Figure 7.7. A finite element model of a bone specimen in compression. This model was created by converting the voxels from a microcomputed tomography scan into individual bone elements. Loads can then be applied to the model to understand the stresses that are created in the bone tissue. Figure 7.7. A finite element model of a bone specimen in compression.

Figure 6 X-ray microcomputed tomography. An axial cross-section through a freeze-dried 15-minute swollen high-amylose starch pellet, in which variations in X-ray attenuation provide evidence of an outer surface membrane. The pellet size is 3.0 (height) x 3.3 (width). The membrane thickness is 300 pm on the right and left edges (at mid height) and 450 pm at the top and bottom sides of the pellet. The smooth layer ranges from 130 pm on the right and left edges to 200 pm on the top and bottom sides. Source From Ref. 159. Figure 6 X-ray microcomputed tomography.

There are currently many methods to evaluate UHMWPE wear, including direct [7, 8], gravimetric [9, 10], radiographic [11-13], optical [14], fluid displacement [15], and more recently, microcomputed tomography (microCT) based [16, 17]. All of these techniques have their own... [Pg.511]
