If you take time to understand these definitions, standards and testing methods, you’ll be able to determine the accuracy of CT in your specific application.
I often hear, “How accurate can this be measured using CT?” For CT accuracy and precision should be considered together. For accuracy versus precision, picture a target.
On the upper left the shots are scattered, relative to the lower right, so precision and accuracy are low. The top right shows a “good grouping,” all close to each other but not close to the center. On the lower left all are around the center, some scattered inside the second ring showing high accuracy but low precision.
