In-room imaging and MR planning

Same principles and derivation employed for pseudo-monoenergetic images. Once the contribution of each basis material are calculated for one voxel, a weighted average of their electron densities (instead of the attenuation values) is performed. Electron Density and Effective Atomic Number Images Material Basis Method (more robust)

Pseudo-monoenergetic formula

Electron density formula (does not depend on energy)
