8, we show the reconstruction of a randomly chosen two-dimensional (2D) binary pattern of size 128 x 128 x 1 voxels
. The reconstruction and the original pattern are visually identical, with a root mean square deviation of 2.8 kg/[m.sup.3].
When the nodal enhancement function value [E.sub.ball] of the voxel
is larger than the threshold [T.sub.E], these voxels
are selected as the nodule initial seed.
A general linear model (GLM) is commonly used for statistical assumptions of brain activation maps that convert a voxel
time series into a space defined in the design matrix spanned by a set of basis vectors (3).
In addition, extreme positive deviations were significantly higher among the controls (1.14% of voxels
), compared with schizophrenia and bipolar patients (0.83% for both).
* According to the index table, we obtain the boundary voxels
, which have an intersection with the isometric surface.
The imaging protocol varies depending on the field of view (FOV), voxel
size, scan time, milliampere and kilovolt settings, sensor sensitivity, and patient immobilization methods.
The proposed approach is carried out voxel
, and pure voxels
were identified and extracted using a plug-in called Pure Voxel
Extraction (PVE), which was used to analyse the variability of radiodensity of one voxel
with the mean of the values of a 124-voxel neighborhood (window of 5 x 5 x 5 voxels
), as proposed by Elliot & Heck (2007a).
LH Histogram based method computes low and high values of each sample voxels
which are labeled as FL and FH respectively.
To investigate significant differences of the regional VMHC between the HPs and the HCs, a two-sample t-test after correction with the 3dClustSim program (P <0.01, cluster sizes > 85 voxels
) was performed by AFNI software (https://afni.nimh.nih.gov/pub/dist/doc/program_help/3d ClustSim.html).
Binary masks for each of the 10 ROIs were subsequently created in the automated pipeline before applying it on the processed images to collect SUV voxels
. Each voxel
from the labelled ROIs obtained from segmentation was used in this process.
Differences among voxels
were assessed with the Kruskal-Wallis test and the Mann-Whitney U test with the level of significance set to 5%.
The resulting images had 91 x 109 x 91 voxels
with a voxel
size of 2 x 2 x 2 [mm.sup.3].
