Principles of CT Operation: What is industrial cone beam computed tomography?

The specimen placed on a rotation table is irradiated by a cone-shaped X-ray beam so that a magnified X-ray image is produced on a detector. Generating volumetric data using industrial cone beam CT starts with the acquisition of a series of two dimensional X-ray images while progressively rotating the sample step by step through a full 360° rotation. These projections contain information on the position and density of absorbing object features within the sample. This accumulation of data is then used for the numerical reconstruction of the volumetric data.
