Fast and Accurate 3-D Registration of HR-pQCT Images
High-resolution peripheral quantitative computed tomography (HR-pQCT) is a non-invasive bone imaging technology that generates high-resolution 3-D images for quantitatively analysis of the bone micro-architecture. To enable quantitative evaluation of bone changes, accurate alignment between the baseline and follow-up scans of the same individual is necessary. An automatic approach is proposed for fast and accurate registration of the HR-pQCT data. This method significantly improves the efficiency of current HR-pQCT matching procedure, and may contribute to the clinical application and research of HR-pQCT

Title: Registration of 3D tomography images
Usefulness: Registration of 3D tomography images
Summary: Method for facilitating registration of quantitative CT image of a bone of a patient to analyze bone gain/loss. Can also be used for bone registration of a peripheral quantitative CT image, micro-CT image, high-resolution peripheral quantitative CT image, MRI, and positron emission tomography-CT image (all claimed).
Novelty: Method for facilitating registration of quantitative computed tomography image of bone of patient to analyze bone gain/loss, involves registering surface of follow-up image with surface of baseline image such that surfaces are overlapped
