Does the " intensity range" mean the "Hounsfield unit" on CT dicom image?

I am trying the segmentation editor by intensity range on my CT dicom image.
Does the " intensity range" mean the “Hounsfield unit” on CT dicom image???
I compare the same dicom image on the 3D slicer and other dicom viewer. It seems the " intensity range" on 3D slicer equal to Hounsfield unit. But I am not sure about this point.

Operating system: Windows 10
Slicer version: 4.11.0
Expected behavior: segmentation by intensity range
Actual behavior:

Hi ,while searching for the House Field unit, I have a question here.

@lassoan

Yes, voxel values of a CT volume is in HU.

According to this comment, is it correct to indicate the segmented HA value in the segment editor in the picture?

[lassoan (Andras Lasso)]

Yes, in clinical CT images, voxel values are in HU and the threshold range is defined in HU.
