Figure 7From: Tool to visualize and evaluate operator proficiency in laser hair-removal treatments Synthetic LDM to illustrate the computation process of performance indices. The LDM has three overlapped laser spots and the pixel values indicate the amount of laser exposure at the site. Here, the maximum redundancy in laser delivery is 3 and the centroid position of each laser spot was marked as red. The indices δ0 and δz are computed based on the pixel values, and μ and υ are computed based on the centroid position of laser spots.Back to article page
