Femur Bone

A human femur bone specimen was prepared for 3D modeling using Digital Imaging (DI) and CT scanning techniques. The specimen's attributes include a male, left leg, aged 44 at death, weighing 85 kg, and standing 185 cm tall. DI employed CMM Optical technology from GOM Co., Germany in 2015 to create the initial 3D model, which was later refined as a solid. The inner region of the femur could not be modeled using DI alone; hence, CT scanning was used. This approach modeled only cortical bone tissue and not trabecular tissue. To accomplish this, the entire bone was scanned, and 10mm-spaced sections from the proximal to distal region were created. The DICOM format stored these 2D images, which were then visualized in Photoshop CC. In Solid Works 2013, the 3D model and CT scan cross-section images were imported, and the outer boundaries of each section corresponded to its 3D counterpart. Emptying the sketches with lofted cut modules completed the modeling process, ensuring an accuracy of 0.01mm.
