Figure 7
Differential tissue blood oxygen saturation and total hemoglobin concentration measurements for benign and malignant tumors. Plot based on the dataset shown in Figures 4 and 5. x axis, differential tissue blood oxygen saturation ([StO2]) determined by subtracting the [StO2] measurement of the suspicious breast lesion (tumor) from that of the normal surrounding breast parenchyma (reference); y axis, differential total hemoglobin concentration ([Hbt]) determined by subtracting the [Hbt] measurement of the suspicious breast lesion (tumor) from that of the normal surrounding breast parenchyma (reference).
