摘要： Markers for providing reference points or lines are recorded together with radiation images on stimulable phosphor sheets in a position fixed with respect to the radiation images. The stimulable phosphor sheets are scanned with stimulating rays, and the spatial coordinates of reference points or lines are detected from digital data of the images detected from light emitted from the stimulable phosphor sheets. Rotation and shift among the radiation images are calculated based on the reference points or lines. One of the radiation images is rotated on the digital data when positional deviation exists and moved on the digital data when positional deviation exists. Subtraction of the image data is then conducted among the corresponding picture elements of the radiation images to extract an image of a specific portion of the radiation images.

摘要： A linear stimulating ray source produces stimulating rays and linearly irradiates them to a portion of a stimulable phosphor sheet, on which a radiation image has been stored. A photoelectric read-out system divides light, which is emitted from the portion of a front surface of the stimulable phosphor sheet exposed to the stimulating rays and/or the portion of a back surface of the stimulable phosphor sheet corresponding to the portion of the front surface exposed to the stimulating rays, into picture elements along a length direction of the portion exposed to the stimulating rays, and photoelectrically reads out the divided picture elements by arraying them in a two-dimensional form. A scanning system moves the stimulable phosphor sheet with respect to the linear stimulating ray source and the photoelectric read-out system and in a direction, which is approximately normal to the length direction of the portion exposed to the stimulating rays.

摘要： An operation of an iris filter is carried out on an original image signal representing an image, and the degree of centralization of gradients of the original image signal with respect to a picture element is thereby calculated, each of picture elements constituting the image being taken as the picture element. An image portion, which is associated with a high degree of centralization, in the image is detected in accordance with the calculated degree of centralization. Image emphasis processing is then selectively carried out on the detected image portion. Alternatively, a morphology operation is carried out on an original image signal Dorg by using a multiply structure element Bi and a scale factor .lambda., and a morphology signal Dmor is thereby obtained. The morphology signal Dmor represents whether each of picture elements constituting the image is or is not the one corresponding to an image portion, at which the original image signal Dorg fluctuates in a spatially narrower range than the multiply structure element Bi. Image emphasis processing is then carried out on the original image signal Dorg and in accordance with the morphology signal Dmor.

摘要： An energy subtraction processing method and apparatus for radiation images includes irradiating radiation, which has a predetermined energy range, into an object in a recording unit, and irradiating the radiation, which has passed through the object, to a recording medium capable of recording a plurality of radiation images during its exposure to radiation with different energy distributions. A plurality of radiation images of the object are thereby recorded on the recording medium. From the recording medium on which the radiation images have been recorded, a plurality of image signals are obtained by a read-out unit. The image signals represent the radiation images of the object. A modulation transfer function (MTF) correcting process is carried out on the image signals in an operation unit such that differences between MTF's of the radiation images of the object may be eliminated. Subtracting operations are then carried out in the operation unit on image signals, which are obtained from the MTF correcting process.

摘要： A radiation image of an object is formed with radiation, which has passed through the object. The radiation image is then photoelectrically read out, and an image signal made up of a series of image signal components representing the radiation image is thereby obtained. Frequency processing is carried out on the image signal in accordance with a predetermined emphasis coefficient .beta.. When the frequency processing is carried out on image signal components corresponding to a peripheral region in the radiation image, which peripheral region has a predetermined width, the value of the emphasis coefficient .beta. used during the frequency processing is decreased monotonously from a value for an image signal component corresponding to a position on the radiation image, which position is closer to the middle part of the radiation image, to a value for an image signal component corresponding to a position on the radiation image, which position is closer to the exterior of the radiation image. The frequency processing is thus carried out such that an artifact occurring at peripheral regions in a reproduced visible image may become imperceptible.
