Description

Multi-energy X-ray generation control device and method

The present invention relates to a multi-energy X-ray generation control apparatus and method for controlling to generate X-rays having different energies.

In general, X-rays are used for non-destructive testing, structural and physical property testing of materials, image diagnosis, security screening, and the like in various fields such as industry, science, and medicine. Such various examinations using X-rays use the characteristic that the degree of absorption of X-rays differs according to the difference in the density of the material, transmit X-rays through the object, and then use image information derived differently according to the density difference to determine the structure of the inside of an object. This is done in a way that distinguishes the shape, etc.

It is common to acquire an image using X-rays having a single energy, but in some cases, in order to obtain a higher-quality image, an image is acquired using X-rays having different energies.

Conventionally, in order to obtain an image using such multi-energy X-rays, the electron beam propagation trajectory is fixed and the target is rotated with a motor to collide the electron beams on different targets, or multiple energy selectively using multiple cathodes. A method of generating X-rays was used. However, since this method requires mechanical devices such as a plurality of cathodes, motors, and cooling channels, the volume of the X-ray generator is large and there is a risk of mechanical defects. In order for the X-ray generator to be more widely used, it is necessary to minimize the volume and secure reliability.

In addition, the terms to be described later are terms defined in consideration of functions in an embodiment of the present invention, which may vary according to intentions or customs of users and operators. Therefore, the definition should be made based on the content throughout this specification.

1 is a block diagram of a multi-energy X-ray generation control apparatus 100 according to an embodiment of the present invention.

The multi-energy X-ray generation control apparatus 100 according to an embodiment of the present invention controls a voltage applied to a multi-energy X-ray tube including a plurality of targets respectively corresponding to a plurality of preset energies, and a filament, an anode, and an electromagnet. It may be a device.

Referring to FIG. 1 , the multi-energy X-ray generation control apparatus 100 according to an embodiment of the present invention includes a filament voltage source 110 , an anode voltage source 120 , an electromagnet voltage source 130 , and a timing controller 140 . can, but is not limited thereto. In addition, the multi-energy X-ray generation control apparatus 100 and each of the components included therein may be implemented in the form of a software module or a hardware module, or a combination of a software module and a hardware module, for example, a computer or a smart device, etc. Each of the components may be electrically connected.

The filament voltage source 110 is connected to the filament, and under the control of the timing controller 140 to be described later, the filament voltage source 110 is turned on to apply a voltage to the filament, or the filament voltage source 110 is turned off to provide a voltage to the filament may not be authorized.

The anode voltage source 120 is connected to the anode, and under the control of the timing controller 140, the anode voltage source 120 is turned on to apply a voltage to the anode, or the anode voltage source 120 is turned off to apply a voltage to the anode. may not

The electromagnet voltage source 130 is connected to the cathode and the anode of the electromagnet, and the electromagnet voltage source 130 is turned on under the control of the timing controller 140 to apply a voltage to the cathode or the anode of the electromagnet, or the electromagnet voltage source 130 is turned It can be turned off so that no voltage is applied to the electromagnet.

The timing control unit 140 determines the voltage application timing of the filament voltage source 110 , the anode voltage source 120 , and the electromagnet voltage source 130 so that the electron beam collides with any one target corresponding to the energy to be emitted from among the plurality of targets to generate X-rays. can be controlled.

In more detail, the timing controller 140 may control the filament voltage source 110 and the anode voltage source 120 to be turned on or off so that an electron beam is formed.

Here, the electron beam (or electrons) may have a predetermined level of energy according to an applied voltage. For example, as the magnitude of the applied voltage increases, the electron beam may have high energy. Accordingly, the energy of the electron beam may be adjusted by adjusting the applied voltage.

On the other hand, in general, the traveling direction of the electron beam may have a straight shape. The multi-energy X-ray generation control apparatus 100 according to an embodiment is perpendicular to the traveling direction of the electron beam, that is, above and below the traveling direction of the electron beam. The electron beam direction can be adjusted by using a phenomenon in which the traveling direction of an electron beam passing through a space between a plurality of electromagnets spaced apart to face each other while being spaced apart by a predetermined distance is bent by a predetermined angle.

Specifically, a magnetic field may be formed between the plurality of electromagnets (which may be low-carbon steel electromagnets), and the propagation direction of the electron beam passing through the space between the plurality of electromagnets may be bent by a predetermined angle by the magnetic field thus formed. . That is, by the magnetic field of the electromagnet, the electron beam (or electrons constituting the electron beam) may receive a Lorentz force and may be bent in a traveling direction by a predetermined angle.

In this case, the degree of bending may be different depending on the energy of the electron beam. For example, as the energy of the electron beam is low, it may be bent relatively more compared to an electron beam having high energy, and as the energy of the electron beam is high, it may be bent relatively little compared to an electron beam having low energy.

In other words, since the energy of the electron beam increases as the applied voltage increases as described above, by adjusting the magnitude of the applied voltage, the energy of the electron beam becomes a set value and the magnetic field is formed by the electromagnet so that the direction of the electron beam is changed. It can be controlled to be bent at a specified angle.

Accordingly, the timing controller 140 may control the electromagnet voltage source 130 to be turned on or off so that the traveling direction of the electron beam is bent at a predetermined angle.

For example, the timing controller 140 turns on each of the filament voltage source 110 , the anode voltage source 120 and the electromagnet voltage source 130 to control the voltage to be applied for a predetermined time, or the filament voltage source 110 , the anode voltage source By turning off each of the 120 and the electromagnet voltage source 130, it is possible to control the voltage not to be applied.

At this time, when controlling the voltage applied from the electromagnet voltage source 130 , the timing controller 140 turns on the electromagnet voltage source 130 according to the direction of the electron beam to be adjusted to apply a voltage to the cathode of the electromagnet or the anode of the electromagnet. Alternatively, the electromagnet voltage source 130 may be turned off to control so that no voltage is applied to the electromagnet.

As will be described later, each of the plurality of targets is made of a different material (or element) for generation of multi-energy X-rays and may be positioned to have a predetermined distance interval, and based on the control of the electron beam traveling direction, at least one of the plurality of targets The electron beam may impinge on one target part, ie the desired target. At this time, since the energy bands that can be generated when the electron beam collides with each of the different materials may be different from each other, by controlling the traveling direction of the electron beam so that the electron beam collides with each of the plurality of targets, different energy from each of the plurality of targets X-rays having

As an embodiment, the plurality of targets may respectively correspond to first energy, second energy, and third energy having different energy bands. When the collision is controlled to generate X-rays, the filament voltage source 110 is turned on, and while the filament voltage source 110 is turned on, the electromagnet voltage source 130 is turned on so that a voltage is applied to the anode of the electromagnet, and then the anode voltage source 120 can be controlled to be turned on.

In addition, the timing controller 140 turns on the filament voltage source 110 while turning off the electromagnet voltage source 130 when the electron beam collides with the target corresponding to the second energy to generate X-rays, and turns on the filament voltage source 110 . ) may be controlled to be turned on while the anode voltage source 120 is turned on.

In addition, the timing controller 140 turns on the filament voltage source 110 when the electron beam collides with the target corresponding to the third energy to generate X-rays, and turns on the filament voltage source 110 to the cathode of the electromagnet while the voltage source 110 is turned on. After the electromagnet voltage source 130 is turned on so that a voltage is applied, the anode voltage source 120 may be controlled to be turned on.

At this time, when the plurality of targets include different materials and include a first target corresponding to the first energy, a second target corresponding to the second energy, and a third target corresponding to the third energy, the timing controller ( 140) may control the voltage to be applied from the electromagnet voltage source 130 to the anode of the electromagnet so that the upwardly curved electron beam collides with the first target to generate the first X-ray as the direction of the electron beam is bent upward.

In addition, the timing controller 140 may control so that a voltage is not applied from the electromagnet voltage source 130 so that, as the electron beam is generated in a straight line without being bent, the electron beam generated in a straight line collides with the second target to generate the second X-ray. have.

In addition, the timing controller 140 may control the voltage to be applied to the cathode of the electromagnet from the electromagnet voltage source 130 so that the downwardly curved electron beam collides with the third target and generates third X-rays as the electron beam is bent downward. .

Here, the first X-ray, the second X-ray, and the third X-ray generated by the timing controller 140 controlling the electromagnet voltage source 130 may have different energy and transmittance.

In more detail, since energy and transmittance are proportional to each other, when the energy of the first X-ray is lower than that of the second X-ray and the third X-ray, the transmittance is also smaller than that of the first X-ray and the second X-ray. can be used to take pictures. Also, when the second X-ray has greater energy than the first and third X-rays, transmittance is also greater than that of the first and third X-rays, so that the third X-ray may be used to photograph the head (or head).

On the other hand, the multi-energy X-ray generation control apparatus 100 according to an embodiment determines the number of a plurality of targets made of a material different from the number of electron beams (or energy levels) formed by the multi-energy X-ray generation control apparatus 100 . X-rays may be generated as much as the multiplied value.

For example, when the number of electron beams (or energy levels) formed by the multi-energy X-ray generation control apparatus 100 is three and the number of a plurality of targets made of different materials is three, a total of nine X-rays are generated. can be

On the other hand, the timing control unit 140 is filament voltage source 110, the anode voltage source 120, and the electromagnet voltage source 130 in consideration of the time when voltage is applied to the filament, the anode and the electromagnet in each filament voltage source 110, the anode voltage source ( 120) and the voltage applied from the electromagnet voltage source 130 may be controlled.

That is, the timing control unit 140 after transmitting a signal for controlling the voltage to the filament voltage source 110, the anode voltage source 120 and the electromagnet voltage source 130, actually the filament voltage source 110, the anode voltage source 120 and the electromagnet The voltage applied from the filament voltage source 110 , the anode voltage source 120 , and the electromagnet voltage source 130 may be controlled in consideration of the time in which the voltage applied by the voltage source 130 is reflected.

Furthermore, the timing controller 140 may adjust the voltage intensity applied by the filament voltage source 110, the anode voltage source 120, and the electromagnet voltage source 130 according to the direction of the electron beam to be formed or the electron beam to be adjusted, for example, For example, the intensity of the voltage supplied to the electromagnet may be adjusted so that the electron beams do not overlap in consideration of the size of the reach of the electron beams between the electron beam energies.

Meanwhile, the X-rays having different energies generated by the multi-energy X-ray generation control apparatus 100 according to an embodiment are integrally considered based on the emission to the outside, so that a multi-energy X-ray image may be finally generated. Integration of X-rays having different energies is easy for a person skilled in the art, and detailed descriptions thereof will be omitted.

2 is a block diagram of a multi-energy X-ray generation control apparatus according to another embodiment of the present invention.

Referring to FIG. 2 , the multi-energy X-ray generation control apparatus 100 according to another embodiment of the present invention includes a filament voltage source 110 , an anode voltage source 120 , an electromagnet voltage source 130 , and a timing controller 140 in addition to the grid It may further include a voltage source 150, the grid voltage source 150 is connected to the grid (focusing-cup), under the control of the timing controller 140, the grid voltage source 150 is turned on to apply a voltage to the grid Alternatively, the grid voltage source 150 may be turned off so that no voltage is applied to the grid.

Hereinafter, the voltage control by the timing controller 140 will be described in detail with reference to FIGS. 3 to 6 .

3 is a diagram for explaining that electron beams having different energies are generated according to an embodiment, and FIG. 4 is a voltage timing diagram of a multi-energy X-ray generation control apparatus for controlling an electron beam in an anode direction according to an embodiment. 5 is a voltage timing diagram of a multi-energy X-ray generation control apparatus for controlling an electron beam in a straight direction according to an embodiment, and FIG. 6 is a multi-energy X-ray generation for controlling an electron beam in a cathode direction according to an embodiment is the voltage timing diagram of the control unit,

First, referring to FIG. 3 , when the timing control unit 140 controls the filament voltage source 110 and the anode voltage source 120 to be turned on so that a voltage is applied to each of the filament 300 and the anode 310, the filament (cathode) ) 300 , electrons may be emitted to form an electron beam, and based on the electrons emitted from the filament 103 , the electron beam may proceed in an accelerated manner to the anode (anode) 305 .

In addition, when the timing controller 140 controls the electromagnet voltage source 130 to be turned on so that a voltage is applied to the electromagnet 307, electrons are emitted from the filament (cathode) 300 to form an electron beam (eg, a first electron beam ( 310), the second electron beam 320, and the third electron beam 330) are bent at different angles to different targets (eg, the first target 315, the second target 325, the third target 335). You can see that they collide with each other.

Specifically, each of the first electron beam 310 , the second electron beam 320 , and the third electron beam 330 may represent an example in which different predetermined voltages are applied to the cathode at once.

For example, the first electron beam 310 may be an electron beam generated when a voltage of 40 kV (first energy) is applied, and the second electron beam 320 is generated when a voltage of 60 kV (second energy) is applied. The third electron beam 330 may be an electron beam generated when a voltage of 50 kV (third energy) is applied.

Each of the first target 315 , the second target 325 , and the third target 335 may be formed of a different material. For example, the first target 315 , the second target 325 , and the third target 335 may be at least one of tungsten (W), molybdenum (Mo), rhodium (Rh), and tantalum (Ta). However, the type of material constituting the target is not limited to the above, and may be composed of various materials (eg, chromium, copper) with a melting point higher than a predetermined value (or a predetermined value) to withstand the collision of the electron beam. .

In this case, each of the first target 315 , the second target 325 , and the third target 335 may correspond to a preset energy region, and as an embodiment, the first target 315 corresponds to the low energy region. In this case, the first target 315 may be at least one of rhodium (Rh) and tantalum (Ta), and when the second target 325 corresponds to a high energy region, the second target 325 is tungsten ( W), and when the third target 335 corresponds to the medium energy region, the third target 335 may be molybdenum (Mo), but the material of the target corresponding to the preset energy region is the above-mentioned material. The bar is not limited thereto, and a material different from the above example may be used as the material type of the target corresponding to the preset energy region according to circumstances.

As an embodiment, referring to FIG. 4 , the timing controller 140 generates the first X-rays generated by the collision of the electron beam with the first target 315 , the filament voltage source 110 , the anode voltage source 120 , and the electromagnet The voltage application timing in the voltage source 130 may be controlled.

In more detail, the timing controller 140 turns on the filament voltage source 110 to form an electron beam so that the electron beam is formed, and the filament voltage source 110 (Filament PS) is turned on while the voltage is applied to the anode of the electromagnet so that a voltage is applied. After the voltage source 130 (Electromagnet PS) is turned on, the anode voltage source 120 (Anode PS) may be turned on so that the formed electron beam is accelerated and collides with the target.

In this case, when the timing controller 140 turns on the electromagnet voltage source 130 (Electromagnet PS) so that a voltage is applied to the anode of the electromagnet, the electron beam may be bent upward.

Therefore, when the timing controller 140 controls the voltage application timing from the filament voltage source 110 , the anode voltage source 120 , and the electromagnet voltage source 130 , the electron beam is bent upward and collides with the first target 315 . 1 X-rays may be generated.

As another embodiment, referring to FIG. 5 , the timing controller 140 generates a second X-ray generated by collision of an electron beam on a second target 325 , a filament voltage source 110 , an anode voltage source 120 , and an electromagnet The voltage application timing in the voltage source 130 may be controlled.

In more detail, the timing controller 140 turns on the filament voltage source 110 to form an electron beam so that an electron beam is formed, and the electromagnet voltage source 130 (Electromagnet PS) is turned so that the direction of the formed electron beam is applied in a straight direction. The anode voltage source 120 (Anode PS) may be turned on so that an electron beam formed while the filament voltage source 110 (Filament PS) is turned on is accelerated and collides with the target while being turned off.

In this case, when the timing controller 140 turns off the electromagnet voltage source 130 (Electromagnet PS), the electron beam may be generated in a straight direction.

Therefore, when the timing controller 140 controls the voltage application timing in the filament voltage source 110 , the anode voltage source 120 , and the electromagnet voltage source 130 , the electron beam is straight as no voltage is applied to the electromagnet 307 . The second X-ray may be generated by colliding with the second target 325 in the form of .

As another embodiment, referring to FIG. 6 , the timing controller 140 generates a third X-ray generated by colliding an electron beam with a third target 335 , a filament voltage source 110 , an anode voltage source 120 , and The voltage application timing in the electromagnet voltage source 130 may be controlled.

In more detail, the timing controller 140 turns on the filament voltage source 110 to form an electron beam to form an electron beam, and the filament voltage source 110 (Filament PS) is turned on so that a voltage is applied to the cathode of the electromagnet. After the voltage source 130 (Electromagnet PS) is turned on, the anode voltage source 120 (Anode PS) may be turned on so that the formed electron beam is accelerated and collides with the target.

In this case, when the timing controller 140 turns on the electromagnet voltage source 130 (Electromagnet PS) so that a voltage is applied to the cathode of the electromagnet, the electron beam may be bent downward.

Therefore, when the timing controller 140 controls the voltage application timing from the filament voltage source 110 , the anode voltage source 120 and the electromagnet voltage source 130 , the electron beam is bent downward and collides with the third target 335 . 3 X-rays may be generated.

In this case, the first X-ray, the second X-ray, and the third X-ray generated by the multi-energy X-ray generation control apparatus 100 according to an embodiment may have different energies and transmittances.

Accordingly, the multi-energy X-ray generation control apparatus 100 according to an embodiment is formed by controlling the voltage application timing in the filament voltage source 110 , the anode voltage source 120 , and the electromagnet voltage source 130 in the timing controller 140 . The direction of the electron beam is adjusted, and as the electron beam of the adjusted direction collides with one of a plurality of targets made of different materials, X-rays having different energies may be generated.

For example, when the first X-ray has lower energy than the second X-ray and the third X-ray, transmittance is also smaller than the first X-ray and the second X-ray, so that the first X-ray can be used to photograph a hand, and the second X-ray When the energy is greater than that of the first and third X-rays, transmittance is also greater than that of the first and third X-rays, so that the third X-ray can be used to photograph the head (or head).

7 is an exemplary flowchart of a method for controlling generation of multi-energy X-rays according to an embodiment. The multi-energy X-ray generation control method illustrated in FIG. 7 may be performed by the multi-energy X-ray generation control apparatus 100 illustrated in FIG. 1 . In addition, the multi-energy X-ray generation control method illustrated in FIG. 7 is merely exemplary.

Referring to FIG. 7 , the timing controller 140 applies a voltage to each of a filament, an anode, and an electromagnet so that an electron beam collides with at least one target among a plurality of targets corresponding to a plurality of preset energies to generate X-rays. The voltage application timing in the voltage source 110 , the anode voltage source 120 , and the electromagnet voltage source 130 may be controlled (step S100 ).

In more detail, the timing controller 140 controls the filament voltage source 110 and the anode voltage source 120 to be turned on or off so that an electron beam is formed, and the electromagnet voltage source 130 is turned on so that the traveling direction of the electron beam is bent at a predetermined angle. Alternatively, it can be controlled to be turned off.

Then, based on the control of the timing controller 140 in step S100, each of the filament voltage source 110, the anode voltage source 120 and the electromagnet voltage source 130 may be turned on or off (step S200).

As described above, the multi-energy X-ray generation control apparatus and method according to an embodiment of the present invention controls an electron beam using a plurality of targets, filaments, anodes, and electromagnets respectively corresponding to a plurality of preset energies to control the multi-energy By generating X-rays, the volume can be minimized and reliability of bonding can be secured.

In addition, by controlling the voltage application timing in the filament voltage source and the anode voltage source to form an electron beam, and controlling the voltage application timing in the electromagnet voltage source so that the direction of the formed electron beam is adjusted, any one corresponding to the energy to be emitted from among the plurality of targets X-rays can be generated by causing an electron beam to collide with a target of
