摘要:
In a method and apparatus for improving the brightness uniformity in an image, signals are acquired using a radio frequency receiving coil, and noise in the acquired signals is normalized so as to produce an image, then the brightness of various pixels in the image is determined according to the sensitivity of the radio frequency receiving coil. The brightness of the image is then made uniform by compensating the brightness of the various pixels in the image.
