ABSTRACT:
An apparatus (1) for reading out X-ray information of an X-ray image stored in a storage phosphor layer (4) includes an irradiation device (13) for irradiating the storage phosphor layer (4) with stimulation radiation (14) and a detection device (16) for collecting emission radiation (15) which the storage phosphor layer (4) emits as a result of the irradiation by means of the stimulation radiation (14). The irradiation device (13) and the detection device (16) are fixedly or rigidly associated with one another. Furthermore, an actuation device (8) is provided for producing a relative movement between the storage phosphor layer (4) on the one hand and the irradiation device (13) and the detection device (16) on the other hand. According to the invention, the apparatus (1) includes acquiring unit (19, 19′, 20, 20′, 21, 21′) for acquiring a speed of the relative movement. In this way, in a technically simple way, good image quality of an X-ray image read out can be guaranteed. Furthermore, the invention relates to a radiography module with this type of apparatus (1).
