Abstract
A method for converting spectral CT datasets into electron density datasets with applications in the fields of medical image formation or radiation treatment planning. The method comprises a preparation method that fits free parameters of a generalized electron density prediction model based on obtained electron density values such as data on tissue substitutes, and a conversion method using the fitted parameter prediction model and spectrally decomposed CT data as first and second inputs, respectively. The method is particularly useful in dual-energy CT and more specifically in dual layer detector CT systems.
