| 摘要 |
The object of the present invention is an cascaded ionizing radiation converter, comprising the first conversion stage, transforming ionizing radiation into non-ionizing electromagnetic radiation, the second conversion stage transforming non-ionizing electromagnetic radiation into an electrical charge, and the third conversion stage transforming the generated electric charge into the change of potential controlling the liquid crystal cell, wherein the first conversion stage is a radioluminescent layer, preferably Lu2O3:Eu layer, the second conversion stage is a photoconductive material layer, preferably amorphous selenium or poly (3-hexylthiophene ) layer, and the non-ionizing electromagnetic radiation emission spectrum of the first conversion stage corresponds with the non-ionizing electromagnetic radiation absorption spectrum of the second conversion stage; And an imaging diagnostic apparatus using cascaded ionizing radiation converter. |
