Abstract
In a radiation image recording/read-out apparatus, a stimulable phosphor sheet having a reflective layer which is not longer than 5 μm in scattering length and is interposed between a stimulable phosphor layer and a support layer is used. Radiation is projected onto the stimulable phosphor sheet from the support layer side, and stimulating light is projected onto the stimulable phosphor sheet from the stimulable phosphor layer side. Stimulated emission, emitted from the stimulable phosphor layer upon exposure to the stimulating light, is detected from the stimulable phosphor layer side.
Claims9
A radiation image recording/read-out method comprising the steps of
- projecting radiation onto a stimulable phosphor sheet, having a reflective layer which is not longer than 5 μm in scattering length and is interposed between a stimulable phosphor layer and a support layer, from the support layer side of the stimulable phosphor sheet,
- projecting stimulating light onto the stimulable phosphor sheet, which has been exposed to the radiation, from the stimulable phosphor layer side of the stimulable phosphor sheet, and
- detecting stimulated emission, emitted from the stimulable phosphor layer upon exposure to the stimulating light, from the stimulable phosphor layer side of the stimulable phosphor sheet.
A radiation image recording/read-out apparatus comprising
- a stimulable phosphor sheet having a reflective layer which is not longer than 5 μm in scattering length and is interposed between a stimulable phosphor layer and a support layer,
- a radiation projecting means which projects radiation onto the stimulable phosphor sheet from the support layer side of the stimulable phosphor sheet, and
- a read-out means which projects stimulating light onto the stimulable phosphor sheet, which has been exposed to the radiation, from the stimulable phosphor layer side of the stimulable phosphor sheet and detects stimulated emission, emitted from the stimulable phosphor layer upon exposure to the stimulating light, from the stimulable phosphor layer side of the stimulable phosphor sheet.
A stimulable phosphor sheet comprising a reflective layer which is not longer than 5 μm in scattering length and is interposed between a stimulable phosphor layer and a support layer, wherein radiation is projected onto the stimulable phosphor sheet from the support layer side, stimulating light is projected onto the stimulable phosphor sheet from the stimulable phosphor layer side and stimulated emission, emitted from the stimulable phosphor layer upon exposure to the stimulating light, is detected from the stimulable phosphor layer side of the stimulable phosphor sheet.
