Tensor-based morphometry (TBM) is an image analysis technique that measures brain structural differences, cross sectional differences or changes over time in repeat scans, from the gradients of deformation fields that align one image to another. TBM may be applied to cross-sectional MRI data for local volumetric comparisons, based on nonlinearly registering individual brain scans to a common an...

Open cell polyurethane foams are often used as cancellous bone surrogates because of their similarities in morphology and mechanical response. In this work, open three different densities characterized from morphometric perspectives. The analysis micro-computed tomography images has revealed that the high density present greatest inhomogeneities. Those inhomogeneities promoted failure location....

This chapter covers selected aspects of the segmentation and measurements of spatial or temporal features (i.e. morphometry) of biological objects in biomedical (non-optical)1 and microscopic images. The term measurement refers to a succinct quantitative representation of image features over space and time. This implies the application of the act of geometric measurement to the raw imaging data...

Evaluation of atherosclerotic plaque composition and morphometry may yield insight into plaque biology and the mechanisms of plaque-associated thrombosis. Analysis of intravascular ultrasound radiofrequency (IVUS-RF) backscatter signal is one technology that provides in vivo assessment of both atherosclerotic plaque composition and morphometry. We summarize three different approaches to IVUS-RF...

the objective of the current study was to determine the anatomical features of the auditory ossicles inhamster. twenty temporal bones from 10 adult hamsters, weighing 275-300 g were used. after dissectingthem, the features of the ossicles were assessed with an ocular micrometer and photographed by astereomicroscope. finally, all data were evaluated and analysed using the sigma statt software. t...

size at sexual maturity and patterns of somatic growth are important aspects of reproductive history of crab. the main purpose of this study is to provide an estimate for the onset of morphological sexual maturity in mangrove crab, opusia indica from a population located in korangi creek intertidal mud flat (karachi, pakistan) based on relative growth. the crabs were monthly collected through q...
