Compensating for B(1) inhomogeneity using active transmit power modulation.
The effect of poor B(1) homogeneity on MRI images not only affects the appearance of the images, but produces difficulty in automated segmentation and in certain quantification methods. While improved RF coil design is the first line in reducing such artifact, compensation methods can significantly...
