摘要:
A radiation image storage panel having a stimulable phosphor layer provided on a substrate with a honeycomb structure constituted of a number of cells partitioned by wall members filled with the stimulable phosphor is prepared by forming the substrate for phosphor layer by casting in a mother mold or etching of the substrate and filling the cells on the substrate with the stimulable phosphor. This radiation image storage panel can give images of markedly improved sharpness.
摘要:
In a radiographic image conversion method in which a stimulating light is irradiated to a panel storing a radiation energy in the form of an image to reproduce and then to read out the image, the response speed of a stimulation and the reading speed of a radiographic image area increased by making use of (1) a phosphate type phosphor having the composition, xM.sub.3 (PO.sub.4).sub.2.NX.sub.2 :yA or M.sub.3 (PO.sub.4).sub.2 :yA, which is a highly sensitive phosphor capable of readily releasing the stored energy when a stimulating light is irradiated to the phosphor, and (2) the stimulating light having the range of the wavelengths from a visible ray of not shorter that 500 nm to an infrared ray.
摘要:
A method for reading out a radiographic image by detecting the stimulated emission having an extremely high intensity. This high intensity is obtained by the choice of the Ar.sup.+ laser beam as a stimulating ray.
