Correlation coefficients and clustering enable a visualization and assessment of the experiment structure based on global expression behavior.
3D image of A2, A3, and A4 could not be reconstructed for the following reasons: (1) firstly, low enhancement of A2, A3, and A4: one of the most important parameters to minimize partial volume effects in improving spatial resolution in CT angiography is a contrast density of >250 HU, which enables a continuous visualization of the arteries as small as 0.5 mm in diameter [6].
The higher axial resolution (3 µm) of HD-OCT probably enables a better visualization of the DEJ compared to other non-invasive technologies with cross-sectional imaging such as HF-US and conventional OCT.
Longer wavelengths overcome much of the scattering of light on choroidal vasculature, thus it enables a more exact visualization of the choroid.
These data are subsequently converted to pixels and an image is then built-up, enabling a spatial visualization of all phenomena occurring in the sample.
To additionally stabilize the video-level controller, asymmetric control behavior is imposed, so that when a low video level is measured (dark object entered the area of interest), the controller responds rapidly and the image intensity increases to enable a better visualization of the object of interest.
Therefore, decalcification was used here to remove the mineral phase; it enabled a good visualization of the vascular network without shrinkage.
Tissue microarray sections are counterstained with hematoxylin, enabling a nonspecific visualization of microscopic structures, in addition to the binding of the antibody that results in a dark-brown stain 31.
As such, it makes processing entire pullbacks feasible, enabling a 3D visualization of the tissue distribution with the vessel wall (Fig. 8 ) potentially improving diagnostic and therapeutic value of these data sets.
Stampanoni et al. analysed five mastectomy samples using phase-contrast mammography and found that the fused images created from the grating-based absorption-, phase- and dark-field signals enable a better visualization of small tumours, skin infiltration and differentiation between scars, healthy tissue and invasive cancer [ 16].
