Multiplex coherent anti-Stokes Raman scattering microspectroscopy of brain tissue with higher ranking data classification for biomedical imaging
in: Journal of Biomedical Optics (2017)
Multiplex Coherent Anti Stokes Raman Scattering (MCARS) microscopy was carried out to map a solid tumor in mouse brain tissue. The border between normal and tumor tissue was visualized using support vector machines (SVM) as a higher ranking type of data classification. Training data was collected separately in both tissue types, the image contrast is based on class affiliation of the single spectra. Color coding in the image generated by SVM is then related to pathological information instead of single spectral intensities or spectral differences within the data set. The results show good agreement with the HE stained reference and spontaneous Raman microscopy proving the validity of the MCARS-approach in combination with SVM.
