Abstract
Example embodiments relate to a water/fat image identification method and device including obtaining a water/fat image pair calculated by a Dixon method, and marking these as a first image and a second image; calculating grayscale histograms for the first image and the second image, respectively, to obtain a first grayscale histogram and second grayscale histogram; subtracting the second grayscale histogram from the first grayscale histogram to obtain a water/fat relationship graph; searching for the highest peak and lowest trough in the water/fat relationship graph, and if the highest peak is located behind the lowest trough, determining the first image as being a water image and the second image as being a fat image; and otherwise, determining the opposite.
