Title: Positron ct apparatus
Inventor: NARITA YUICHIRO
IPC: G01T1/161
Filed: 2000-03-29
Abstract: PROBLEM TO BE SOLVED: To perform relatively accurate scattered radiation correction in a short time by reducing complex computation processes. SOLUTION: Projection data in a discrete value distribution on a plane of projection having a body axis direction and a slice in-plane direction are produced from measured emission data, and scattering medium distribution on the same plane of projection is found from a three-dimensional TCT image reconstituted from measured transmission data. Scattered radiation distribution on the plane of projection is calculated from these results. Scattering angles, scattering energy, and scattered radiation loci are calculated from the three- dimensional TCT image to calculate the adsorption efficiency of scattered radiation.  The results of the calculation of the adsorption efficiency are subtracted from the scattered radiation distribution, and then the resultant results are subtracted from the projection data to rearrange the resultant projection data into a sinogram, which is used for the calculation for reconstituting the three-dimensional ECT image.
