CT Slice Thickness Calculator
Plan CT reconstruction settings by estimating image count, overlap or gap, effective coverage, and optional helical pitch from table feed and collimation.

How the calculator works
Estimated images = scan coverage length / reconstruction interval. Overlap or gap = slice thickness - reconstruction interval. Pitch = table feed per rotation / total collimation. This is a planning helper, not a replacement for scanner protocol review.
