HelloSlicer community,  
i have a problem with suv calculation which seems not wrong between a vendor one and slicer.  
Operating system:Window  
Slicer version: 4.10.2  
Expected behavior:The suvbw calculation do no correspond to ISP philips or hand calculation by more than 10%. The SUV should be around 1. I measure around 0.98 with ISP and 0.87 with 3d slicer  
Actual behavior:  
Here a link to the image.
