    摘要: 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).
