Abstract

See full text

A method of computing statistical weights for a computed tomography (CT) iterative reconstruction process is provided. The method includes obtaining detector count data from a CT scan of an object; calculating variance data based on the count data and an electronic noise variance; transforming the calculated variance data to obtain statistical weight data; and performing the CT iterative reconstruction process using the statistical weight data and raw projection data to obtain a reconstructed CT image.
