A Support Vector Machine Classification of Thyroid Bioptic Specimens Using MALDI-MSI Data

Figure 4

Pixel-by-pixel classification. An entire thyroid cytological smear is displayed. A mass spectrum was acquired for each pixel and the pixel-by-pixel classification has been applied. Green pixels correspond to spectra classified as benign (HP: hyperplastic) while red pixels correspond to malignant (PTC: papillary thyroid carcinoma) spectra.
