图3. 不同大小的权重参数λ情况下训练的UNet-TVp网络重建得到的$R_{2}^{*}$参数图像. $R_{2}^{*}$参数图像的NRMSE值标于图像的右下角. 图片右边色条颜色由蓝到红代表着$R_{2}^{*}$值从小到大的变化（GT：真实参数图像）
Fig. 3. $R_{2}^{*}$ maps reconstructed by UNet-TVp with different λ values. The NRMSE values of $R_{2}^{*}$ maps are shown in the bottom right corner of the maps. The change of color in the color bar on the right side of the figure from blue to red represents the $R_{2}^{*}$ value from small to large (GT: ground truth)
