Importance of computer aided measurement techniques for the controlling industrial manufacturing and testing technical products with high accuracy, increases more than ever with the general goal of improving the quality of all kinds of manufactured patient products. Rapid development in biomedical techniques demands the application of modern computerized measurement techniques and utilization of measuring devices with new technologies. Especially computer aided co-ordinate measuring technique can be applied to evaluate the shape of non technical structures (objects), such as human limbs or joints with high accuracy. Measurement results create the basis for the improvement and optimization of future work in biomedical techniques and related areas.
