<p>A stimulable phosphor screen (12) storing a radiation image is read by exposing the phosphor screen to stimulating rays, thereby causing the phosphor screen to emit light in proportion to the amount of stored energy. The emitted light is detected by a light detector (34, 32) to obtain an image signal of the radiation image. During the reading process, the phosphor screen is stimulated by light from a light source (16', 28) having a wavelength or wavelengths of about 570 nanometers to about 620 nanometers. After being read with such a light source, the phosphor screen has significantly reduced energy level, thereby allowing for a reduction in the total time required to erase the phosphor screen and prepare it for reuse.</p> |
