  • Abstract
    Synthetic CT noise emulation in the raw data domain is reported. A method that synthetically adds noise directly in the raw data domain (i.e., before the negative log and associated pre processing) is presented. Initial results are obtained for a noise simulation method that lowers the effective tube current for a CT data set while considering quantum noise, electronic noise, bowtie filtration, and kVp. Focus is on simulation results where the control is more on the parameters generating many realizations.
