Hallo I encountered some obstacles, attached to the pictures  
It seems to me that the extension is in the process of development…because I noticed that there is a difference in the results, for example:

I downloaded the 3D slicing software using the CT Lung Analyzer on two laptops  
The first laptop gave me the COVID results as pictured 1111(image 1)  
The second laptop gave me the COVID results as pictured 2222 (image 2)  
Which of the results is correct?  
whts the best parameter’s … % affected lung as a severity parameter or collapse or infiltrated ???

please helpe me

Best regards
