Air length equivalent in the y-z plane for different x values


 

 

Unlike gammagraphy, a single scan provides a measure of  the amount of air along each gamma ray path.

 

In the case shown here it has been assumed that the amount of air along each gamma ray path is uniformly distributed around the center of the block.
