    摘要： One surface of a stimulable phosphor sheet supported at a position for image recording is exposed to radiation, and a radiation image is stored on the stimulable phosphor sheet. Image readout is performed from the side of the other surface of the stimulable phosphor sheet supported at the position for image recording. Energy remaining on the stimulable phosphor sheet is then released by irradiating erasing light to an entire area of the stimulable phosphor sheet with a sheet-shaped erasing light source, which has uniform transmissivity to radiation and is located close to the one surface of the stimulable phosphor sheet supported at the position for image recording.

    摘要： A radiation image storage panel comprises a stimulable phosphor layer capable of emitting light when being exposed to stimulating rays, which cause the stimulable phosphor layer to emit the light in proportion to an amount of energy stored on the stimulable phosphor layer during exposure of the stimulable phosphor layer to radiation. The stimulable phosphor layer is adapted for radiating out the emitted light with an intensity distribution that is compressed in a direction, which is normal to a surface of the stimulable phosphor layer, and into an oblate distribution, which is flatter than a cos θ distribution.

    摘要： The image display device includes a liquid crystal display device having a liquid crystal panel and a backlight and a backlight controller for allowing the backlight of the liquid crystal display device to be bright when environment light is bright and allowing the backlight to be dark when the environment light is dark such that light leak (minimum luminance) which is defined by an extinction ratio of liquid crystal will not grow more than a specified degree. The image display device enables displayed images to be really discernible regardless of brightness of environment light (surrounding light).

    摘要： The digital radiation image evaluating method and apparatus record previously at least two radiation images with different exposed doses of the radiation, determine a value of evaluation of at least one of granularity and image quality of a digital radiation image for each of at least two digital radiation images obtained from at least two radiation images to obtain at least two values of evaluation, construct from at least two values of evaluation a correction curve for the value of evaluation to the exposed dose of the radiation and calculate by means of the correction curve the value of evaluation of the digital radiation image of a given dose exposed to the radiation. By the method and apparatus, the correct value of evaluation of the granularity and image quality of digital radiation image can be obtained for precisely predetermined doses exposed to radiation.

    摘要： Stimulating rays are linearly irradiated onto an area of a stimulable phosphor sheet, on which a radiation image has been stored by use of a stationary grid. Light emitted by the sheet is detected with a line sensor constituted such that a reciprocal of an array pitch of photoelectric conversion devices is larger than a value two times as large as a spatial frequency of stripe-like grid patterns recorded due to the stationary grid, which spatial frequency is taken with respect to an array direction of the photoelectric conversion devices. Filtering processing for removing the grid patterns is performed on an image signal having been outputted from the line sensor.

    摘要： A quantum confinement Stark effect (QCSE) optical modulator has a ridge stripe including a current confinement structure. The current confinement structure includes an AlInAs layer which is subjected to selective oxidation of Al content in the AlInAs layer. The current confinement structure is such that a pair of Al-oxidized regions of the AlInAs layer sandwiches therebetween a central un-oxidized region.
