Correction to: EJNMMI Physics 9, 52 (2022) https://doi.org/10.1186/s40658-022-00481-z
Following publication of the original article [1], an error in Fig. 1 was reported by the authors. In the top blue box, the intensity of the 87.1 keV X-ray was quoted as 1.2%, but it should be 2.0%. The updated figure is provided in this correction article.
The authors would also like to specify that a scatter filter of 12 mm was used for all the SPECT images analysed. The ‘no filter’ results refer to images where no post-filter was applied.
The original article [1] has been updated.
Decay scheme of 212Pb. The mean alpha and beta energies are included. The relevant photons emitted and their energies are added to the transition. Photons with emission probabilities smaller than 1% per 212Pb decay or with energies below 70 keV are not included. The data are taken from ICRP 107 [2]
