摘要： A laser diode pumped solid state laser is provided with a first temperature control circuit which controls the temperature of the laser diode to a predetermined value and a second temperature control circuit which controls the temperature of the resonator of the solid state laser to a predetermined value. When the solid state laser is in a steady state, an automatic power control is carried out for keeping the light output of the solid state laser at a reference output value. When a predetermined command is issued, the automatic power control is switched to an automatic current control for keeping the electric current flowing through the laser diode at a reference current value. A temperature of the laser diode at which the light output of the solid state laser is maximized is detected while changing the temperature of the laser diode, and the first temperature control circuit controls the temperature of the laser diode to the detected temperature. A temperature of the resonator at which the light output of the solid state laser is maximized is detected while changing the temperature of the resonator, and the second temperature control circuit controls the temperature of the resonator to the detected temperature.

摘要： An image recording sheet and a solid-state image detector are used. The sheet has a stimulable phosphor layer laminated on a base, and the solid-state image detector includes a photoconductive layer containing amorphous selenium as its main component and electrodes disposed on opposite sides of the photoconductive layer. An electric field is applied across the photoconductive layer so that avalanche amplification is obtained within the photoconductive layer. The sheet is scanned under the electric field with stimulating light of wavelength of about 600 nm, and photostimulated luminescence light of wavelength of about 400 nm emitted from the fluorescent layer is incident on the photoconductive layer via an optical guide and a stimulating light cut filter. Electric charge generated within the photoconductive layer is detected by a current detecting circuit, whereby a radiation image signal is obtained.

摘要： Initial image data having a pixel size smaller than a pixel size of a final image are obtained by using line sensors arranged in a main scan direction and a vertical scan direction, and the final image becomes of high quality by processing the initial image data to prevent the image from becoming uneven. Integration processing means carries out a first conversion process to convert the initial image data comprising signals detected by the line sensors into data for pixels divided in the main scan direction. The integration processing means carries out a second conversion process in which, whenever the data are obtained for three consecutive pixels in the main scan direction, the data are added to become data for one pixel of the final image. The data for the final image are then subjected to an equalization process such as dark current correction carried out by a correction means.

摘要： A stimulable phosphor sheet, on which radiation image information has been stored, is exposed to stimulating rays, which cause the stimulable phosphor sheet to emit light in proportion to the amount of energy stored thereon during its exposure to radiation. Light, which is emitted from opposite surfaces of the stimulable phosphor sheet when the stimulable phosphor sheet is exposed to the stimulating rays, is detected, and two original image signals representing the radiation image information are acquired. A read-out sensitivity and/or a read-out gain with respect to at least either one surface side of the stimulable phosphor sheet at the time of the image signal acquisition is controlled in accordance with specifications of the stimulable phosphor sheet.

摘要： A stimulable phosphor sheet, on which a radiation image has been stored, is exposed to stimulating rays, which cause it to emit light in proportion to the amount of energy stored thereon during its exposure to radiation. The light emitted by the front surface of the stimulable phosphor sheet and the light emitted by the back surface of the stimulable phosphor sheet, are detected photoelectrically. The image signal components of the two image signals are subtracted from each other, which represent corresponding picture elements on the front and back surfaces of the stimulable phosphor sheet, difference values being thereby obtained. A judgment is made as to whether each of the difference values falls or does not fall within a predetermined range. In cases where a difference value is judged as being outside the predetermined range, it is determined that an abnormal signal component is contained in at least either one of the two image signals.
