Radiation image read-out method and apparatus, and stimulable phosphor sheet

摘要

A stimulable phosphor sheet includes a stimulable phosphor layer in contact with a protective layer which is rigid and transparent. Stimulating light is projected onto the stimulable phosphor sheet from the protective layer side, stimulated emission emitted from the stimulable phosphor layer upon exposure to the stimulating light is detected by imaging the stimulated emission on a line sensor by an imaging lens from the protective layer side while moving the stimulable phosphor sheet relatively to the line sensor in a direction intersecting the direction in which the line sensor extends.
