Thanks for your response!!  
“If you can give reference to a paper then I’ll update the example script accordingly.”

sure.Here are the links of the papers.  
[Paper1](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4091626/)  
[Paper2](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3075464/)  
According to these papers"To qualify as a calcified plaque using CAC scoring, the plaque calcium density, measured in Hounsfield units, must be 130 Hu or higher."

"What do you mean by “3 consecutive voxels”?

According to paper2 “Agatston score, requiring 3 contiguous voxels of \>=130 Hounsfield units to be classified as calcified plaque”.Means…for example if we have one CT slice with a calcified spot occupying 4 consecutive pixels,if just 2 out of that 5 pixels are \>=130 HU than we cant classify it as calcified plaque/agatston score.

“Would you be interested in converting the example script to a Slicer module?”  
No.I just want to understand how the algorithm is working.And if I apply this algorithm to calculate calcium score of my dataset than is it calculating the score according to the principles/my conditions.So basically I want to modify it based on the informaion i have mentioned above(\>=130HU and 3 consecutive pixels).
