For AP projections of the chest using a portable x-ray unit, placing the IR lengthwise can create distortion and magnification in hypersthenic and asthenic body habitus due to their extremes in body shape. For hypersthenics, it is recommended to place the IR in a landscape position (crosswise) to reduce magnification, and for asthenics, it is recommended to place the IR in a portrait position (lengthwise) to prevent distortion. For hyposthenic and sthenic body habitus, either position of the IR can be used with good image quality.
