るＸ線画像作成方法を提供するものである。For imaging using silver halide film, the silver halide film is placed behind the subject and X-rays are irradiated from the opposite side (in front of the subject), then the exposed silver halide film is moved to the developing room and developed in a dark room. This is the way to do it. This method requires only an X-ray source when taking pictures and does not require any other special equipment, but it is complicated and requires a long processing time because it requires chemical processing in the developing and fixing steps. There are disadvantages such as the generation of waste liquid containing harmful substances. Furthermore, although this method is generally suitable for photographing skeletal parts, ie, hard tissues, such as the head, chest, hands, and feet, it is not very suitable for photographing soft tissues such as muscles, stomach, and intestines. On the other hand, xeroradiography and ionography obtain an X-ray image of the subject as an electrostatic latent image, so when this latent image is developed, the edge effect, which is well known in electrophotography, can cause damage to soft tissue, etc. It is possible to obtain an image with good discrimination in contrast areas. However, xeroradiography generally has poor sensitivity due to the low photon efficiency of the photoconductor, which goes against the desire to reduce radiation exposure, and the surface of the photoconductor must be charged prior to imaging. Therefore, it has the disadvantage that it is necessary to take an image before the dark decay of the charge becomes large. In addition, ionography is based on the drift of ion pairs towards the electrodes, which occurs when the gas or insulating liquid that exists between electrodes that are placed opposite each other with a gap absorbs X-rays, so the gap distance is large. The resolution may decrease due to the scattering of secondary electrons, or the equipment may become bulky in order to maintain airtightness if using gas, or to maintain stable insulation if using insulating liquid. Moreover, it is not easy to take pictures because it requires voltage application and charging prior to taking pictures. The present invention was developed in view of the above circumstances, and it has high resolution and sensitivity, and can be easily photographed like silver halide film, and can easily visualize X-ray images anytime and anywhere with a heating device or light irradiation device. The purpose of the present invention is to provide an X-ray image creation method that can perform X-ray image generation and also perform offset printing if necessary.

Due to chemical reactions on the solid surface, several EVs are removed from the solid surface.
The following low energy electron emission occurs. This phenomenon can be described as exoelectron emission (ExOelectrOnemissiOnl).
This electron emission (abbreviated as EEE) attenuates over time after the surface treatment or irradiation of the solid is completed, but even after it has completely attenuated, electron emission occurs again due to stimulation such as light irradiation or heating. The former is external emission caused by optical stimulation (

It is called ``YSEE'' for short. The present invention utilizes the storage and readout characteristics of solid surfaces through treatment and radiation irradiation as described above. Next, we will briefly discuss the reversible redox coloring reaction of electrochromic materials that visualizes the emitted electron image.

Ru. This reaction is explained as in equation (1). That is, viologen is dissociated into a dication and a halogen anion in an aqueous solution, and when a potential difference is applied between the electrodes, the viologen dication is attracted to the cathode, receives electrons on the cathode surface, and generates a blue radical cation.

オフセット印刷できるＸ線画像作成方法に関する。Then, due to the hydrophobicity of the alkyl group R, it becomes instantaneously insoluble in water and precipitates on the surface of the cathode in the form of a reddish-purple film. On this cathode surface, a dye layer is deposited.[2] The part without is hydrophilic, but the dye part is lipophilic. In order to erase this dye layer, it is sufficient to apply a voltage of opposite polarity between the electrodes or to short-circuit both electrodes. In this way, the viologen ions release electrons to the cathode, returning to the original colorless state, and the reddish-purple color disappears. The present invention relates to an X-ray image creation method that utilizes these phenomena, does not require voltage application, can be easily visualized anytime and anywhere after X-ray irradiation, and can offset print an X-ray image if necessary.

．． Add and mix 1 to 5 m01% of a lithium compound or a sodium compound. The lithium compound or sodium compound may be sulfate, hydrochloride, nitrate, or any other compound. Mixing may be carried out wet or dry, but wet mixing is preferable since uniform mixing is possible. The compound thus obtained was 1200 to 1
Bake at a temperature of 800'C for over 1 hour. At this time, air or 02 gas is flowed into the furnace to maintain an oxidizing atmosphere. After baking, let it cool naturally and take it out.

子放出部材３にさらに湿し水６を塗布する。FIG. 5 shows glow curves when BeO:Li, which is one of the exoelectron-emitting substances used in the present invention, is irradiated with 137Cs/γ rays at 100 mR and heated. In the figure, curves A, b, c is 2n101% Li in BeO, respectively.
When 2SO4 is added, the contents of Li ions to Be ions correspond to 1.1%, 3.1%, and 0.05%. As you can see from this figure, the heating temperature is 300~3
70°C is suitable. As described above, a peak of electron emission appears at a specific temperature depending on the characteristics of the exoelectron-emitting material, so the heating temperature range may be changed as appropriate depending on the material used. When the exoelectron emitting member 3 is heated in this way, exoelectrons are emitted from the surface of the exoelectron emitting material 2 in accordance with the amount of X-ray irradiation, and the reaction as described above occurs in the electrochromic material 4, and the exoelectrons are A dye layer 5 is deposited on the surface of the electron-emitting material 2 (FIG. 2). In this way, an X-ray image can be obtained by simply applying the electrochromic substance 4 to the surface of the exoelectron emitting member 3 that has been irradiated with X-rays and heating the exoelectron emitting member. To transfer this X-ray image to paper or other final image-forming material, dampening water 6 is further applied to the exoelectron-emitting member 3 visualized with the electrochromic material 4.

い。As explained above, the areas that are not visualized are hydrophilic, so the dampening water 6 will adhere to them. Next, when the offset ink 7 is applied, since the dye layer visualized by the electrochromic substance 4 is lipophilic, the offset ink 7 is deposited corresponding to the image (FIG. 3). The image formed by this offset ink 7 is transferred to a normal rubber cylinder 8, and an impression cylinder 9
is transferred to a final image forming member 10 such as paper (FIG. 4). According to the present invention, the exoelectron-emitting member after X-ray irradiation can be carried freely, and the electrochromic substance can be coated while being heated in a place where there is a heating device, or the exoelectron-emitting member can be heated after being coated with the substance. Simply applying an electrochromic substance to the surface of the exoelectron emitting material and heating it can visualize an X-ray image, and a developing chamber that can treat wastewater like silver halide film and a zero radio. There is no need for charging or voltage application devices such as ionography or ionography.
