Morphometry

 

quantitative description of the relief of the earth’s surface. The basic morphometric indexes are numerical measures of relief forms: linear, areal, and volumetric measures, absolute and relative elevations of individual geomorphological regions, the depth and density of dissection, and abstract indexes (coefficient of meandering of a river channel, coastline, and the like). Morphometric data are usually obtained by processing topographical maps, but the use of aerial photographs is also possible (employing stereophotogrammetric methods). Special morphometric maps or sets of maps are compiled on the basis of the measurements and computations made. Morphometric data are essential for planning structures, roads, steps to combat erosion, and the like.

Grids (10 x 10 cm) with 36 equal subdivisions were also superimposed on multiple fields from each myoma and used to count the number of myoma cells per grid, as described previously.[16] The relative proportion of cross-sectioned (XS) and longitudinally sectioned (LS) myoma cells was monitored when selecting photographs from each myoma for morphometry, since a relative preponderance of one or the other might bias the results.
Chaware et al conducted a research to study the morphometry of spleen, out of 111 studied spleens, 61.2% spleens were wedge shaped.
Not only 3 dimensional structures such as skull and bone but also 2 dimensional structures such as wings can be compared by means of geometric morphometry. The reliability of the landmark data obtained from 2 dimensional structures is quite high due to technical faults.
Therefore, both patellar morphometry and patellofemoral implant design(s) can influence the physical stress distribution within the unit and particularly following total knee arthroplasty (TKA) [9-14].

The superior temporal gyrus GMV reduction has 100% replicability with the region of interest approach, particularly anteriorly, and voxel-based morphometry concentration studies have repeatedly observed temporal lobe reduction [72-78], which might be specific to schizophrenia since it differentiates patients with schizophrenia and those with bipolar depression.
Hence, any imbalance in the equilibrium of maternal health, placental morphometry, or fetus leads to adverse pregnancy outcome and long-term risk of chronic diseases in the newborn.
Although there have been made a large number of studies on cervical vertebrae in the literature, it has been noted that there are few studies including detailed morphometry of cervical vertebrae conducted in the Turkish population.
Neurodiagnostics industry may be explored by technology as neuroimaging technologies that may further include Nuclear Medicine Imaging (SPECT, PET), Magnetic Resonance Imaging (MRI), Computed Tomography (CT), Electroencephalography (EEG), Near Infrared Spectroscopic Imaging (NIRS), Voxel-based Morphometry (VBM), and Magnetoencephalography (MEG) in vitro diagnostics, and neuroinformatic.
