摘要：
A simple method to denoise ratio images in magnetic resonance imaging, includes generating a MRI sequence provided for acquiring data from an object to be imaged, wherein the MRI sequence is configured for generating at least two different standard images, respectively a first standard image and a second standard image, acquiring the two different standard images, and combining the two different standard images in a ratio image. The ratio image is obtained by calculating a ratio of the first standard image and the second standard image that is tunable by a parameter γ wherein the parameter γ is automatically chosen for maximizing the negentropy of the ratio image.
