Patent number: 4219876Abstract: In a computed tomography system using radiation, a large number of radiation beams are projected into a selected slice-like sectional portion of a subject to be reconstructed, in various directions. A profile of measured projection data is obtained from the radiation beams penetrated in parallel at each given angular interval. The profile of measured projection data thus obtained is subjected to a filtering operation to produce profiles of first modified projection data. The profile of modified projection data is recasted at properly selected intervals to produce second modified projection data. This results in a remarkable reduction of the amount of weight coefficients required in an interpolation to calculate the modified projection data for a large number of picture elements defined in matrix fashion on the sectional portion.Type: GrantFiled: June 14, 1978Date of Patent: August 26, 1980Assignee: Tokyo Shibaura Electric Co., Ltd.Inventors: Hiroyuki Mizutani, Toshio Uehara
