Attenuation and scatter accuracy, contrast recovery of hot and cold regions of different sizes, and finally, quantification using three calibration phantoms of different sizes have been analyzed.
Specifically, 3D images recorded in the cross-polarized (VH) linear working scheme (Figure 14(a) and 14(c)) evidence better phase measurement accuracy, contrast, spatial resolution (of the order of millimeter at 1.5 m), as well as less phase noise compared to 3D models recorded by using the copolarized (VV) linear working configuration (Figure 14(b) and 14(d)).
Considering the accuracy contrast in the Load-4 condition only is a good control in this context.
We used the GLM to test whether activity in the right-hemisphere fronto-parietal network was significantly modulated by either the load or the accuracy contrast, in either the pre- or post-stimulus period, for each group.
However, little is known about differences in accuracy of contrast injection, the effect of contrast leakage on image interpretation [ 19], the time taken and the discomfort experienced by the patient [ 23, 24] among different radiologists using different techniques.
We found that the MEP contrast was strongly and negatively correlated with the accuracy drop contrast found in Exp1M1right (r = −0.57, p = 0.008; Fig. 4), with a stronger inhibitory response associated with a smaller drop in accuracy and less inhibition with a greater accuracy drop.
It includes technology from Sony's Bravia TV division called "Triluminos", which enhances its overall colour saturation, colour accuracy and contrast, and as a result makes photos and videos look really good on the 4.3in screen.
The woman's blue eyes are rendered with naturalistic accuracy, in contrast to the unfathomable stare that characterizes Modigliani's late works.

Simulation results reveal superior decomposition accuracy in contrast with coefficient domain algorithms due to relaxation of paraunitarity.
