    • A stimulable phosphor sheet is exposed to radiation carrying image information of an object, and a radiation image of the object is thereby stored on the stimulable phosphor sheet. The stimulable phosphor sheet is then 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 the radiation. The emitted light is photoelectrically detected, and an image signal representing the radiation image is thereby obtained. When the stimulable phosphor sheet is exposed to the radiation, the stimulable phosphor sheet is located such that it may make an angle falling within the range of 5 degrees to 60 degrees with respect to a plane, which is normal to the direction of travel of the radiation carrying the image information of the object. The image signal, which has been obtained by photoelectrically detecting the light emitted by the stimulable phosphor sheet, is corrected in accordance with the angle.
    • 将可刺激的荧光体片暴露于携带物体的图像信息的辐射,并且由此将物体的辐射图像存储在可刺激的荧光体片上。 然后将可刺激的荧光体片曝光以刺激光线,这使得可刺激的荧光粉片在其暴露于辐射期间与其上存储的能量的量成比例地发光。 发射的光被光电检测,从而获得表示放射线图像的图像信号。 当可刺激的荧光体片暴露于辐射时,可刺激的荧光体片被定位成使得它可以使得角度落在相对于平行于5度至60度的范围内的平面,该平面垂直于 辐射携带物体的图像信息。 通过光电检测由可刺激的荧光体片发射的光而获得的图像信号根据角度被校正。
