A Study of Prototype Hip Joint Model With R P M by X-ray Films

摘要

The method of forming 3-D data from X-ray CT is popular. This stud is to make a 3-D model of hip joint from X-ray images. The advantages of this emthod are X-ray radiation level and the patient suffering less. THe patient 3-D data we obtaiend come from we combine the sample data with using 3-D emasuring machine and outline data form X-ray films by using digitizer. The measurement of sample data can be obtaiend with a probe of tactile sensor of static capacitance type. The measuring method is point-to-point method. The patient 3-D data re made from fundamental data which interpolation of the sample data and the outline data. Finally we rmade a patient femur bone 3-D data represented by about 53000 patch data which contain apex coordinates and the vector normal of surface from 4 X-ray images.
