EXPOSURE METHOD FOR PHOTOSTIMULABLE PHOSPHOR LAYER ON STORAGE PHOSPHOR SHEET AND UNIT FOR BIOCHEMICAL ANALYSIS USED FOR THE SAME AND STORAGE PHOSPHOR SHEET

摘要

PROBLEM TO BE SOLVED: To provide an exposure method for a photostimulable phosphor layer on a storage phosphor sheet which can prevent a noise caused by the scattering of an electron beam (-rays) from being generated in data for biochemical analysis. ;SOLUTION: In the exposure method for the photostimulable phosphor sheet on the storage phosphor sheet, a unit for biochemical analysis wherein a specific bond substance is dropped on one face, a substance originated from a living body labeled with a radioactive marker substance is bonded specifically to the specifically combined substance, a plurality of sporlike regions 3 are formed and an electrode 4 is installed on the other face and the storage phosphor sheet 10 in which the photostimulable phosphor layer 12 is provided in a region on one face corresponding to the plurality of spotlike regions in the unit for biochemical analysis and in which an electrode 11 is installed on the other face are made opposed to each other in a separated state, an electric field is applied in such a way that the unit for biochemical analysis becomes negative and that the storage phosphor sheet becomes positive, and the photostimulable phosphor layer is exposed by the radioactive marker substance.;COPYRIGHT: (C)2003,JPO
