| 摘要 |
The proposed group of inventions relates to methods for depositing fluorescent coatings on screens, by which an image is detected and / or converted, in particular, to methods of forming a structured scintillator on the surface of a photodetector intended for the detection of X-ray or gamma radiation, hereinafter referred to as the detected radiation, and to devices for obtaining an X-ray image, or an image obtained by detection of gamma radiation, particularly to devices for X-ray mammography and tomosynthesis. A method for forming a structured scintillator on the surface of a pixelated photodetector, wherein according to embodiment 1, at least one structural element is formed directly on the surface of the photodetector, the material of which is deposited by using a two-axis or a three-axis means for discrete deposition of liquid or heterogeneous substances. According to embodiment 2 of the method of forming a structured scintillator on the surface of a pixelated photodetector, at least one structural element is formed directly on the surface of the photodetector previously segmented with a hydrophobic insulating coating consistent with interpixel insensitive areas so that geometric shapes of depositing the material of the structural element are formed under the action of surface tension forces of the boundary of hydrophobic-hydrophilic areas of the photodetector surface. In addition, the group of inventions includes two embodiments of scintillation detectors. The inventions of the proposed group improve the manufacturability with simultaneous extension of the scope of application. |
