Abstract:

The bone segmentation process is a method by which engineers can extract bone tissue  using image processing algorithms such as threshold algorithm, region Growing algorithm or recursive Gaussian algorithm, on patients’ MRI (Magnetic resonance imaging) or CT (Computer Tomographic) scans to obtain virtual models on which to perform virtual simulations using FEM (Finite Element Method). In biomechanics such studies represent an important step in determining  the mechanical behavior of various human anatomical parts, especially for the bone joints, because  the results obtained can be used to improve endoprosthesis and increase their lifespan. 
This paper aims to virtually analyze the mechanical behavior of a female patient with hip joint  arthritis by using CT scans in order to perform bone segmentation in dedicated software such as ScanIP Simpleware to extract the pelvis and the femur as an individual CAD (Computer Aided  Design) part, and to perform virtual simulation at different loads corresponding to a certain body  weight in order to observe how the patients’ unhealthy hip joint is affected in the event that it would gain weight.
