摘要： A method of obtaining an electrical representation of a radiation image by means of (a) CCD sensor(s) comprising the steps of :

exposing a stimulable phosphor plate to a radiation image,
dividing the area of the phosphor plate into at least two different portions,
stimulating each portions by light guided from a light source , the light having a wavelength within the stimulating wavelength range of the phosphor and causing the phosphor plate to emit stimulated light,
Guiding the stimulated light from said phosphor plate portion to at least one two-dimensional CCD sensor kept in a static position relative to the phosphor plate portion and detecting the stimulated light,
Converting the detected stimulated light into an electrical representation of the plate portion,
Combining the electrical representation of each of the different plate portions into the electrical representation of the radiation image.

When using fibre optics a high readout efficiency can be obtained using a broad range of light sources in continuous or pulsed mode.
