Monte Carlo scatter correction method for computed tomography of general object geometries |
摘要 |
A method of correcting aberrations caused by target x-ray scatter in three-dimensional images generated by a volumetric computed tomographic system is disclosed. The method uses a Monte Carlo simulation to determine the distribution of scattered radiation reaching the detector plane. The geometry for the scatter calculation is determined using the uncorrected three-dimensional tomographic image. The calculated scatter is used to correct the primary projection data which is then processed routinely to provide the corrected image.
