In this paper we present a semi-automatic method for femoral bone positioning after 3D image reconstruction from Computed Tomography images. This serves as grounding for the definition of strict axial, longitudinal and anteriorposterior views, overcoming the problem of patient positioning biases in 2D femoral bone measuring methods. After the bone reconstruction is aligned to a standard reference frame, new tomographic slices can be generated, on which unbiased measures can be taken. This allows not only accurate interpatient comparisons but also intra-patient comparisons, i. e., comparisons of images of the same patient taken at different times. This method enables medical doctors to diagnose and follow up several bone deformities more easily.
