(B) NIR image was captured without pressure and with the target placed at the location indicated by the black hollow circle at 12 o’clock. (C) Post-processed NIR image after co-registering, subtracting, and masking. The black hollow circle in (B and C) depicts the 2D location of the target at 12 o’clock position in the intramammary fold of the left breast.
