    Abstract: An image is reproduced on a light emission display system such as a CRT by use of an image signal obtained from the image. The image to be reproduced is an image which is taken by use of an irradiation field stop and the image signal is obtained from the image in such a manner that image signal components obtained from an area outside the irradiation field becomes lower in signal level than those obtained from the area inside the irradiation field. The image is reproduced as a visible image on the light emission display system according to gradation properties where the brightness level of a picture element becomes higher as the level of the image signal component for the picture element becomes lower. A picture element the signal level of the image signal component for which is not higher than a predetermined threshold value is displayed at a brightness within a predetermined lowest brightness level range.

    Abstract: Two radiation images of a single object, which comprises a soft tissue and a bone tissue, are formed respectively with two kinds of radiation having different energy distributions, the two radiation images being to be subjected to energy subtraction processing. The energy subtraction processing is carried out on the two radiation images, and a bone image, in which the pattern of the bone tissue in the object has been extracted or emphasized, is thereby formed. Numerical information concerning the density of the bone constituent is obtained in accordance with the bone image. A bone trabecula pattern emphasizing process is carried out on the bone image, and information representing the form of bone trabeculae is thereby obtained.

    Abstract: A tube voltage, at which each of at least two kinds of radiation having different energy levels is produced, is adjusted such that a ratio between a change in the image density of bones, which change occurs due to a beam hardening phenomenon of the radiation having a high energy level, and a change in the image density of the bones, which change occurs due to a beam hardening phenomenon of the radiation having a low energy level, may become approximately equal to a ratio between subtraction factors employed in a subtraction process. Each of at least two kinds of the radiation, each of which has been produced at the thus adjusted tube voltage, is irradiated to one of at least two stimulable phosphor sheets, and radiation images of the object are thereby stored on the stimulable phosphor sheets. The radiation images are then photoelectrically read out, and digital image signals are thereby obtained. Image signal components of the digital image signals, which represent corresponding picture elements in the radiation images, are then subtracted from each other, and a difference signal is thereby obtained which represents the image of only the bones represented by the radiation images.

    Abstract: At least two stimulable phosphor sheets are exposed to at least two kinds of radiation, which have different energy distributions, without an object intervening between the stimulable phosphor sheets and a source of the radiation. The stimulable phosphor sheets are then exposed to stimulating rays, which cause them to emit light in proportion to the amount of energy stored thereon during their exposure to the radiation. The light emitted is photoelectrically detected, and digital image signals are thereby obtained, which are to be used for compensating for nonuniformity in how the radiation is irradiated to the stimulable phosphor sheets. Digital image signals representing radiation images of an object stored with at least two kinds of radiation and the corresponding digital image signals for the compensation are then subtracted from each other, and digital image signals are obtained which are free of noise due to nonuniformity in how at least two kinds of radiation are irradiated to the stimulable phosphor sheets. The digital image signals, which are free of noise, are then subtracted from each other, and a difference signal is thereby obtained which represents the image of only the bones represented by the radiation images. Bone calcium in the bones is quantitatively analyzed by utilizing the difference signal.

    Abstract: Image signals are subjected to a first signal compression processing which is carried out with a small factor of compression. The compressed image signals, which are obtained from the first signal compression processing, are recorded on a first recording medium. When a predetermined period has elapsed after a compressed image signal obtained from the first signal compression processing was recorded on the first recording medium, or when the frequency with which the compressed image signal is read from the first recording medium has become lower than a predetermined value, the compressed image signal is read out from the first recording medium. The image signal, which has been read out from the first recording medium, is subjected to a second signal compression processing which is carried out with a large factor of compression. The compressed image signal, which is obtained from the second signal compression processing, is recorded on a second recording medium. Thereafter, the compressed image signal, for which the predetermined period has elapsed after it was recorded on the first recording medium or for which the frequency has become lower than the predetermined value, is erased from the first recording medium.
