专利汇可以提供Three-dimensional reprojector专利检索,专利查询,专利分析的服务。并且PURPOSE:To obtain a three-dimensional reprojected picture at high speed by the use of a two-dimensional picture processing means by rotating respective stored tomographic images in a reprojecting direction, obtaining the peripheral distribution of a variable density in the respective rotated tomographic images and outputting as the line data of the reprojected picture. CONSTITUTION:The successive tomographic images successively formed in a tomographic image forming device 1 are sequentially stored in a two-dimensional picture memory 2, thereafter, the respective tomographic images of the two dimensional picture memory 2 are read by a two-dimensional affine transformation means 3 and rotated in the reprojecting direction. The integrating distribution of the variable density values in the x, y directions of the respective tomographic images rotated in the reprojecting direction is obtained by the use of a two-dimensional peripheral distribution measuring means 4, thereafter, the peripheral distribution data is outputted as the line data of the reprojected picture. Thereby, the three-dimensional reprojected picture can be obtained at high speed by the use of the two-dimensional picture processing means.,下面是Three-dimensional reprojector专利的具体信息内容。
