Abstract
A magnetic resonance imaging (MRI) system, process, display processing system and/or computer readable medium with stored program code structure thereon is configured to provide for obtaining a composite image which simultaneously includes information from a magnitude MR image and a phase MR image. The composite image is generated by assigning a first color display channel to the magnitude MR image and a second color display channel to the phase MR image, and generating the composite image by assigning to respective pixels in the composite image color values based upon a combination of corresponding pixels in the assigned first and second color display channels.
