Figure 1
Example of the ROI selection for image quality analysis. (a) 2D slice where the red rectangle represents the soft tissue ROI, the yellow rectangle represents the air ROI, and the green rectangle on the soft tissue–air interface is used to perform the line profile extraction. The magnified inset shows the ROI of the interface, and the red lines are the line profiles considered. (b) Line profile extracted from the soft tissue–air interface. The blue lines represent the highest and lowest values, soft tissue and air, respectively, while the red profile is the average of all the line profiles considered, and the light blue lines are the error bars. (c) The scatter plot depicts the first derivative of the line profile, and the orange line shows the Gaussian fit.
