(b) Methodology:
(Figure 1 ).
(c) Software's Used:
MIMICS 10.01software is used to view the collected CT scan data of the patient
and importing these images for the generation of the 3D model of the patient's
humerus bone. When the model has been created it is meshed, but the limitation is
that it only has a shell. So to give it a solid form ABAQUS 6.10 software is used
and volumetric meshes are created. ANSYS 14 software is used for the FEA.
(d) Segmentation:
Medical images from the CT or MRI consist of the grayscale information. The
required part is obtained by segmenting the image. Various tools are used for
segmentation. They are: thresholding, region growing, and calculate 3D [ 4 ].
(e) Thresholding:
Thresholding is performed to create a segmentation mask. It classifies all pixels
within a Hounsfield as a same color or a mask. A lower threshold is used for the
segmentation of soft tissue and a higher one is used for the segmentation of bone.
The grey values were defined for selecting a region of interest. The specific area
was selected by delineating the grey values.
