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 stimulable phosphor sheet, on which a radiation image of an object has been stored, is exposed 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 is detected by a photoelectric read-out device, and an image signal representing the radiation image is thereby obtained. Threshold value processing is carried out in accordance with the obtained image signal, and a prospective abnormal pattern is thereby detected from the radiation image. A predetermined threshold value, which is used in the threshold value processing for detecting the prospective abnormal pattern, is set to be a small value as the amount of change in the image signal corresponding to the region in the vicinity of the prospective abnormal pattern becomes large.
