Methods and systems are provided for contrast-to-noise evaluation in medical imaging systems. In one embodiment, a method includes positioning a phantom having a variable width cross-section within a gantry of a computed tomography (CT) system so that the variable width cross-section is perpendicular to a central axis of the CT system, adjusting the phantom within the gantry of the CT system to a first imaging configuration having a first position and a first translation within the gantry, acquiring a first set of measurements from the phantom in the first imaging configuration, and calculating a contrast-to-noise ratio (CNR) of the CT system based on at least the first set of measurements and a first material density of an imaged slice of the phantom in the first imaging configuration.
