Trying to understand the different coordinate systems

I am trying to make a bounding box based on a segmentation. I initially tried using SimpleITK and their LabelShapeStatisticsImageFilter class and their GetBoundingBox method to get some coordinates. When I tried doing the same thing in Slicer, the coordinates of the bounding box appears to be different. I understand their might be a difference in the coordinate system but I’m not fully understanding it even after reading the documentation. I just want to confirm that both outputs are essentially the same. Is there are a formula I should use to convert the outputs from the SimpleITK method to match the outputs of the Slicer method? Thank you again .
