Hi 3D slicer experts:  
I imported Dicom RT DOSE data into 3Dslicer to compare dose distributions using Dose comparison.  
I want to know the meaning of the numbers displayed in DataProbe. It seemed to differ from the actual dose value.  
thanks.

I don’t know anything about dose data, but the number that you boxed in is the value of the voxel under your mouse cursor.

thanks.  
I solved.  
By importing the Dicom RT Dose and Dicom RT Plan, it displayed the dose value.
