%X Conventional image reconstruction of cone-beam CT usually assumes a cube or its inscribed cylinder as the reconstruction region,considering the characteristic of large difference of reconstruction objects of industrial CT in size,a fast image reconstruction method based on minimal cylindrical reconstruction region was proposed.Firstly,the envelope diagram of minimal region of reconstruction object was obtained by line scan conversion algorithm from cone-beam projection data of different view.Then,the envelo...
