摘要： 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.

摘要： A first image signal representing a radiation image of an object is obtained by exposing a stimulable phosphor sheet, on which the radiation image has been stored, 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, the emitted light being detected. A second image signal representing the radiation image is thereafter obtained by again exposing the stimulable phosphor sheet to stimulating rays, the light emitted by the stimulable phosphor sheet being detected. Read-out conditions, under which the second image signal is to be obtained, and/or image processing conditions, under which the second image signal having been obtained is to be image processed, are adjusted on the basis of the first image signal. A storage device stores information representing a standard pattern of radiation images. A signal transforming device transforms the first image signal representing the radiation image into a transformed image signal representing the radiation image, which has been transformed into the standard pattern. A condition adjuster is provided with a neural network, which receives the transformed image signal and feeds out information representing the read-out conditions and/or the image processing conditions.
