Fig. 8
Scatter plots of the average score for different subjective metrics for the images of the 120 patients in the evaluation set, with the anatomical conspicuity (AC) metric in the left column, the lesion conspicuity (LC) metric in the middle column, and the image noise (IN) metric in the right column. The subcolumns from left to right are the average scores of two readers’ subjective ratings of the original images and the images processed by the NLM method, 3DNet and p3DNet, respectively. (There are a total of 120 points for each metric. The brightness of the region is proportional to the concentration of the points. The 600 s group achieved scores of 5 for all metrics)
