1 Date of download: 7/1/2016 Copyright © 2016 SPIE. All rights reserved. Summary of MFI image types. (a) Plot of 18 image types collected by system. Six reflectance images are represented by asterisks having equal excitation and emission wavelengths. Twelve fluorescence images are represented by boxes with height representing 20-nm FHWM illumination bandwidth and width representing the bandwidth of the collected emission. (b) The absorption spectrum of hemoglobin from 250 to 650 nm (data 41 ). Vertical dotted lines correspond to six recorded reflectance images from the MFI system. HbO2, oxygenated hemoglobin and Hb, deoxygenated hemoglobin. Figure Legend: From: Multispectral fluorescence imaging of human ovarian and fallopian tube tissue for early-stage cancer detection J.

Within each image, the two tissue samples on the left are histologically normal fallopian tube samples and the two samples on the right are histologically normal ovary samples. Image gray scale values have been compressed to 8 bits for display, and contrast window and level have been adjusted between rows to account for significant differences in image intensity. Thus, the intensities within a row of images are comparable, but the intensities between rows are not.

3 Date of download: 7/1/2016 Copyright © 2016 SPIE. All rights reserved. Representative images of ovarian tissue. Within each column, the top three tissues are cancer samples, the middle three are normal samples and the bottom three are benign samples. The three samples for each pathology are representative of the range of intensities measured for the given pathology. From left to right, the columns are image type F320blue, F370, R400, R415, and R480. The QDA model using these five image types had zero resubstitution errors. The images are saved as floating point TIFF files for statistical comparison. The significant differences in intensities and dynamic range between image types require the images to be log scaled for visualization with the same window and level settings.

Figure Legend: From: Multispectral fluorescence imaging of human ovarian and fallopian tube tissue for early-stage cancer detection J. Biomed. Opt. 2016;21(5):056005. doi:10.1117/1.JBO.21.5.056005

5 Date of download: 7/1/2016 Copyright © 2016 SPIE. All rights reserved. ROC curves for ovarian tissue MLR models. Dotted diagonal lines represent a model with no predictive power (AUC of 0.5). (a) Fluorescence model using image types F440 and F480 with AUC of 0.9036 and (b) reflectance model using image types R440 and R480 with AUC of 0.946. Figure Legend: From: Multispectral fluorescence imaging of human ovarian and fallopian tube tissue for early-stage cancer detection J. Biomed. Opt. 2016;21(5):056005. doi:10.1117/1.JBO.21.5.056005

6 Date of download: 7/1/2016 Copyright © 2016 SPIE. All rights reserved. Mean (a) ovarian and (b) fallopian tube tissue intensity and standard error for each pathological group normalized to the normal group mean intensity for each image type. Standard error bars for ovarian tissue are robust standard error. Error bars are not shown for cancerous fallopian tube due to a sample size of one.
