Figure 4From: Assessing tumor contrast in radiographically dense breast tissue using Diffuse Optical Spectroscopic Imaging (DOSI)Box plot of the TOI and STC index in tumor, areola and normal tissue. (A) TOI values in the visible tumor, areola and normal tissue of the ipsilateral breast. (B) STC index values in the visible tumor, areola and normal tissue of the ipsilateral breast. STC, Specific tumor component; TOI, Tissue optical index.Back to article page
