摘要： A radiation image that has been stored in photostimulable phosphor screen comprising a divalent europium activated cesium halide is read out by stimulating the phosphor screen by means of stimulating radiation, detecting light emitted by the phosphor screen upon stimulation and converting the detected light into a signal representation of said radiation image. After read out the phosphor screen is erased by exposing it to erasing light emitted by at least one electroluminescent lamp or by an array of light emitting diodes.

摘要： A method of obtaining an electrical representation of a radiation image by means of at least one CCD sensor. A stimulable phosphor plate, the area of which is divided into at least two different portions, is exposed to a radiation image. Each of the portions is stimulated by light guided from a light source, the light having a wavelength within the stimulating wavelength range of the phosphor on the plate and causing the phosphor plate to emit stimulated light. The stimulated light from each phosphor plate portion is guided to at least one two-dimensional CCD sensor kept in a static position relative to the phosphor plate portion, such that the CCD detects the stimulated light. The detected stimulated light is converted into an electrical representation of the plate portion, and the electrical representation of each of the different plate portions is combined to form an electrical representation of the radiation image. When using fiber optics a high readout efficiency can be obtained using a broad range of light sources in continuous or pulsed mode.
