An apparatus for reading out storage phosphor plates () for storing X-ray information with one or more rotating conveyance rolls (to) for conveying the storage phosphor plate (), an alignment edge () to which the storage phosphor plate () can be aligned, and a read-out device for reading out the X-ray information stored in the storage phosphor plate (). For more reliable alignment of the storage phosphor plate (), in particular also with a storage phosphor plate () orientated substantially horizontally, provision is made such that the storage phosphor plate () is conveyed by the rotating conveyance rolls () in direction (R, R') towards the alignment edge () and a control device is provided for setting a pressure with which the conveyance rolls () press onto the storage phosphor plate (), the pressure being set such that a slack or slippage occurs between the rotating conveyance rolls () and the storage phosphor plate () being conveyed when the storage phosphor plate () comes into contact with the alignment edge (), by means of which the storage phosphor plate () can change its orientation and thus be aligned to the alignment edge ().

Apparatus and method for reading out storage phosphor plates

A cassette () for a storage phosphor plate () comprises a cassette housing () with an opening () and a support () disposed movably within the cassette housing (), wherein the storage phosphor plate () lies on the support (). In order to simplify the structure of the cassette () and of the corresponding removal mechanism, provision is made such that the support () can be moved, together with the storage phosphor plate () lying on top of it, through the opening () of the cassette housing (), at least partially from the inside of the cassette housing (), and the storage phosphor plate () lying on the support () can be taken from the support () when the support () is located, with the storage phosphor plate () lying on top of it, at least partially outside of the cassette housing ().

Cassette for storage phosphor plate and apparatus for removing storage phosphor plate from cassette

An apparatus and a corresponding method for reading out a storage phosphor plate () with an insertion device for inserting a cassette () in which a movably disposed support () is located, on top of which the storage phosphor plate () lies, a read-out device () for reading out the storage phosphor plate () and a conveyance device () which takes the storage phosphor plate () from the support () and conveys it in a first direction (R) to the read-out device (). In order to achieve the most precise and reliable alignment possible of the storage phosphor plate () relative to the read-out device () in a simple way, a positioning device () is provided for shifting the support (), on which the storage phosphor plate () lies, in a second direction (A) which is different from the first direction (R) so that the support () and the storage phosphor plate () are aligned relative to the read-out device ().

An arrangement for unloading and loading of x-ray sheet film cassettes of standardized but different sizes of their flat sides which also can be used for receiving different sheet film sorts and reloadable with respective sheet film sorts, comprises a light-tight closeable shaft for receiving a cassette, transporting unit for inserting and withdrawing of the cassettes, unit for positioning the cassette at a cassette corner which is the same for all cassettes, a mechanically-electronic comparison device for determining the format of a cassette, an opening device for the cassette, unit for withdrawing a film and inserting of a new film into the cassette, and unit for automatically distinguishing of cassette types with the same sizes or size regions and loadable with different film sorts and including at least one outwardly sensible marking provided on the cassettes of at least one type, at least one sensor arranged to sense the marking with a positioned cassette, and a comparison device which is connected for the sensor for automatic selection of a sheet film size or sort for further loading.

An arrangement for determining two or more superimposed film sheets, particularly X-ray film sheets, in a transport after their withdrawal from the film sheet stack, has a light barrier with a light source at one side of the transport path and a photoreceiver at the other side thereof, and an evaluating circuit connected with the photoreceiver for producing a signal corresponding to the presence of two or more sheets and including a computer supplied with a value of the density of a first or test sheet introduced into the light barrier between the light source and the photoreceiver, so that the supplied value serves as a reference signal for measuring the next film sheet.
