Abstract: 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.

Abstract: The invention relates to a method for reading out information stored in a phosphor layer whereby the phosphor layer is stimulated into emitting emission light by stimulation light produced from a light source, and the emission light emitted from one or several areas of the phosphor layer is collected by a detector moved relative to the phosphor layer, and then converted into corresponding emission light signals. In order to improve the signal/noise ratio, the light source is momentarily switched off at least once during the movement of the detector relative to the phosphor layer, when the light source is switched off. A background, which is caused by the ambient light and/or dark currents in the detector, is collected by the detector and converted into a corresponding background signal. The background signal is then used for correcting the emission light signals.

Abstract: An X-Ray cassette (1) and a device (10) for reading information stored in a memory layer (15) are disclosed. This device (10) contains a radiation source (11) to excite a row (34) of the memory layer (15). The row (34) emits an emission radiation (17) because of this excitation. The device (10) based on the invention contains a receptor (12) to receive the emission radiation (17). The receptor (12) includes a number of light-sensitive surfaces (18) that are arranged in adjacent rows. According to the invention, the dimension of the light-sensitive surfaces (18) of the receptor (12) arranged perpendicular to the orientation (A) of the rows (34) is greater than that oriented along the row direction (B). Alternatively or additionally, the device can include an optical projector (14) by means of which the emission radiation (17) is projected onto the receptor (12). The numerical aperture of the optical projector (14) with respect to the excited row (34) arranged perpendicular to the orientation (A) of the rows (34) is larger than along direction (B).
