An apparatus () for erasing a storage phosphor layer () includes a drive () for producing a relative movement between the storage phosphor layer () and the radiation source (), the storage phosphor layer () lying or being moved in a holding plane (), and a reflector () for reflecting radiation. The reflector () is arranged and designed to reflect erasing radiation reflected by the storage phosphor layer () in the direction of the storage phosphor layer (). A width () of the reflector () in the direction () of the relative movement is at least ten times as great as a smallest distance () between the reflector () and the holding plane ().

Storage phosphor layer and system and method for erasing same

An apparatus () for reading out X-ray information of an X-ray image stored in a storage phosphor layer () is pivotable and includes acquiring unit () for acquiring an orientation of the apparatus (). 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 ().

Apparatus for reading out X-ray information stored in storage phosphor layer and radiography module

An apparatus () for erasing a storage phosphor layer () with a holding plane () in which the storage phosphor layer () lies or can be moved, a radiation source () for irradiating the storage phosphor layer () with erasing radiation which is suitable for erasing the storage phosphor layer (), and a reflector () for reflecting erasing radiation in the direction of the holding plane (). In order to increase the erasing efficiency, provision is made such that the reflector () is arranged and/or designed such that it reflects erasing radiation, which is reflected by the storage phosphor layer (), in the direction of the storage phosphor layer (), and the radiation source () is disposed on a base (), the base () being disposed closer to the holding plane () than at least part of the reflector ().

An apparatus () for erasing a storage phosphor layer () includes a radiation source () for producing and emitting erasing radiation, a drive () for producing a relative movement between the storage phosphor layer () and the radiation source (), the storage phosphor layer () lying or being moved in a holding plane (), and a reflector () for reflecting radiation. The reflector () is arranged and designed to reflect erasing radiation reflected by the storage phosphor layer () in the direction of the storage phosphor layer (). A further reflecting surface () is provided for reflecting erasing radiation which is positioned opposite the reflector (), as considered in a direction at right angles to the direction () of the relative movement.

An apparatus () for reading out X-ray information of an X-ray image stored in a storage phosphor layer () includes an irradiation device () for irradiating the storage phosphor layer () with stimulation radiation () and a detection device () for collecting emission radiation () which the storage phosphor layer () emits as a result of the irradiation by means of the stimulation radiation (). The irradiation device () and the detection device () are fixedly or rigidly associated with one another. Furthermore, an actuation device () is provided for producing a relative movement between the storage phosphor layer () on the one hand and the irradiation device () and the detection device () on the other hand. According to the invention, the apparatus () includes acquiring unit () 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 ().
