Abstract
The biocompatible lattice structures disclosed herein with an increased or optimized lucency are prepared according to multiple methods of design disclosed herein. The methods allow for the design of a metallic material with sufficient strength for use in an implant and that remains radiolucent for x-ray imaging.
Claims20
A method of increasing lucency in a porous structure, steps comprising:
- generate a bulk volume repeating structure in a form capable of analysis by an analysis tool;
- wherein the analysis tool is configured to analyze multiple variables;
- propagate the bulk volume at some orientation;
- calculate a uniformity of bulk thickness across the structure in a desired direction for viewing;
- iterate across rotations to identify a desired uniformity of bulk thickness;
- and
- capture the parameters and generate a final structure.

A method of increasing lucency in a porous structure, steps comprising:
- identify approximate implant dimensions for the porous structure;
- run a multivariable analysis for uniformity of bulk thickness for a porous structure of the approximate implant dimensions from a desired direction;
- wherein the porous structure is rotated from an origin orientation by at least 90 degrees about x, y and z axes;
- and
- use the multivariable analysis to determine a rotation from the origin orientation that produces a specific lucency characteristic in the desired direction.

A method of increasing lucency in a porous structure, steps comprising:
- generate a bulk volume repeating structure in a form capable of analysis by an analysis tool, wherein the bulk volume is sectioned into the approximate dimensions of an implant type;
- wherein the analysis tool is configured to analyze multiple variables;
- propagate the bulk volume at some orientation;
- calculate a uniformity of bulk thickness across the structure in a first desired direction for viewing;
- calculate a uniformity of bulk thickness across the structure in a second desired direction for viewing;
- iterate across rotations to identify a desired uniformity of bulk thickness in the first desired direction for viewing and the second desired direction for viewing;
- wherein the desired uniformity of bulk thickness in the first direction for viewing is selected from a group consisting of relative disparity and relative dispersion;
- wherein the desired uniformity of bulk thickness in the second direction for viewing is selected from a group consisting of relative disparity and relative dispersion;
- and
- capture the parameters and generate a final structure.
