摘要： A stimulable phosphor sheet, on which a radiation image has been stored, is exposed to stimulating rays, which cause it to emit light in proportion to the amount of energy stored thereon during its exposure to radiation. The light emitted by the front surface of the stimulable phosphor sheet and the light emitted by the back surface of the stimulable phosphor sheet, are detected photoelectrically. The image signal components of the two image signals are subtracted from each other, which represent corresponding picture elements on the front and back surfaces of the stimulable phosphor sheet, difference values being thereby obtained. A judgment is made as to whether each of the difference values falls or does not fall within a predetermined range. In cases where a difference value is judged as being outside the predetermined range, it is determined that an abnormal signal component is contained in at least either one of the two image signals.

摘要： A plurality of image signals are obtained, which represent a radiation image of a single object or radiation images of the single object, and which have different frequency characteristics, each of the image signals being made up of a series of image signal components. The image signal components of the plurality of the image signals, which image signal components represent corresponding picture elements, are weighted with predetermined weight factors. The weighted image signal components of the plurality of the image signals, which image signal components represent corresponding picture elements, are added to one another, and an addition signal is thereby obtained. The value of the weight factor with respect to the frequency components, which have a low signal-to-noise ratio, is rendered smaller than the value of the weight factor with respect to the frequency components, which have a high signal-to-noise ratio, in accordance with the frequency characteristics of each of the image signals.
