Description
Summary:Virtual volume. pCT uses a volumetric method. From a series of 2-D projection images, taken from several rotational positions divided around 360°, the 3-D structure of the object is determined from its x-ray absorption. This principle is shown in Figure 3. A beam cone is emitted from a point-formed rathation source (focal point of the microfocus x-ray tube), fielded by the real-time detector and then evaluated.
