Of late years, Interventional Radiology[IVR]comes into wide use rapidly. However the examination and fluoroscopy times get long relatively as a result of diversification of examination contents at the IVR, and this causes a problem of an amount of patient radiation dose. This time, we studied to reduce the radiation dose by means of wave tail cutting of the tube voltage at pulse fluoroscopy of IVR. As a result, it enabled us to reduce the radiation dose by 16-20% using the high-voltage semiconductor switch to cut the wave tail. It is important to reduce radiation dose taking into account of tube voltage wave tail at pulse fluoroscopy of IVR.
