1. A magnetic resonance imaging method, comprising the following steps: generating a magnetic resonance imaging sequence provided for acquiring data from an object to be imaged, and configuring the magnetic resonance imaging sequence for generating at least two different respective standard images including a first standard image and a second standard image; acquiring the two different standard images; combining the two different standard images in a ratio image; and obtaining the ratio image by calculating a ratio of the first standard image and the second standard image being tunable by a parameter γ and automatically choosing the parameter γ for maximizing negentropy of the ratio image.
