    摘要: Disclosed is a solid state detector which comprises a photo-conductive layer for generating charges upon irradiation of recording light and a substrate laminated to the photo-conductive layer, the substrate having a thermal expansion coefficient different from that of the photo-conductive layer. The solid state detector prevents deformation and breakdowns due to temperature changes of environments. Specifically, the solid state detector comprises a photo-conductive layer and a substrate laminated to the photo-conductive layer, the substrate having a thermal expansion coefficient smaller than that of the photo-conductive layer. In the solid state detector a deformation suppression layer, which has a thermal expansion coefficient smaller than that of the photo-conductive layer and suppresses deformation resulting from thermal expansion of the photo-conductive layer and the substrate, is laminated on a side of the photo-conductive layer opposite from the side of the substrate.

    摘要: In a radiation image data obtaining method and a radiation image data obtaining apparatus, quality degradation at the periphery of an image is prevented after subtraction processing. Radiation emitted from a radiation source and having passed through a subject is irradiated onto a detector. An image signal in accordance with the intensity of the radiation is output from a detection layer at the front. Meanwhile, a portion of the radiation which has not been converted into visible light by a scintillator out of the radiation irradiated onto the detection layer passes through the detection layer and reaches another detection layer at the rear. An image signal is output from the layer at the rear. The image signal from the rear is input to size correction means and a size correction operation is carried out in the means so that the sizes of images represented by the image signal from the front and an image signal after the correction agree.

    摘要: There is provided a collimating plate including a transparent support, a multiple of light transmitting spheres fixed to the support in partial contact therewith and a light blocking area that blocks passage of light through areas other than light transmitting areas composed of areas of contact between the support and the spheres and nearby areas. There is also provided a backlight system including the collimating plate and a housing that is optically closed by the collimating plate and that includes an inner surface having reflecting properties. They can produce adequately convergent collimated light the intensity of which drops by 50% at angles of no more than ± 15 degrees, thereby realizing a liquid-crystal display that can provide a sufficiently good contrast ratio over a wide range of viewing angles to be advantageously used in medical applications.

    摘要: In image recording, density correction is performed by an improved method in which the image densities on a density correcting reference chart that have known densities which are associated with a visual density are measured with a densitometer for setting the density correcting conditions, the correcting conditions for correcting the values of measurement with the densitometer such that they coincide with the image densities on the reference chart are constructed from the image densities on the reference chart and the values of measurement with the densitometer, and the density correcting conditions are set in accordance with the constructed density correcting conditions. Alternatively, the density correcting conditions are set in consideration of a threshold for color formation to occur in the thermal recording material or the maximum heating time in thermal recording is controlled. In accordance with these methods and using an apparatus in which they are implemented, appropriate density correcting conditions can be set irrespective of the individual differences between densitometers used in the setting operation and satisfactory tones can be reproduced even in highlight density areas, thereby achieving consistent formation of high-quality images which feature effective reproduction of the desired gradation.

    摘要: In the improved thermal recording method in which image data supplied from an image data supply source are subjected to specified image processing jobs and in which a thermal head is driven in accordance with the processed image data so as to perform thermal recording, image processing jobs are performed in a specified order such that sharpness correction and tone correction are followed by shading correction and correction of resistance values which, in turn are followed by compensation for temperature elevation, provided that calculation treatment of respective values of the image data for the compensation for temperature elevation is performed either prior to or after either one of the corrections that are performed subsequent to the tone correction. It is preferred that black ratio correction and/or load variation correction are also performed after the shading correction and the correction of resistance values, and prior to the compensation for temperature elevation. The improved thermal recording apparatus is used to carry out the thermal recording method described above. According to these apparatus and method, high quality images can be recorded consistently.

    摘要: Corrected recording data for a present pixel are generated from recording data stored in an image memory based on recording data for pixels preceding, following, above, and beneath the present pixel, and stored in a corrected image memory. A laser diode is energized according to the corrected recording data to output a laser beam for thereby recording an image on a thermosensitive recording medium. Since the recording data have been corrected taking into account the thermal energy from the adjacent pixels, the image thus recorded on the thermosensitive recording medium is highly accurate at a high speed.
