The imaging technologies of fluorescence currently are developed in biological medicine included broad-field fluorescence imaging, point-probe fluorescence imaging, and cross-sectional endoluminal fluorescence imaging respectively. This periodicalĄ¯s editor introduced broad-field fluorescence imagingĄ¯s latest developments in technology in this issue, and illustrated a photo retouching system for decreasing the fluorescence signal-to-noise ratio in photodynamic therapy (PDT) for skin cancer. The animal test also verified that this camera-based instrument still could capture the red fluorescence under a low-dosed light sensitive drug and the scope of distribution of melanoma cells in the vein could clearly be observed. %K Broad-Field Fluorescence Imaging %K Photo Retouching %K Signal-To-Noise %K Photodynamic Therapy (PDT) %U http://article.sapub.org/10.5923.j.instrument.20120102.02.html
