A beer mug was acquired from Germany during a training visit, and it was decided to use this as an example for dimensional measurement or metrology using X-ray CT. The simple process employs best-fit planes and cylinders in this case to determine the height and diameter of the mug, though any distances or angles could be determined in principle. In this case a plane was fit to the indicated level of 500 ml, and the internal volume measured using a volume analysis tool, as 500.45 ml. We congratulate our German beer mug manufacturers on this accuracy and feel the beer was worth the money.
