[J. Biophotonics 9, No. 11–12, 1344–1354 (2016)]
In the article by R. Penjweini, M.M. Kim, et al. (doi: 10.1002/jbio.201600121), published in J. Biophotonics 9, 1344–1354 (2016), the constants C01, C02, b1, and b2 determined from fitting the fluorescence single value decomposition (SVD) for phantoms with different optical properties and the corresponding Figure 2(a) are not correct. This erratum is published to correct the section 2.3 and Figure 2(a).
The “Measurements of the HPPH concentration prior to and post PDT” in section 2.3 and Figure 2(a) should read:
The attenuation of HPPH fluorescence signal due to the light absorption and scattering by tissue was corrected by applying an empirical correction factor (CF) of the following form [16, 18, 31]:
where C01, C02, b1, and b2 are constants (0.469, 0.0543, 0.657, and −0.0193 respectively) determined from fitting the fluorescence SVD for phantoms with different optical absorption coefficients, μa and optical reduced scattering coefficients, μs’. The correction factor is specific to the probe and semi-infinite geometry setup used for the measurements.
