Embodiment 1
[0067] like Figure 1-8 As shown, the present invention provides a method for preparing a flexible scintillation screen, comprising the following steps:
[0068] 1) providing a substrate, and the substrate has an opposite first surface and a second surface, and a release layer is formed on the first surface;
[0069] 2) forming a flexible base layer on the surface of the release layer;
[0070] 3) preparing a scintillator layer on the surface of the flexible base layer, and the scintillator layer is used to convert the incident rays it receives into visible light;
[0071] 4) forming a protective layer covering the scintillator layer on the surface of the scintillator layer and the flexible base layer around the scintillator layer; and
[0072] 5) peeling to remove the release layer and the substrate connected to the release layer to obtain a flexible scintillation screen.
[0073] The preparation method of the flexible scintillation screen of the present invention will be ...
Embodiment 2
[0109] like Figure 9 and Figure 10 As shown, the present invention provides a method for preparing a radiation image sensor, comprising steps:
[0110] The flexible scintillation screen 1 is prepared by any one of the preparation methods in Example 1, and a sensor array 21 corresponding to the flexible scintillation screen is formed on the side close to the flexible base layer of the flexible scintillation screen to obtain a radiographic image Sensor 2, wherein the sensor array is used to convert the received visible light signal generated by the flexible scintillation screen into an electrical signal.
[0111] As an example, the flexible scintillating screen is attached to the sensor array by optically clear adhesive (OCA), so as to realize the coupling of the flexible scintillating screen and the sensor array.
[0112] As an example, the sensor array includes one of a flat panel detector and an imaging element.
