From: Simplified dosimetry for kidneys and tumors in 177Lu-labeled peptide receptor radionuclide therapy
Absorbed doses to the tumors normalized against “true” absorbed doses. Absorbed doses were calculated using the 1 d images and \(T_{{{\text{eff}}}}\) from the first treatment cycle (a), using the 7 d images and \(T_{{{\text{eff}}}}\) from the first cycle (b), using the 1 d images and a fixed \(T_{{{\text{eff}}}}\) (c), and using the 7 d images and a fixed \(T_{{{\text{eff}}}}\) (d). “All” refers to the total absorbed dose from all treatment cycles, n corresponds to number of data points included in the calculation for the corresponding treatment cycle
