ZEISS**Kunshan Youshuo today introduces you to a number of factors affecting the accuracy of industrial CT, the following are the main aspects:
1. Workpiece material.
Different materials absorb X-rays differently, and the different absorption rates will also affect the quality and quantity of X-rays entering the measurement range, which will have an impact on the imaging effect. The characteristics that vary from material to material can make industrial CT have different accuracy performance on different materials. For high-absorbing materials, the imaging effect of industrial CT is more susceptible to diffraction and scattering, which reduces the imaging quality.
2. Scan parameters.
Scanning parameters are another important factor affecting the accuracy of industrial CT. The relevant parameters of industrial CT scanning include: voltage and current of the X-ray source, scanning overlap ratio, reconstruction algorithm, etc. Changes in these parameters may lead to changes in spatial resolution, contrast resolution, measurement error, and other metrics. For example, increasing the voltage of the X-ray source can improve the quality of the image, but it can also increase the radiation dose, creating a safety hazard.
3. Equipment performance.
The performance of industrial CT equipment also has a great impact on accuracy. The focal size of the ray source, the resolution of the detector, the mechanical structure, the reconstruction algorithm, etc., can all have an impact on the accuracy of industrial CT. Therefore, it is very important to choose high-quality industrial CT equipment.
4. Human factors.
Human factors may also affect the accuracy of industrial CT. For example, the skill level and experience of the operator, the operating procedures and methods, as well as the interpretive ability and the degree of understanding of the accuracy elements may affect the accuracy of the industrial CT. Especially in the areas of data acquisition, scan control, imaging reconstruction, and geometric calibration, if operating procedures and standard methods are not strictly followed, the accuracy can also deteriorate.
5. Environmental conditions.
Environmental conditions can also have an impact on the accuracy of industrial CT. For example, environmental factors such as temperature, humidity, dust, and vibration can all have an impact on the stability and accuracy of a system, especially in sensitive inspection tasks.
