In medical diagnostic imaging, an X-ray CT scanner or a MRI system have
been widely used to examine 3D shapes or internal structures of living
organisms or bones. However, these apparatuses are generally very
expensive and of large size. A prior arrangement is also required before
an examination, and thus, it is not suitable for an urgent fracture
diagnosis in emergency treatment.
In this paper, we have proposed a method to estimate a patient-specific 3D shape of a femur from only two 2D radiographs using a parametric femoral model.
In addition, this paper introduces experiments using two radiographs of living bodies in a clinical setting. Experimental results show that obtained accuracy for shape estimation of four patients$’$ femurs is 0.8 to 1.1mm. |
