Purpose: To propose a transition region extraction algorithm for two point fat-water separation.

Methods:In the proposed method, fat-water transition region is first extracted as initial information. Remaining pixels are determined based on transition region in units of sub-region instead of pixels to improve calculation efficiency and avoid the vulnerability to the growing path.

Results:Fat-water separation were successfully achieved by the proposed method in the datasets tested.

Conclusion: A method based on fat-water transition region extraction is proposed for two point fat-water separation.
