[An Easy-to-use Method for CT Image Simulation with Parameter Optimization Using a Water Phantom].

Purpose: We developed an easy-to-use method to generate computed tomography (CT) images that simulate the images obtained when using an actual scanner.

Methods: The developed method generates images by simulating the data acquisition and image reconstruction processes of a scanner from a linear attenuation coefficient map of an object numerically generated. This approach is similar to general image simulation methods.
