摘要： A device for reading out information stored in a storage layer (10), which facilitates a good reproduction quality of this information stored in the storage layer (10). The device (1) includes a radiation source (2) for emitting stimulation radiation (20). Using this stimulation radiation (20), the storage layer (10) is stimulated to emit an emission radiation that corresponds to the information stored in the storage layer (10). The device (1) further includes a receiving device (3) to receive this emission radiation emitted by the storage layer (10). A distance device (30, 56) for setting a pre-specified distance (28, 59) is located between the receiving device (3) and the storage layer (10). A drive device imparts relative movement in a transport direction (A) between the radiation source (2) and the receiving device (3), on one hand, and the storage layer (10) on the other.

摘要： An integrating optical collector with a diffusely reflective interior surface and with at least one wavelength selective absorptive filter located therein in a position that nearly bisects the interior of the collector. The filters are highly transmissive in a first wavelength band corresponding to an emission band of a storage phosphor, but highly absorptive in a second wavelength band corresponding to a stimulation band of the phosphor. The filter's wavelength selective properties and nearly bisecting position in the collector minimizes re-illumination of a phosphor at the stimulation wavelength, while permitting efficient radiation collection and detection at the emission wavelengths. A cylindrical collector with two parallel lengthwise slits permitting passage of the scan beam to the phosphor surface is preferred. Two filter plates on opposite sides of the slit may be used, which can either be parallel to each other and to the slits or oriented at an angle with respect to each other.

摘要： In a radiation image acquisition apparatus that obtains a radiation image recorded on a stimulable phosphor layer having a plurality of arranged cells, the quantity of stimulated emissions from the stimulable phosphor within each cell is obtained precisely for each cell as a digital image signal. A radiation image conversion panel comprising a phosphor layer formed of multiple cells filled with stimulable phosphor having recorded on the surface thereof a radiation image is scanned with a stimulating light beam by a scanning unit, and the stimulated emissions caused thereby are photoelectrically detected as an analog image signal by a photoelectrical amplifier. The signal component representing the partition walls is recognized, and the component of the analog image signal obtained between the recognized signal components representing the cell partition walls is digitized and a digital image signal is obtained.

摘要： In a radiation image recording/read-out apparatus, a stimulable phosphor sheet having a reflective layer which is not longer than 5 &mgr;m 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.

摘要： Stimulating light is projected onto a stimulable phosphor sheet while the image read-out mechanism is being moved in a sub-scanning direction relatively to the stimulable phosphor sheet and stimulated emission emitted from the stimulable phosphor sheet upon exposure to the stimulating light is detected by the photoelectric converter. The image read-out mechanism is moved back and forth in the sub-scanning direction. First and second image signals are obtained on the basis of the stimulated emission detected during the forward and backward movements of the image read-out mechanism, and an image signal representing the radiation image on the stimulable phosphor sheet is obtained on the basis of the first and second image signals.

摘要： A process for recording a radiation image on a radiation image storage panel containing stimulable phosphor particles and then reproducing the radiation image by the double side reading system is favorably performed employing a radiation image storage panel containing stimulable phosphor particles in which the stimulable phosphor particles vary in their mean particle sizes in the depth direction of the storage panel in such manner that the mean particle size on one surface side is smaller than the mean particle size on the other surface side, preferably under the condition that stimulating rays are applied onto the storage panel on the surface side having the phosphor particles of the smaller mean particle size to excite the phosphor particles in the storage panel.
