To obtaine successful results in the therapeutic application of lasers, understanding laser beam distribution on lased tissue is essnetial. However there are few practically available techniques to observe the distribution of near-infrared lasers. The charge-coupled device (CCD) image sensors have an excellent sensitivity to near-infrared ranges, and so the authros have studied on imaging technique for near-infrared laser beam distribution in tissues using a TV camera with the CCD image sensor. As the result of this experiment, it has been confirmed that the near-infrared laser beam distribution on tissues was easily taken as a visible pattern by CCD camera on a CRT frame. Since the CCD camera can visualize the near-infrared laser beam distribution on tissues directly on the image of a subject, every part of the near-infrared laser beam distribution can be exactly corresponded to the subject. And so this technique is very useful for the clinical application of near-infrared lasers. The greatest advantage of this technique is the applicability to monitoring of the laser distribution on the tissue during the operation with near-infrared laser. The results of this experiment suggest possible application of this technique to "laser-intensitography".
