激光CT 激光CT的基本原理与X线CT的相同点是向生物体内多方向照射光束,并探测通过生物体的光,然后用计算机处理使之图象化。与X射线CT不同之处是,用激光而不是X射线。 日本日立制作所与东海大学医学部共同开发的高分辨的光CT已成功的实现了老鼠脑内氧浓度分布图象化。采用的激光源是适合于计测物体内氧浓度的770nm The basic principle of laser CT laser CT and X-ray CT is the same point to the body of radiation in multiple directions, and detect the light through the body, and then use computer processing to visualize. Unlike X-ray CT, laser light is used instead of X-rays. High-resolution optical CT developed by Japan’s Hitachi Laboratory and Tokai University Medical Department has succeeded in visualization of oxygen concentration distribution in the brain of mice. The laser source used is 770nm suitable for measuring the oxygen concentration in the object
