发明名称 Method and apparatus for producing a three-dimensional computerized tomography image of an object with improved conversion of cone beam data to radon data
摘要 Cone beam geometry imaging uses an area or two-dimensional array detector and a cone beam x-ray source. Image reconstruction by inverse Radon transformation is used following the calculation of planar integrals. Specifically, the integral is calculated by first changing it to a form wherein fast Fourier transforms can be used to minimize the number of operations in the calculations of the integral.
