Data acquisition for CT calibration

Why is it important :

Dose calculation algorithm will be commissioned comparing measurements with dose calculation in homogeneous and heterogeneous phantoms

The accuracy of dose calculation in patients will depend on the CT mapping to some physical descriptor that will be used in the calculation (electron density, mass density, composition)

Check the calibration curve for the range of clinically relevant densities and CT settings (kVp)
