    摘要： In a radiation image read-out system wherein a radiation image recorded on a recording medium through an irradiation field stop is read out and the read-out image signals are subjected to an image processing, the image processing conditions are determined or adjusted based on the histogram of the image signals. In a radiation image read-out system wherein a radiation image is recorded on a recording medium through an irradiation field stop and preliminary read-out is conducted prior to final read-out, and the image signals read out by the final read-out are subjected to an image processing, final read-out conditions and/or image processing conditions are determined or adjusted based on the histogram of the image signals obtained by the preliminary read-out. In both cases, prospective edge point signals, which are considered to be signals representing edge portions of an irradiation field on the stimulable phosphor sheet, are detected from the image signals. A region of a level lower than a characteristic value representing the prospective edge point signals is removed from the histogram, and the final read-out conditions and/or the image processing conditions are adjusted based on the histogram outside of the lower level region.

    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.

    摘要： A method of recognizing (distinguishing) a radiation field is provided for radiation image recording and reproducing systems that utilize stimulable phosphor sheets. With respect to the process of reproducing radiation image information stored on the phosphor sheet by scanning it with stimulating rays, such as laser light, the present method allows the radiation field on the sheet to be precisely distinguished, reducing the influence of undesirable stored image energy emissions from outside the prescribed region. This enables radiation images to be obtained that are more effective for diagnostic purposes. The method can also be applied for the recognition of irregularly shaped radiation fields, which hitherto has been extremely difficult.
