross-section
of body tissues and organs.
At LTI, we are able to x-ray a major component of the CT unit for our
customer, Boose Aluminum Foundry Co. Radiography is used to determine
if there is shrinkage, cracking, porosity or other internal flaws that
would affect the performance of the machine. Each piece is approximately
6 ft. in diameter and 500 lbs., and easily fits into our 20 ft. by 20
ft. radiography room.
