    【Abstract】 AIM: To study the image enhancement principle of Pal fuzzy algorithms and to propose a fast fuzzy enhancement algorithm fitting for CT/MR image. METHODS: The region of interest (ROI) was separated from the region of background by a novel linear mapping function and further enhanced by the linear general fuzzy operator. RESULTS: Fifty CT/MR images were implemented in IDL on a PC with Intel Pentium 4 2.4 GHz, 512 M RAM and 128 M RAMDAC, which revealed that it took about 0.8 ms to enhance each image using the algorithm proposed. CONCLUSION: The algorithm presented by this paper reduces the computation load and speeds up the process. ......
