图7 利用模拟DWI数据对四种算法在4%噪声水平和不同b值下的去噪图像和无噪图像、噪声图像的视觉比较.数字是对应的以dB为单位的PSNR，b值单位为s/mm2

Fig. 7 Visual comparison of the denoised images, noise-free images, and noise images of the four algorithms using the simulated DWI data with 4% noise level and different b-values. The numbers reported are PSNR values in dB, and the b-values are in s/mm2
