| 摘要 |
The invention relates to an apparatus and method for the read-out of a latent image recorded on a stimulable phosphor sheet (1) by, for example, X-ray radiation. The apparatus comprises: a drum member (8) having a cylindrical circumferential surface; rotation means (22) for rotating (R) the drum member around the axis (3); means for maintaining the phosphor sheet (1) of a flexible material in the shape of the circumferential surface; a light source (4) for aiming stimulating light (6) at the phosphor surface (2); a photodetector (7) for detecting the light emitted from the phosphor surface under the effect of stimulation; and members (21) for moving (M), relative to the phosphor sheet, the stimulating light beam and the photodetector in a direction parallel to the axis. The cylindrical circumferential surface (5) is made up of the concave inner surface of the cylinder cavity (15) of the drum member, and the said transfer members (21) extend to the inside of the cylinder cavity (15) in order to introduce a stimulating beam and to aim it at the concave phosphor surface (2) of the phosphor sheet and to collect in the photodetector the light emitted from the phosphor surface.
