چکیده
Repeatability of thickness measurement Introduction • Goal: construct reliable 3D model of knee cartilage from partial laser scans. • Off-the-shelf ICP yield unreliable solutions because of sensing error and sampling error. • Our contributions: • Reduce sensing error using bilateral Gaussian smoothing • Reduce sampling error using point-to-mesh correspondence • Fuse multiple scans following maximum spanning tree of overlaps

Accurate Measurement of Cartilage Morphology Using a 3D Laser Scanner
We describe a method to accurately assess articular cartilage morphology using the three-dimensional laser scanning technology. Traditional methods to obtain ground truth for validating the assessment of cartilage morphology from MR images have relied on water displacement, anatomical sections obtained with a high precision band saw, stereophotogrammetry, manual segmentation, and phantoms of kn...
متن کاملKnee adduction moment relates to medial femoral and tibial cartilage morphology in clinical knee osteoarthritis.
The objective was to determine the extent to which the external peak knee adduction moment (KAM) and cumulative knee adductor load explained variation in medial cartilage morphology of the tibia and femur in knee osteoarthritis (OA). Sixty-two adults with clinical knee OA participated (61.5 ± 6.2 years). To determine KAM, inverse dynamics was applied to motion and force data of walking. Cumulat...
متن کاملLocalized inter-subject comparison of knee cartilage thickness, T2 and T1ρ: generating an atlas of the knee
Introduction and Motivation. In osteoarthritis of the knee (knee OA), different morphological, molecular, and biochemical biomarkers for predicting or evaluating the degree of knee OA have been investigated. It has been observed that with progression of knee OA morphometric parameters such as cartilage thickness and volume decrease; and that molecular and biochemical cartilage properties such a...
متن کاملHistomorphometrical Changes on the Knee Joints of Male and Female Rats After Moderate Exercise Program
Introduction: Osteoarthritis (OA) is one of the most common joint diseases that is accompanied with cartilage loss and finally leads to joint destruction. The most common joint that is affected in OA is the knee joint. Knee joint OA may lead to significant illness. Methods: The effect of excessive running load on the development of knee OA was investigated in rats. This study aimed to ev...
متن کاملOptimal sampling of MRI slices for the assessment of knee cartilage volume for cross-sectional and longitudinal studies
BACKGROUND MRI slices of 1.5 mm thickness have been used in both cross sectional and longitudinal studies of osteoarthritis, but is difficult to apply to large studies as most techniques used in measuring knee cartilage volumes require substantial post-image processing. The aim of this study was to determine the optimal sampling of 1.5 mm thick slices of MRI scans to estimate knee cartilage vol...
