Method validation by in vivo NIR fluorescence imaging of mouse tail vessels. (A) The original fluorescence image of three blood vessels inside the mouse tail. The yellow frame is magnified to indicate the structure of the three vessels. (B) The processed image given by our method. The same area was magnified as in (A). (C) The white light color image of the mouse tail. The three blood vessels can be clearly seen as they are close to the skin surface. (D) The comparison of fluorescence intensity curves at the yellow line indicated in the right bottom of (C).
