Table 4 Absorbed dose to water measured and calculated by MCNP4c and Raydose MC codes. \( {\overline{\mathrm{D}}}_{\mathrm{w}}^{\mathrm{meas}} \) and \( {\mathrm{D}}_{\mathrm{w}}^{\mathrm{MCNP}} \) are in the ratio 1.08, while \( {\overline{\mathrm{D}}}_{\mathrm{w}}^{\mathrm{meas}} \) and \( {\mathrm{D}}_{\mathrm{w}}^{\mathrm{Raydose}} \) are in the ratio 1.03, well within the stated uncertainties. \( {\overline{\mathrm{D}}}_{\mathrm{w}}^{\mathrm{meas}} \): absorbed dose per emitted beta particle measured using LiF:Mg,Cu,P TLDs. \( {\mathrm{D}}_{\mathrm{w}}^{\mathrm{MCNP}} \): absorbed dose per emitted beta particle calculated using MCNP4c in analytical geometry. \( {D}_w^{Raydose} \): absorbed dose per emitted beta particle calculated running Raydose on 90Y–PET images

From: Phantom validation of quantitative Y-90 PET/CT-based dosimetry in liver radioembolization
