A Projection Method for Three-dimensional CT at Arbitrary Incident Angle

WANG Zhao ba (Research Center for NDT, North China Institute of Technology, Taiyuan 030051, China)  
A non conventional projection method for three dimensional CT is described in which the angle between the main X ray beam and the rotation axis of object is arbitrary. Three dimensional CT for the industrial pieces with large and flat size can be carried out by means of this method with a low energy X ray source. The back projection algorithm reconstructing a 3D object for above projection method is derived and verified through simulation .
