What is the minimum unit of pixel value in CT

The smallest unit of the fountain pen in segmentation is the smallest pixel of CT, but the distribution of brightness and darkness can be seen within a single pixel. How is the intensity value within a single pixel determined

When the CT image is displayed, the continuous signal is reconstructed from the discrete samples. That’s why you always see a continuous gray level changes, regardless of how much you zoom in.

You can find voxel spacing of the image in Volumes module / Volume information section. You can find voxel spacing of the segmentation if you click the “Segment Geometry” button in Segment Editor.
