Moreover, the evaluation of NUC algorithms is not straightforward because the true amount of non-uniformity in MRI images is unknown, and it is therefore not possible to directly measure the accuracy of the non-uniformity correction. Comparisons of NUC methods have been reported using simulated ...
While the N4 generally performs well in the case of simple tissue structures, a strong intensity correction can occur when the tissue structures are more complex. Therefore, we propose a novel fully automated approach for the correction of intensity non-uniformity for retrospective evaluation of MR ...

This uniformity is crucial in avoiding thermal gradients, which can result in thermal stresses, possibly leading to cracking. Research indicates that a faster heating rate can diminish the endurance against elevated temperatures of ultra-high-performance concrete columns [85]. This heating rate can ...
Distributed phase plates (DPP), which are also known as random phase masks (RPM), have been used in laser fusion systems in order to improve the uniformity of intensity of laser beams which illuminate laser fusion targets so as to reduce near-field phase and intensity errors which produce hot...
