Computer Tomography – Precise Measurement with Computer Tomography-2

Other geometric artifacts arise from scattered radiation, the orientation of the rotary axis in the image, and other effects (Fig. 42). Analytical capture and correction of these complex interrelationships is barely possible at the moment, considering that the associated parameters […]

Computer Tomography – Precise Measurement with Computer Tomography-3

Figure 43 illustrates the principle of the described correction method. The geometric artifact arises because, when rotating the rectangular measured object, shorter radiographic lengths occur at the corners than in the middle. This leads to an apparent spherical shape during […]

Computer Tomography – Precise Measurement with Computer Tomography-1

To be able to measure the shape and position of a measured object with sufficient precision, it is necessary to correct systematic errors in tomography. Several process-related effects lead to these systematic deviations. Common to all of them is the […]

Computer Tomography – Multisensor Coordinate Measuring with X-Ray Tomography-4

Operation of the measuring device is done by the measurement software which is also used for optical-tactile coordinate measuring machines. The software modules needed for tomography measurements are also integrated in WinWerth® (Fig. 40). The entire measurement process using computer […]
