Optimizing Defect Detectability

Setting up a computed tomography scan can be a complicated task when trying to optimize defect detectability. There are many parameters that can be adjusted, and many of them have a direct or inverse relationship with other parameters for your scan. Optimizing these parameters can frequently be a process of trial and error, but if you consider the following you can help reduce some of the time spent optimizing your technique. The first thing to consider is the size of the defects and or features that you would like to image. This will have a very large impact on the technique that you use. Ideally you will…
