    摘要: The invention relates to a device (10,60) for reading out information stored in a phosphor carrier (15) and to an X-ray cassette (70) which contains the phosphor carrier (15) and such a device. The inventive device (10,60) has a radiation source (11;20, . . . ,29,30 . . . 39; 50,53;61) that can emit a first radiation source (16) with which the phosphor carrier (15) can be exited such that the carrier emits a second radiation (17). This second radiation (17) comprises an image of the information stored in the phosphor carrier (15). The device (10,60) additionally has a receiving means (12,62) which contains a number of point elements (PD1, . . . PDn) in order to receive the second radiation (17) emitted from the phosphor carrier (15) in a point-by-point manner. The second radiation of a point of the phosphor carrier (15) can thus be received by each one of the point elements (PD1, . . . ,PDn).

    摘要: A device (1) and a method for reading information stored in a phosphor layer (10) is disclosed. The device (1) includes a transparent carrier material (9) on which the phosphor layer (10) to be read is disposed. A radiation source (2) emits an excitation radiation (20) to excite the phosphor layer (10), which in turn emits an emission radiation (26). The emission radiation (26) can be received by a receiver (3). The radiation source (2) is arranged on one side of the transparent carrier material (9), whereas the receiver (3) is arranged on the other side of the transparent carrier material (9), thereby defining an optical path between the radiation source (2) and the receiver (3). According to the invention, a reflective layer (21, 22; 30, 31, 32) for reflecting at least a portion of the excitation radiation (20) is arranged in the optical path.

    摘要: The present invention reduces the influences of electromagnetic fields during reading out of image signals from memory phosphor films. This is done by pre-amplifying the detection signals obtained from a detection device, in particular a CCD array, before further processing, for example by an analog-to-digital converter. An amplification register for electron multiplying can be used for the amplification. In this way individual photon sensitivity can be achieved when reading out X-ray images.
