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.

Exploring Accuracy and Uncertainty in Computed Tomography
There is a range of terminology for CT system accuracy and uncertainty that should be understood when evaluating 3D scanning systems, this blog post illustrates some of those terms, such as Precision and Accuracy, Tolerance, Uncertainty of Measurement, Resolution, Error, and Suitability.

CT for TEI's Technologically Advanced Casting Process
Tooling & Equipment International (TEI) is a global leader in design, engineering and manufacturing for prototype, pre-production and mass production equipment for the casting industry. TEI's core business is manufacturing of prototypes and therefore invested in new, advanced technologies including 3D printing for sand molds, simulation technology, low-pressure casting, CT and X-ray inspection.

Why Variable Detector Position Matters
In this video Dirk Steiner compares two examples of scans at 550mm vs 1100mm detector distance using a micro-focus tube to illustrate how scan speed can be increased, and he shows the impact on image quality and dimensional deviation.

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
).

How Computed Tomography Reveals the Internal Anatomy of Bat Skulls
Abigail Curtis, a postdoctoral fellow at the American Museum of Natural History in New York, demonstrates how computed tomography reveals unexpected scientific insights into bat physiology. X-ray with computed tomography is used to create digital reconstructions of modern and fossilized bat samples.

How It's Made: A Video Introduction to Computed Tomography
Computed tomography (CT) goes light years beyond regular 2-D X-ray technology to deliver accurate three-dimensional images of scanned objects, including their voids and areas of differing density. Jason Robbins, YXLON Senior Product Manager, explains the science of CT in this (fun and nerdy!) educational video.
