Computed Tomography as a Nondestructive Testing Method
Applied Technical Services stands at the forefront of industrial CT scan companies by employing the method’s versatility and precision to serve clients in a variety of applications. More formally known as computed tomography, CT represents the most powerful method of nondestructive testing currently available. While people are more familiar with the method’s medical uses (which allows doctors to detect and locate issues ranging from internal bleeding to cancerous tumors), CT scanning has seen increasing use in industrial applications. Companies can request a CT scan on their parts, components, and assemblies to achieve a variety of goals, such as:
How the Method Works
Being an offshoot of traditional radiography, the computed tomography process bears some similarities: CT scans produce tomograms (black-and-white images also known as slices that depict a cross-sectional view of the subject as if bisected) by exposing a sample part to a barrage of X-Rays which are captured by a detector mounted opposite. The major differences between the methods present themselves in the number of images produced by a single test and how those images can be used.
At the beginning of a CT scan, a pedestal inside the chamber moves the subject into the path of the X-Rays. This platform will then maneuver the sample subject so that a new angle faces the projector, allowing the next slice to capture a different view of the object. CT requires that the machine repeat this process hundreds or even thousands of times — exposing the subject at every conceivable angle, rotation, tilt, and elevation. Once they have this collection of 2D images, our technicians then compile the slices into a single, 3D X-ray model.
The sheer number of slices used to create this model ensures that it is a rich, highly detailed representation of a subject’s every surface, both inside and out. Our technicians can convert the model produced by the CT process (called a voxel-based point cloud) into a CAD model for additional utility, such as taking measurements or providing a copy to the client.
