Outer-Boundary Assisted Segmentation and Quantification of Trabecular Bones by an Imagej Plugin

2018
We present a workflow for segmenting and quantifying trabecular bones for 2D and 3D images based on the bone's outer boundary using an ImageJ plugin. This approach is more efficient and accurate than the current manual hand-contouring approach, and provides layer-by-layer quantifications, which are not available in current commercial software.

Trabecular meshwork (TM) migration into Schlemm’s canal space can be induced by acute pressure elevation by ophthalmodynamometer, and observed by spectral domain optical coherence tomography. The goal of this method is to quantify the morphometric response of the living outflow tract to acute pressure elevation in living tissues in situ.

Many animals naturally stop growing upon reaching adulthood, after which they undergo aging or "senescence" until dying. The amount of time between an organism\'s birth and death is called its lifespan, which can be influenced by various biological and environmental factors. By exposing organisms to different growth conditions, scientists can better understand the factors affecting lifespan. Flies and worms are ideal organisms to perform such experiments, given their short generation time and...

This article describes step-by-step methods to automate image-based nuclei quantification using an open-source executable program validated across a range of cell densities. This program provides an alternative that addresses barriers related to cost, accessibility for users with limited technological skillsets, and application-specific validation that may limit utility of existing technologies.
FAQs
These metrics describe different aspects of the same internal architecture. Bone volume fraction indicates how much of the measured region is occupied by bone, while thickness and number characterize the amount and dimensions of individual trabeculae. Separation describes the spaces between them. Considering the metrics together provides a more informative picture of structural organization and its potential mechanical relevance than relying on one value alone.
Connectivity helps indicate how effectively the trabecular network forms a continuous load-bearing structure. A network with altered connections may respond differently to mechanical demands even when another measurement, such as bone volume fraction, appears similar. Quantifying connectivity therefore helps bioengineers relate microscopic organization to load bearing, fracture risk, and changes associated with tissue remodeling.
Remodeling can change the arrangement and proportions of the trabecular network, producing measurable differences in thickness, number, separation, connectivity, or bone volume fraction. Trabecular quantification makes these architectural changes available for comparison across bone conditions, including osteoporosis and other skeletal disorders. The resulting measurements help researchers examine how altered microarchitecture may influence structural performance and fracture risk.
A typical workflow uses computed tomography or micro-computed tomography to image a bone region, segment the trabecular network, and calculate structural metrics. The resulting measurements can then be examined together to characterize the architecture and its mechanical relevance. This sequence connects image-derived structure with questions about load bearing, remodeling, disease-related change, or engineered bone performance.
It is useful when researchers need to evaluate how bone microarchitecture relates to mechanical behavior or disease. Applications include studying osteoporosis and other skeletal disorders, assessing tissue remodeling, and examining structural requirements for bone implants and scaffolds. By providing quantitative architectural measurements, the method supports comparisons between native bone, altered tissue, and engineered designs.
Measurements of bone volume fraction, trabecular dimensions, separation, and connectivity provide structural information relevant to implant and scaffold design. Researchers can use this information to relate an engineered architecture to the organization found in bone and to consider how that structure may influence load bearing. The measurements also support evaluation of whether a design is consistent with desired biomechanical performance.
