Establishment of the method of computer orbital three dimensional measurement

Objective Establishment of the method of computer orbital three -dimensional measurement. Method Using three - dimensional CT imaging and computer imaging processing, combining the program of orbital three - dimensional measurement. A comparetive study between the direct measurement and the three - dimensional imaging measurement was carried out on thirty orbits of fiftween adult skull samples. Results Nosignificant difference was detected between the results of the direct measurement and the three-dimensional imaging measurement, the average bias error of various measuring parameters is less than 5%,the measuring guidelines of the orbital three - dimensional measurement are utility and reliable, may allow to reflect really the shape and size of the orbit. Conclusion The results of the orbital three -dimensional imaging measurement is more accurate and precise, the method can satisfied the clinical needs of orbital measurement.
