Theoretically, an XCT reconstruction from attenuation data is a map of the linear attenuation of the materials in the phantom. i.e. If you scan a copper sphere, then the reconstruction should look like a sphere with the value zero outside the sphere and inside the sphere the value should be the attenuation coefficient of copper.
Even though we have made the transition to real world units, reconstructions of data collected with xdesign are not scaled correctly. e.g. reconstruction returns a map with incorrect values.
