    摘要: A method of imaging a body part of a patient can include acquiring a first, second and third sets of image data from a first, second and third anatomical reference areas. The first, second and third sets of image data can then be compiled to produce a legend of the body part. The legend can have positional information of the first, second and third anatomical reference areas. A fourth, fifth and sixth sets of image data of the first, second and anatomical reference areas can be acquired. The fourth, fifth and sixth sets of image data can have increased image information relative to the first, second and third sets of image data, respectively. The locations of the fourth, fifth and sixth sets of image data relative to the first, second and third sets of image data can be correlated using the legend to determine a characteristic of the body part.

    摘要: The present invention discloses a method of making a bearing component of a medical implant suitable for use as an artificial joint, the method comprising:
    - preheating a crosslinked polymeric bulk material to a temperature 80°C and below the melting point of the polymeric material, wherein the bulk material is characterized by having an axial direction and a transverse direction orthogonal to the axial direction and is further characterized by a dimension d1 in the transverse direction;
    - applying deforming pressure to the bulk material to change the dimension from d1 to d2, where d2 is less than d1; and
    - machining the bearing component from the extruded bulk material, wherein the load bearing axis of the bearing component corresponds to the axial direction of the crosslinked bulk material.
    Preferably, the crosslinked polymeric bulk material is crosslinked ultra high molecular weight polyethylene (UHMWPE).
