Qiu, Kim, Penjweini, and Zhu: Erratum: Macroscopic singlet oxygen modeling for dosimetry of Photofrin-mediated photodynamic therapy: an in-vivo study

This article [J. Biomed. Opt. 21(8), 088002 (2016)] was originally published online on 23 August 2016 with an error in Figure 2 and the constants C01, C02, b1, and b2 in Eq. (2). This erratum is published to correct Sec. 2.5 and Fig. 2(a).

Section 2.5 “Measurement of the Photofrin Concentration in Tumors” should read:

The attenuation of Photofrin fluorescence signal due to the light absorption and scattering by tissue was corrected by applying an empirical correction factor (CF)

(2)

CF=C01+C02μsμs·exp[(b1+b2μs)·3μaμs],
where constants C01=0.30±0.11, C02=0.035±0.019, b1=0.78±0.11, and b2=0.026±0.014 were determined from fitting the fluorescence SVD for phantoms with different μa and μs. The correction factor is specific to the probe and the semi-infinite geometry set-up used for the measurements.
