a computer accessible memory operational to store a three-dimensional array of data elements describing multiple anatomical features of a subject, each of the data elements having associated therewith positional data and a separate parameter value; and

a processor, operatively coupled to the computer accessible memory, operational to identify any data elements in the three-dimensional array having an associated parameter value satisfying a predefined threshold value associated with at least one anatomical feature, the processor further operational to acquire from the computer accessible memory, positional data associated with the data elements identified as having an associated parameter value satisfying the predefined threshold value and store the acquired positional data in a computer memory;

wherein the processor is further operational to generate, from the acquired positional data stored in the computer memory, a visually displayable three-dimensional point cloud model of at least one anatomical structure including a bony anatomical structure having a first plurality of points in the three-dimensional point cloud model which define an exterior perimeter of the bony anatomical structure and a second plurality of points in the three-dimensional point cloud model which define at least one feature interior of the exterior perimeter of the bony anatomical structure, both the first plurality of points and the second plurality of points in the three-dimensional point cloud model being simultaneously visually discernable;

wherein the first plurality of points in the three-dimensional point cloud model define an exterior perimeter of cortical bone of the bony anatomical structure; and

wherein the second plurality of points in the three-dimensional point cloud model define regions of cancellous bone interior to the exterior perimeter of cortical bone in the bony anatomical structure.
