Voxel transform into axes

Hi I have a 3D voxel matrix which is fat of a breast tissue. Matrix size is (331,210,266). I know how to plot voxel data, but I want to give dielectric values of the fat to representing ones in the voxel matrix and I want to plot it with the axes values x,y,z. I dont know how to do it. Voxel size is 0.4297mm x 0.4297mm x 0.4297mm.

Any help appreciated. Thanks for your concern.
