摘要： An irradiation image erase unit (100) for erasing a residual image from a stimulable phosphor sheet with erasure light is disposed in the vicinity of an image read-out unit (62) which converts light emitted from the stimulable phosphor sheet upon stimulation thereof into an electric signal. The irradiation image erase unit comprises a box- shaped casing (100) having a slot for passage of the stimulable phosphor sheet therethrough into the casing, and erasure light sources disposed in the casing for emitting the erasure light. A pair of rollers (104) is mounted on the casing adjacent to the slot for introducing the stimulable phosphor sheet into the casing. The rollers or a cover enclosing the rollers serves to prevent the erasure light from leaking out of the casing toward the image read-out unit. The casing has reflective inner surfaces for reflecting the erasure light effectively, and a heat radiator for discharging out heat generated by the erasure light sources as they are energized.

摘要： 5 Stimulable phosphor sheets (30) are circulated through an image recording section (40) for recording radiation images on the stimulable phosphor sheets, an image read-out section (50) for scanning the stimulable phosphor sheets by stimulating rays (52) and detecting light emitted . thereby upon stimulation, and an erasing section (70) for releasing radiation energy remaining in the stimulable phosphor sheets. Time elapsed after the radiation energy remaining in each stimulable phosphor sheet was released is measured, and image recording on each stimulable phosphor sheet is detected. A time measurement signal and an image recording detection signal are sent to a control device which activates a sheet circulating and conveying system to send the stimulable phosphor sheet to the erasing section when the time elapsed after releasing of the radiation energy remaining in the stimulable phosphor sheet reaches a predetermined length prior to image recording on the stimulable phosphor sheet.

摘要： In a radiation image recording and reproducing system using a stimulable phosphor sheet (4), a voltage generated at a bleeder resistor of a photomultiplier (7) for conducting image read-out is detected at the step of radiation image read-out at least for the stimulable phosphor sheet or a portion thereof where the level of X-ray exposure amount is higher than a predetermined level, and the exposure amount of erasing light (16) is controlled on the basis of the detected voltage. Or, the erasing light exposure amount is controlled on the basis of an output current of the photomultiplier when the output current is equal to or smaller than a predetermined value which is smaller than a saturated value of the output current, and the bleeder resistor voltage of the photomultiplier is detected and the erasing light exposure amount is controlled on the basis of the detected voltage when the output current of the photomultiplier is larger than the predetermined value.

摘要： In a radiation image recording system in which a radiation image is recorded on a stimulable phosphor sheet (2) and then read out and reproduced into a visible radiation image, a high-power light source (20) is built in the system to erase the noise due to the previously stored radiation image and the fog in the phosphor sheet by a single erasing operation immediately before the phosphor sheet is to be used to record thereon a radiation image. The light source (20) has an exposure amount of at least 500,000 1x·sec. and is positioned between a phosphor sheet feeding section (3) and a section (10) where a radiation image is recorded on the sheet. The system is also provided with a mechanism (14) for sending the phosphor sheet from the recording section to a sheet receiver (5) or radiation image read out and reproducing apparatus.

摘要： An apparatus is described for erasing the noise due to the previously stored radiation image and the fog in a stimulable phosphor sheet (2) used in a radiation image recording and reproducing system in which a radiation image is recorded in the stimulable phosphor sheet (2) and then read out and reproduced on a recording material. The apparatus erases the noise in a single erasing operation when stimulable sheets (2) are taken up one at a time out of their reservoir (3) and each is loaded into a cassette (11) used for the recording of a radiation image. The apparatus comprises a high-power light source (10) for erasing the noise, which is provided between the aperture (6) of the reservoir (3) from which the stimulable phosphor sheets (2) are taken up and the section at which the sheets (2) are loaded into the cassette (11).

摘要： An image reading apparatus (10) includes a casing (12) having a side panel which has a cassette loading slot (14) defined therein for loading a cassette (20) therein. A stimulable phosphor sheet (18) stored in the cassette (20) loaded in the cassette loading slot (14) is removed from the cassette (20) and fed vertically downwardly along a first vertical feed path (30). Radiation image information recorded in the stimulable phosphor sheet (18) is read by a reader (32). Thereafter, the stimulable phosphor sheet (18) is stored back into the cassette (20), which is then delivered toward a cassette unloading slot (16) by a sliding displacement mechanism (24). The stimulable phosphor sheet (18) is removed again from the cassette (20), and fed along a second vertical feed path (52) for an eraser (54) to erase remaining radiation image information from the stimulable phosphor sheet (18).
