Constructing High-Order Signed Distance Maps from Computed Tomography Data with Application to Bone Morphometry

  title={Constructing High-Order Signed Distance Maps from Computed Tomography Data with Application to Bone Morphometry},
  author={Bryce A. Besler and Tannis D. Kemp and Nils Daniel Forkert and Steven Kyle Boyd},
An algorithm is presented for constructing highorder signed distance fields for two phase materials imaged with computed tomography. The signed distance field is high-order in that it is free of the quantization artifact associated with the distance transform of sampled signals. The narrowband is solved using a closest point algorithm extended for implicit embeddings that are not a signed distance field. The high-order fast sweeping algorithm is used to extend the narrowband to the remainder of… 
Bone Adaptation as a Geometric Flow
Recognition of bone adaptation as a geometric flow permits the recruitment of mathematical and numerical developments over the last 50 years to understanding and describing the complex surface of bone.


Local Morphometry of Closed, Implicit Surfaces
A fast, simple embedding procedure for accurate local morphometry as the zero crossing of the Gaussian blurred binary image is presented and enables an improved local and global evaluation of curvature for purposes of morphometry on closed, implicit surfaces.
High-Order Signed Distance Transform of Sampled Signals
A large constant, linear time complexity high-order signed distance transform for arbitrary dimensionality sampled signals is developed based on the high order fast sweeping method and cannot attain arbitrary order of accuracy and is limited by the initialization method and nonuniqueness of the problem.
Marching cubes: A high resolution 3D surface construction algorithm
We present a new algorithm, called marching cubes, that creates triangle models of constant density surfaces from 3D medical data. Using a divide-and-conquer approach to generate inter-slice
Accuracy limits for the determination of cortical width and density: the influence of object size and CT imaging parameters.
The accuracy of computed tomography measurements in assessing cortical bone is analysed to determine the dependency of thickness and density measurements on the true width and density of the cortex and on the spatial resolution in the CT images using two optimized segmentation methods.
Non-invasive bone biopsy: a new method to analyse and display the three-dimensional structure of trabecular bone.
The results showed that surface representation and visualization in combination with a multiple thin-slice measuring technique are valuable tools in studying three-dimensional bone architecture.
Artifacts of Quantization in Distance Transforms
This work describes and investigates an artifact present in distance maps computed from sampled signals, namely, sampling reflects through the distance transform causing quantization in the resulting distance map.
Guidelines for assessment of bone microstructure in rodents using micro–computed tomography
Standard nomenclature, outlined in this article, should be followed for reporting of results of µCT‐derived bone morphometry and density measurements.
Three‐dimensional mapping of cortical thickness using Laplace's Equation
A novel, computerized method of examining cerebral cortical thickness is presented, which presents graphical results that map cortical thickness everywhere in a normal brain, and shows global variations in cortical thickness consistent with known neuroanatomy.
