Dose calculation issues ‚in practice‘: Hounsfield (CT-) value calibration

…a sometimes (!?) underrated issue!

• input for clinical dose calculation algorithms: local electron or mass densities in the patient • these are typically determined based on the Hounsfield (CT-) values via calibration curves → MIND potential errors in calibration curve, or Hounsfield stability problems of CT hardware
