Create a voxel element per pixel in a segmentation/model

I would like to generate a voxel element that is the size of each pixel (voxel in 3D) and get the densities of each element.
However, I am not quite sure how to do that in SegmentMesher. I played around with the settings for it and I am unable to get the desired voxels nor the mapping per pixel.

Is there a method to do this?
