LumVBCanSeg: A Lumbar Vertebral Body Cancellous Bone Segmentation Dataset
<p>To address the lumbar vertebral body cancellous bone segmentation problem, we propose a new dataset called LumVBCanSeg. The entire dataset consists of 185 lumbar CT scans acquired using multiple CT scanners, including the two manufacturers(Philips, Siemens). All data were obtained at ShengJing Hospital of China Medical University. Cases involving vertebral fractures, metal implants, bone tumors and foreign materials were omitted. All data were resampled to an isotropic resolution of 1mm × 1mm × 1mm. Each lumbar 3D CT image has a corresponding segmentation mask annotated at voxel level using the medical image annotation package Pair. Annotations cover five lumbar vertebral body cancellous bones from L1 to L5, with labels ranging from 1 to 5. All annotations were performed by 3 physicians followed by further refinement, dismissal or approval by one physician with more than 30 years of experience in lumbar imaging. </p>

Combination of Bone Marrow Concentrate and Iliac Cancellous Bone Graft in Alveolar Cleft Grafting
ClinicalTrials.gov study NCT04414423. IPD Sharing: NO. Countries: 1. Publications: 3.
METHODS. Bovine ilia were used in the simulations because their histological structure (a fibrolamellar cortex overlying cancellous bone26) was found to match that of the Triceratops ilium. Bone sections 10 x 50 x 縠 3.0 cm with cortices ranging from 0.5 to 5.5 mm in depth (the range of initial cortical-thickness estimates based on gross morphology) were mounted on a servohydraulic mechanical loading frame (MTS Bionix, Minneapolis) and penetrated with an aluminium-bronze T. rex tooth replica. The replica was cast from an actual adult T. rex maxillary tooth, after casts made from some ofthe deeper bite marks revealed the size and shape of the teeth that had impacted the pelvis8 • The replica was penetrated into the ilia sections at 1 mm s-1 to a depth of 11.5 mm, equivalent to the maximum depth of the deepest ilium bite mark8 • Forces were measured with an MTS 25 N strain-gauge-based axial load cell accurate to 0.2%. The forces increased with increasing penetration depth even after the cortical layer had been perforated and the underlying cancellous bone was being crushed. The increase in force with penetration depth is attributed to a greater cortical surface area coming into contact with the semi-conical penetrator tooth as it descended through the ilia. in Bite-force estimation for Tyrannosaurus rex from tooth-marked bones

Quantifying Cancellous Bone Structural Changes in Microgravity: Axial Skeleton Results from the RR-1 Mission
Objective of this study was to further validate bone degradation in microgravity as site-specific and preferential to weight bearing bone. An objective of this study was to further understand the role of the mechanical environment in controlling the process of bone remodeling, namely local formation and resorption to maintain a healthy structure. These data from the lumbar 4 bones of Rodent Research-1 mission aboard the International Space Station, are unpublished, and were presented at the 2016 meeting of the American Society for Gravitational Space Research. This dataset derives results from the micro–computed tomography (mCT) assay.
