Other parameterized phantoms: (a) latin square of different sizes, (b) random circles of varying levels of attenuation, (c) a unit circle, (d) lines of increasingly smaller width, (e) slanted squares, (f) Siemens star. Phantoms (a), (b), (e) could be used for studying the effects of reconstruction on objects of different sizes and attenuation. Phantom (c) could be used for noise reduction studies. Phantoms (d) and (f) could all be used to calculate the modulation transfer function (MTF).
