A system for reading out X-ray information stored in a phosphor layer, includes: a read-out unit having components for irradiating the phosphor layer with stimulation radiation which can stimulate the phosphor layer to emit emission radiation dependent upon the X-ray information contained in the phosphor layer, and for collecting the emission radiation stimulated in the phosphor layer; and a carrier onto which the read-out unit is mounted. At least one of the components of the read-out unit is mounted onto the carrier over at least one first bearing which has a translatory degree of freedom in a first direction. The first bearing enables movement of the at least one component in relation to the carrier in the first direction.
