1 is a block diagram of an X-ray apparatus according to an exemplary embodiment of the present invention.

Referring to FIG. 1, the X-ray apparatus 2000 may include an electromagnetic grid 1000, an X-ray detector 1100, a power supply controller 1200, a power supply unit 1250, and an X-ray generator 1300.

The electromagnetic grid 1000 may include an electromagnetic field generating unit capable of generating a plurality of electromagnetic fields when the power is applied, and a storage unit capable of trapping metal particles integrated by the generated plurality of electromagnetic fields to form a plurality of walls. Can be. For example, the electromagnetic field generating unit may include electrodes capable of generating a plurality of electromagnetic fields. When voltage is applied to the electrodes, a plurality of electromagnetic fields are generated between the electrodes. Metal particles contained in the reservoir are integrated between the generated multiple electromagnetic fields. In other words, the integrated metal particles create a number of walls. When X-rays are applied to the electromagnetic grid 1000, some X-rays are transmitted through the plurality of walls, and some X-rays are blocked by the generated multiple walls. Accordingly, the generated plurality of walls may prevent the scattered lines generated while X-rays pass through the object placed on the electromagnetic grid 1000.

In addition, by adjusting the time the voltage is applied to the electrodes, it is possible to change the shape of the electromagnetic field generated between the electrodes. For example, by adjusting the time of the voltage applied to the electrodes, the electromagnetic field can be generated at an angle. Accordingly, metal particles can be tilted and integrated between electromagnetic fields. As such, by adjusting the voltage applied to the electrodes, the angle at which the metal particles are integrated can be easily changed. A detailed description related to the electromagnetic grid 1000 will be described later with reference to the accompanying drawings.

The X-ray detector 1100 detects an X-ray signal passing through the electromagnetic grid 1000. The X-ray detector 1100 may generate a photographed image based on the detected X-ray signal. The X-ray detector 1100 may display the generated image on a display unit (not shown). For example, the X-ray detector 1100 may be implemented by an indirect method using a photo diode or a scintillator or a direct method using a photo conductor. In addition, the X-ray detector 1100 may use various methods for detecting the X-ray signal passing through the electromagnetic grid 1000.

The power supply controller 1200 may control the power applied to the electrodes included in the electromagnetic grid 1000. For example, the power supply control unit 1200 may apply the power to the electrodes included in the electromagnetic grid 1000 so that the metal particles included in the electromagnetic grid 1000 may be vertically or inclinedly integrated. Detailed description thereof will be described later with reference to the accompanying drawings.

When it is necessary to form the grid, the power supply control unit 1200 applies power to the electrodes included in the electromagnetic grid 1000. On the other hand, when there is no need to form a grid, the power supply control unit 1200 does not apply power to the electrodes included in the electromagnetic grid 1000. Therefore, since the metal particles included in the electromagnetic grid 1000 are not integrated, the grid is not formed. If it is not necessary to form the grid, the commercial user must detach the mechanical grid from the X-ray detector 1100. On the other hand, when it is not necessary to form a grid, the power supply control unit 1200 does not apply power to the electrodes of the electromagnetic grid 1000, thereby obtaining the same effect as no grid. Thus, if there is no need to form a grid, the use of the electromagnetic grid 1000 does not require detachment of the grid.

The power supply unit 1250 provides power to the power supply control unit 1200. The provided power is applied to the electrodes included in the electromagnetic grid 1000 by the power supply controller 1200.

The X-ray generator 1300 generates X-rays and irradiates the generated X-rays toward the electromagnetic grid 1000 and the X-ray detector 1100. The irradiated X-rays pass through the electromagnetic grid 1000 to reach the X-ray detector 1100. The X-ray detector 1100 detects the reached X-rays. The X-ray detector 1100 may generate a photographed image based on the detected X-ray signal.

Electromagnetic grids are simpler in structure and simpler to manufacture than mechanical grids.

In addition, the electromagnetic grid may adjust the angle of the metal particles to be integrated by adjusting the voltage applied to the electrode. Therefore, when X-rays are irradiated from various angles, the electromagnetic grid adjusts the angle of the metal particles to be integrated, thereby preventing scattering lines generated while X-rays pass through an object placed on the electromagnetic grid 1000. have.

By using an electromagnetic grid, the X-ray apparatus can not only simplify the structure but also obtain a high quality image.

Hereinafter, the electromagnetic field generating unit will be described based on the case where the electrode is implemented, but is not limited thereto.

The electromagnetic grid 1000 may include an upper substrate 1010, a storage 1020, and a lower substrate 1030. Here, the electromagnetic field generating unit includes an upper substrate 1010 and a lower substrate 1030. A plurality of first electrodes 200, 201, 202, and 203 may be formed on the upper substrate 1010. The storage unit 1020 may trap metal particles. For example, the metal particles may be Fe, Co, Cu, Mn, Mo, Zn, Mg, Pt, Cd or compounds thereof. The reservoir 1020 may be a liquid or a gas capable of trapping fast particles. For example, the gas may be N, H, He, Si, and the like, and the liquid may be an si based solution, a polyimide solution, or the like. Alternatively, the reservoir 1020 may be a sealed box in which metal particles may be trapped. In addition, the storage unit 1020 may be formed in a variety of structures that can trap the metal particles. Second electrodes 210, 211, 212, and 213 formed to face the first electrodes 200, 201, 202, and 203 may be formed on the lower substrate 1030. In addition, in FIG. 2, the electrodes 200, 201, 202, 203, 210, 211, 212, and 213 are shown as one in a side view, but may be formed of a plurality of electrodes. A detailed shape thereof will be described with reference to FIG. 6 below.

The X-ray detector 1100 detects an X-ray signal passing through the electromagnetic grid 1000. The X-ray detector 1100 may generate a photographed image based on the detected X-ray signal. The X-ray detector 1100 may display the generated image on a display unit (not shown).

The power supply controller 1200 may control power applied to the first electrodes 200, 201, 202, and 203 and the second electrodes 210, 211, 212, and 213 included in the electromagnetic grid 1000. have. For example, the power supply controller 1200 may apply power to the first electrodes 200, 201, 202, and 203 and the second electrodes 210, 211, 212, and 213. When power is applied in this way, an electromagnetic field is formed between the electrodes 200, 201, 202, 203, 210, 211, 212, and 213, and metal particles are integrated between the formed electromagnetic fields to form a wall. In this case, the power supply control unit 1200 may apply power to the electrodes 200, 201, 202, 203, 210, 211, 212, and 213 so that the metal particles to be integrated are formed vertically or inclined. For example, when the X-rays are irradiated vertically, the power supply controller 1200 supplies power to the electrodes 200, 201, 202, 203, 210, 211, 212, and 213 so that the metal particles to be integrated are formed vertically. It can be applied simultaneously or sequentially. On the other hand, when X-rays are inclined and irradiated, the power supply control unit 1200 supplies time to the electrodes 200, 201, 202, 203, 210, 211, 212, and 213 so that the metal particles to be accumulated are inclined. You can apply with a difference. A detailed description thereof will be described later with reference to FIGS. 3 to 5. Accordingly, by changing the shape of the electromagnetic grid according to the angle at which the X-rays are irradiated, it is possible to effectively prevent the scattering lines generated while the X-rays pass through the object placed on the electromagnetic grid 1000.

Electromagnetic grids are simpler in structure and simpler to manufacture than mechanical grids.

By using an electromagnetic grid, the X-ray apparatus can not only simplify the structure but also obtain a high quality image.

FIG. 3 is a diagram for describing a case in which metal particles included in the electromagnetic grid of FIG. 2 are vertically formed.

Referring to FIG. 3, the X-ray apparatus may include an electromagnetic grid 1000, an X-ray detector 1100, and a power supply controller 1200.

The electromagnetic grid 1000 may include an upper substrate 1010, a storage 1020, and a lower substrate 1030. A plurality of first electrodes 200, 201, 202, and 203 may be formed on the upper substrate 1010. The storage unit 1020 may trap metal particles. Second electrodes 210, 211, 212, and 213 formed to face the first electrodes 200, 201, 202, and 203 may be formed on the lower substrate 1030. In this case, the first electrodes 200, 201, 202, and 203 and the second electrodes 210, 211, 212, and 213 may be formed to coincide with the central axes 300, 301, 302, and 303.

The X-ray detector 1100 may include a signal converter 1110 for converting an incident X-ray signal into an electrical signal and a readout device 1120 for reading the converted electrical signal. The X-ray detector 1100 may display the generated image on a display unit (not shown).

Hereinafter, a method of controlling the electrodes such that the power supply controller 1200 controls the metal particles included in the electromagnetic grid 1000 to be vertically formed.

The power supply controller 1200 may apply power to the first electrodes 200, 201, 202, and 203 and the second electrodes 210, 211, 212, and 213 simultaneously or sequentially. For example, the power supply controller 1200 may generate an electromagnetic field by simultaneously applying power to the first electrodes 200, 201, 202, and 203 and the second electrodes 210, 211, 212, and 213. In another example, the power supply controller 1200 applies power to the first electrode 200 and the second electrode 210, and applies power to the first electrode 201 and the second electrode 211. The electromagnetic field may be generated by applying power to the first electrode 202 and the second electrode 212, and applying power to the first electrode 203 and the second electrode 213. As such, the power supply controller 1200 may sequentially apply power to the first electrodes 200, 201, 202, and 203 and the second electrodes 210, 211, 212, and 213. When power is applied to the electrodes as described above, an electromagnetic field is generated between the first electrodes 200, 201, 202, and 203 and the second electrodes 210, 211, 212, and 213 and included in the storage 1020. Metal particles are integrated into the generated electromagnetic field. That is, the integrated metal particles form a number of walls. When X-rays are irradiated, some X-rays penetrate between the generated walls to reach the X-ray detector 1100, and some X-rays are blocked by the generated walls.

If the X-rays are irradiated vertically, the power supply control unit 1200 may apply power to the electrodes such that the metal particles included in the electromagnetic grid 1000 are vertically formed.

The electromagnetic grid can adjust the angle of the metal particles to be integrated by adjusting the voltage applied to the electrode. Therefore, when X-rays are irradiated from various angles, the electromagnetic grid may prevent scattering lines generated while X-rays pass through an object placed on the electromagnetic grid 1000 by adjusting the angle of metal particles to be integrated. .

FIG. 4 is a diagram for describing a case in which metal particles included in the electromagnetic grid of FIG. 2 are inclined.

Referring to FIG. 4, the X-ray apparatus may include an electromagnetic grid 1000, an X-ray detector 1100, and a power supply controller 1200.

The electromagnetic grid 1000 may include an upper substrate 1010, a storage 1020, and a lower substrate 1030. A plurality of first electrodes 200, 201, 202, and 203 may be formed on the upper substrate 1010. The storage unit 1020 may trap metal particles. Second electrodes 210, 211, 212, and 213 formed to face the first electrodes 200, 201, 202, and 203 may be formed on the lower substrate 1030. In this case, the first electrodes 200, 201, 202, and 203 and the second electrodes 210, 211, 212, and 213 may be formed to coincide with the central axes 300, 301, 302, and 303.

The X-ray detector 1100 may include a signal converter 1110 for converting an incident X-ray signal into an electrical signal and a readout device 1120 for reading the converted electrical signal. The X-ray detector 1100 may display the generated image on a display unit (not shown).

Hereinafter, a method of controlling the electrodes such that the power supply control unit 1200 is formed to tilt the metal particles included in the electromagnetic grid 1000 will be described.

The power supply control unit 1200 controls the electrodes such that the metal particles included in the electromagnetic grid 1000 are inclined. For example, the power supply controller 1200 applies power to the second electrode 201 of the first electrodes and the first electrode 210 of the second electrodes, and the third electrode 220 of the first electrodes. ) And power is applied to the electrode 211 located second of the second electrodes. According to the method, the power supply control unit 1200 applies power to the first electrodes 200, 201, 202, and 203 and the second electrodes 210, 211, 212, and 213. Then, an electromagnetic field is inclined between the first electrodes 200, 201, 202, and 203 and the second electrodes 210, 211, 212, and 213. Then, the metal particles are tilted and accumulated by the tilted electromagnetic field. Accordingly, inclined walls are formed in the electromagnetic grid 1000. When the X-rays are tilted and irradiated, some X-rays penetrate between the generated walls to reach the X-ray detector 1100, and some X-rays are blocked by the generated walls.

As another example, the power supply controller 1200 may apply power to the first electrode 200 of the first electrodes and the second electrode 211 of the second electrodes, and the second electrode of the first electrodes. Power is applied to the electrode 212 located third of the 201 and second electrodes. According to the method, the power supply control unit 1200 applies power to the first electrodes 200, 201, 202, and 203 and the second electrodes 210, 211, 212, and 213. Then, an electromagnetic field is inclined between the first electrodes 200, 201, 202, and 203 and the second electrodes 210, 211, 212, and 213. Then, the metal particles are tilted and accumulated by the tilted electromagnetic field. At this time, the shape of the electromagnetic field will be symmetric with respect to the vertical axis and the electromagnetic field shown in FIG. Accordingly, inclined walls are formed in the electromagnetic grid 1000. Some X-rays which are irradiated at an angle pass through the generated walls to reach the X-ray detector 1100, and some X-rays are blocked by the generated walls.

When the X-rays are inclined and irradiated, the power supply control unit 1200 may apply power to the electrodes so that the metal particles included in the electromagnetic grid 1000 are formed to be inclined.

The electromagnetic grid can adjust the angle of the metal particles to be integrated by adjusting the voltage applied to the electrode. Therefore, when X-rays are irradiated from various angles, the electromagnetic grid may prevent scattering lines generated while X-rays pass through an object placed on the electromagnetic grid 1000 by adjusting the angle of metal particles to be integrated. .

FIG. 5 is a diagram for describing a case in which metal particles included in the electromagnetic grid of FIG. 2 are inclined.

Referring to FIG. 5, the X-ray apparatus may include an electromagnetic grid 1000, an X-ray detector 1100, and a power supply controller 1200.

The electromagnetic grid 1000 may include an upper substrate 1010, a storage 1020, and a lower substrate 1030. A plurality of first electrodes 200, 201, 202, and 203 may be formed on the upper substrate 1010. The storage unit 1020 may trap metal particles. Second electrodes 210, 211, 212, and 213 formed to face the first electrodes 200, 201, 202, and 203 may be formed on the lower substrate 1030. In this case, the first electrodes 200, 201, 202, and 203 and the second electrodes 210, 211, 212, and 213 are center axes 501, 503, 505, and 507 of the first electrode and the second electrode. The central axes 500, 502, 504, 506 may be formed to be inconsistent.

The X-ray detector 1100 may include a signal converter 1110 for converting an incident X-ray signal into an electrical signal and a readout device 1120 for reading the converted electrical signal. The X-ray detector 1100 may display the generated image on a display unit (not shown).

Hereinafter, a method of controlling the electrodes such that the power supply controller 1200 controls the metal particles included in the electromagnetic grid 1000 to be vertically formed.

The power supply controller 1200 may apply power to the first electrodes 200, 201, 202, and 203 and the second electrodes 210, 211, 212, and 213 simultaneously or sequentially. For example, the power supply controller 1200 may generate an electromagnetic field by simultaneously applying power to the first electrodes 200, 201, 202, and 203 and the second electrodes 210, 211, 212, and 213. In another example, the power supply controller 1200 applies power to the first electrode 200 and the second electrode 210, and applies power to the first electrode 201 and the second electrode 211. The electromagnetic field may be generated by applying power to the first electrode 202 and the second electrode 212, and applying power to the first electrode 203 and the second electrode 213. As such, the power supply controller 1200 may sequentially apply power to the first electrodes 200, 201, 202, and 203 and the second electrodes 210, 211, 212, and 213. When power is applied to the electrodes as described above, the center axes of the first electrodes 200, 201, 202, and 203 and the second electrodes 210, 211, 212, and 213 do not coincide with the substrates 1010 and 1030. Since it is formed, an electromagnetic field is inclined between the first electrodes 200, 201, 202, and 203 and the second electrodes 210, 211, 212, and 213. Therefore, the metal particles included in the storage 1020 are integrated in the electromagnetic field generated by tilting. That is, the integrated metal particles form a number of slanted walls. When the X-rays are tilted and irradiated, some X-rays penetrate between the generated walls to reach the X-ray detector 1100, and some X-rays are blocked by the generated walls.

If the X-rays are inclined and irradiated, the power supply controller 1200 may apply power to the electrodes such that the metal particles included in the electromagnetic grid 1000 are vertically formed.

The electromagnetic grid can adjust the angle of the metal particles to be integrated by adjusting the voltage applied to the electrode. Therefore, when X-rays are irradiated from various angles, the electromagnetic grid may prevent scattering lines generated while X-rays pass through an object placed on the electromagnetic grid 1000 by adjusting the angle of metal particles to be integrated. .
