The Role of Uncertainty of Measurement in CT

In a CT system, X-ray photons emitted from an X-ray tube will travel through the object and hit a detector. The detector senses the dose at each pixel of the detector area. This creates digital images while the object is rotated. The reconstruction software calculates virtual slices based on the dose at each location from different angles. The result is called a tomogram. Each pixel in the tomogram represents a density of material, a voxel.

The Future Is Now

You might be surprised to know cast metal products can be found in 90 percent of manufactured goods and equipment throughout the world. From critical components for aircraft and automobiles to home appliances and surgical equipment, cast metal products play an important role in today’s economy especially in the United States. The U.S. is the world’s largest supplier, shipping $18 billion worth of products annually (according to the Office of Industrial Technologies report, Metal Casting – Industry of the Future).
