Abstract

A method of generating a preview of at least one low-dose x-ray image includes the followings steps: obtaining an initial volumetric representation of a patient from an x-ray device; creating at least one x-ray image projection from the initial volumetric representation; injecting correlated noise into at least one of the x-ray image projections; and processing the noise-injected x-ray image projections to create at least one preview of a patient-specific low-dose x-ray for showing to a user. There are also described a device for generating at least one preview of a low-dose x-ray image, a corresponding imaging system, and a non-transitory computer readable medium.
