Description

≪ Desc / Clms Page number 1 > METHOD AND APPARATUS FOR ACCELERATING PARTICLE BASED ON LASER < RTI ID =

Cancer incidence and cancer-related deaths are continuously increasing in Korea. Despite the rapid growth of medical diagnosis and treatment technology in recent years, the factors that determine the survival rate difference of cancer are early detection. Current diagnostic methods are only able to diagnose cancer after a certain degree of MASS is formed by the proliferation of cancer cells. Therefore, metastasis is already occurring at the time of cancer diagnosis, so that it often happens to miss the appropriate treatment period and lead to death.

Like reference numerals are used for like elements in describing each drawing.

The terms first, second, etc. may be used to describe various components, but the components should not be limited by the terms. The terms are used only for the purpose of distinguishing one component from another. For example, without departing from the scope of the present invention, the first component may be referred to as a second component, and similarly, the second component may also be referred to as a first component. And / or < / RTI > includes any combination of a plurality of related listed items or any of a plurality of related listed items.

It is to be understood that when an element is referred to as being "connected" or "connected" to another element, it may be directly connected or connected to the other element, . On the other hand, when an element is referred to as being "directly connected" or "directly connected" to another element, it should be understood that there are no other elements in between.

The terminology used in this application is used only to describe a specific embodiment and is not intended to limit the invention. The singular expressions include plural expressions unless the context clearly dictates otherwise. In the present application, the terms "comprises" or "having" and the like are used to specify that there is a feature, a number, a step, an operation, an element, a component or a combination thereof described in the specification, But do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, or combinations thereof.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Hereinafter, the same reference numerals will be used for the same constituent elements in the drawings, and redundant explanations for the same constituent elements will be omitted.

Hereinafter, embodiments of the present invention relate to a method of accelerating a proton or an inteface using a laser beam. Hereinafter, the term "particle" is used to denote a proton or an intruder that is accelerated by a laser beam. The particles must be in a high energy state in order for the particles to reach the tumor site in the body. By using the high energy laser ion acceleration method according to the embodiment of the present invention, it is possible to reach the tumor region of the human body in a high energy state.

The first laser beam can be focused on the thin film target to generate and accelerate the particles to generate the first accelerated particles. Further, it is possible to generate second accelerating particles having additional energy by irradiating the first accelerating particles with the second laser beam. These high-energy second accelerating particles can easily penetrate the tumor site. Hereinafter, a method for accelerating particles based on a plurality of laser beams in an embodiment of the present invention will be described.

Focusing the picosecond ~ femtosecond laser light on the thin film can accelerate particles such as protons or carbon ions. The particle acceleration model may be, for example, a Target normal sheath acceleration (TNSA) model or a radiation pressure model.

First, the target normal sheath acceleration (TNSA) model can be used when the laser intensity is less than 1020 W / cm 2. When the laser beam is incident on the thin film, electrons in the thin film can be accelerated to fall off the rear surface of the thin film and instantly exist in the form of an electron clouding. At that time, protons or cations inside the thin film are left, and a very large electric field of 1012 V / cm or more can be formed between the electron cloud and the cations on the backside. By this electric field, the cation can be accelerated toward the electron cloud. When the energy of the electric field reaches 200 MeV, the electric field allows the cation to reach deep tumors 15 cm or more in the body. The ion is accelerated in the direction perpendicular to the surface of the target film irrespective of the angle of incidence of the thin film target, so it is called the TNSA model.

Next, ions can be accelerated using a radiation pressure model. When the laser intensity is above 1021 W / cm2, the ions accelerate in the direction of the laser beam differently from the TNSA model. The radial pressure model is a model according to the electromagnetic Lorentz force. Lorentz force is the force that a charged object receives in an electromagnetic field. The object receives the force of qE in the electric field and receives the force of the magnetic field qv x B. Where E is the electric field, B is the magnetic field, q is the charge of the particle, v is the speed of the particle, and x is the outer product It means.

That is, the principle of acceleration of the particles can be changed according to the intensity of the laser. The particles subjected to the radial pressure model have a high acceleration energy and the energy of the particles applied to the TNSA model may be smaller than the energy applied to the radial pressure model. In a conventional light pressure model, such as the TSNA model or the radiation pressure model, the light pressure applied to the particles was only once.

In the particle accelerating method based on a plurality of laser beams according to an embodiment of the present invention, it is possible to generate particles of higher energy than conventionally by applying various light pressures in accelerating particles. Hereinafter, a specific laser-based particle acceleration method according to an embodiment of the present invention will be described.

1 is a conceptual diagram illustrating a particle accelerated laser system according to an embodiment of the present invention.

Referring to FIG. 1, unlike a conventional method of accelerating particles using a single radiation pressure, additional light pressure may be applied to the particles to accelerate the particles. That is, in the particle-accelerated laser system according to the embodiment of the present invention, particles having a larger energy than the conventional one can be generated by two light pressures, and high-energy particles can be generated, thereby enabling treatment of tumors located deep within the human body .

The ion accelerated laser system may include a laser oscillator 100, a thin film 110, a beam splitter 120, first to fourth reflectors 121 to 124, and an off axis reflector 130.

The laser oscillator 100 may be implemented to generate a laser of a femtosecond to a picosecond.

The thin film 110 may be implemented to generate particles when light pressure is applied.

The beam splitter 120 separates the laser beam 140 emitted from the laser oscillator 100 into a first laser beam 150 and a second laser beam 200. The separated first laser beam 150 may be transmitted to the first reflector 121 and the second laser beam 200 may be transmitted to the second reflector 122.

The first laser beam 150 transmitted to the first reflector 121 may be reflected and transmitted to the non-retroreflective mirror 130 and may be focused and transmitted to the thin film 110. The particles 180 can be generated and accelerated by the first laser beam 150 transmitted to the thin film 110. [ This will be described later in detail.

The second laser beam 200 transmitted to the second reflector 122 may be reflected by the third reflector 123 and the fourth reflector 124 and may be transmitted to the thin film 110. The second laser beam 200 may additionally apply a second light pressure to the particles 180 accelerated by the first light pressure by the first laser beam 150. This allows the particles 180 to receive additional acceleration energy.

2 is a conceptual diagram illustrating a method of applying light pressure to particles based on a first laser beam according to an embodiment of the present invention.

Referring to FIG. 2, the laser beam 140 generated from the laser oscillator 100 may be divided into two beams in the beam splitter 120. The first laser beam 150 separated from the beam splitter 120 can enter the retroreflecting mirror 130 by changing the traveling path in the first reflecting mirror 121.

The non-shrinking reflector 130 may focus 160 the first laser beam 150 such that the thin film 110 is at a focal distance. Particles 170 such as protons or intrusions, heavy ions, etc., can be accelerated by the principle of laser-matter interaction (laser light pressure model) or TNSA model of the focused laser beam and thin film.

This is referred to as acceleration by radiation pressure, and the accelerated particle by the first light pressure can be expressed by the term first acceleration particle. The first accelerating particles may proceed toward the location 190 of the human tumor. The present invention may use additional optical systems in embodiments to apply additional light pressure to the first accelerating particles such that higher energy particles are directed toward the tumor location 190. [

The laser beam 200 partially transmitted through the beam splitter 120 during the time when the laser beam 150 reflected from the beam splitter 120 is acting on the thin film 110 is applied to the second reflector 122, Lt; / RTI > The laser beam directed toward the second reflector 122 may be expressed by the term second laser beam 200. [

3 is a conceptual diagram illustrating the progress of the second laser beam according to the embodiment of the present invention.

Referring to FIG. 3, while the first laser beam reflected by the beam splitter is incident on the thin film to generate first accelerated particles accelerated by the first light pressure generated, the laser beam 200 partially transmitted through the beam splitter Can be expressed in terms of a second laser beam.

The second laser beam can reach the thin film sequentially through the second reflector 122, the third reflector 123, and the fourth reflector 124 in sequence. The second reflector 122 may be disposed at a position for transmitting the reflected second laser beam to the third reflector 123. The third reflector 123 may be disposed at a position for transmitting the reflected second laser beam to the fourth reflector 124. The fourth mirror 124 may be implemented in a position for transmitting the reflected second laser beam to the thin film.

The arrangement of the mirrors may be a variety of other arrangements for irradiating the second laser beam with particles with a time difference from the first laser beam.

At this time, the thin film may be in a state where the material structure has already been disassembled by the first laser beam. Accordingly, the second laser beam can generate the second accelerating particles 170 by advancing the target position without resistance and adding additional energy to the first accelerating particles. The second accelerating particle can reach the tumor location 190 with a high energy state.

4 is a conceptual diagram illustrating a method of applying additional light pressure to ions according to an embodiment of the present invention.

Referring to FIG. 4, the second laser beam may apply an additional light pressure to the first accelerating particles accelerated by the first light pressure. Accelerated particles due to additional light pressure can be expressed by the term second accelerator particle. The particles receiving the first light pressure and the second light pressure may be protons or intumescent particles. The particles are first generated and accelerated in the target thin film by the first light pressure, and after a certain time, the second light pressure is applied to the particles moving through the second laser beam to obtain additional energy. The time difference between the first light pressure and the second light pressure can be adjusted by adjusting the length of the optical path of the second laser beam. According to the present invention, since the energy of the particles generated by the first laser beam does not exceed the speed of light, the first accelerating particles can be influenced by the second light pressure by the second laser beam. That is, the acceleration energy due to the first light pressure by the first laser beam and the acceleration energy due to the second light pressure of the second laser beam are added to the particles to obtain high energy particles.

The particle acceleration method using a plurality of laser beams as described above can perform particle acceleration by three or more laser beams instead of two laser beams as an example. The number of laser beams used to accelerate the particles may vary depending on the amount of energy required for the particles.

5 is a conceptual diagram illustrating an apparatus for accelerating particles based on a laser beam according to an embodiment of the present invention.

In Figure 5, a method for accelerating particles based on three beams is posted. In FIG. 5, for convenience of explanation, a method of accelerating particles based on three laser beams may be published, but particles may be accelerated by laser beams of three or more laser beams.

Referring to FIG. 5, an apparatus for accelerating particles based on a laser beam may include a first laser beam reflector, a second laser beam reflector, and a third laser beam reflector.

The first laser beam reflector may reflect the first laser beam to generate particles as the first accelerated particles by performing the operation as described above with reference to FIG.

Specifically, the laser oscillator 100 may be implemented to generate a laser of a femtosecond to a picosecond. The beam splitter 120 splits the laser beam 140 emitted from the laser oscillator 100 into a first laser beam 150 and a second laser beam 140. The laser beam 140 emitted from the laser oscillator 100 is incident on the first laser beam 150, The laser beam 200 can be separated. The separated first laser beam 150 is transmitted to the first reflector 121 and the first laser beam 150 transmitted to the first reflector 121 is reflected and transmitted to the non- (Not shown). The first accelerated particle can be generated by the first laser beam 150 transmitted to the thin film 110.

In addition, the second laser beam reflector may reflect the laser beam through the operation as described above with reference to FIGS. 3 and 4 to generate particles as second accelerated particles.

The second laser beam 200 can reach the thin film 110 through the second reflector 122, the third reflector 123 and the fourth reflector 124 in order. The second laser beam 200 arriving at the thin film 110 can generate energy by applying energy to the first accelerating particles.

Also, according to the embodiment of the present invention, a second beam splitter 135 may be additionally provided between the second reflector 122 and the third reflector 123 to implement a third laser beam reflector. The second beam splitter 135 may generate the third laser beam 300 based on the second laser beam 200. The third laser beam 300 reaches the thin film 110 through the fifth mirror 125, the sixth mirror 126, and the seventh mirror 127 in the same manner as the second laser beam reflector, Additional energy can be applied to produce third accelerated particles.

In this way, an apparatus for accelerating particles based on a laser beam according to an embodiment of the present invention can implement three or more laser beam reflectors by implementing an additional laser beam reflector through beam separation.

6 is a conceptual diagram illustrating an apparatus for accelerating particles based on a laser beam according to an embodiment of the present invention.

Referring to FIG. 6, the laser particle accelerator may include a treatment depth determiner 600, a driving laser determiner 620, a laser beam generator 640, and a processor 650. Each constituent part of the laser particle accelerator is classified as a functional part so that one constituent part can be embodied as a plurality of constituent parts or a plurality of constituent parts can be embodied as one constituent part.

The treatment depth determination unit 600 can analyze the position of the tumor to determine information about the depth to which the laser should reach. According to embodiments of the present invention, the energy to be applied to the particles can be determined differently depending on the depth of the tumor.

The driving laser crystal portion 620 can determine the number of laser reflecting portions to be driven according to the laser reaching depth determined by the treating depth determining portion. For example, if the location of the tumor is not relatively deep, the number of laser reflections where the laser beam is reflected can be determined with a relatively small number. When the position of the tumor is relatively deep, the number of laser reflection parts in which the laser beam is reflected can be determined to be a relatively large number. By using this method, the amount of energy applied to the particle can be determined differently depending on the position to which the laser beam should reach.

The laser beam generator 640 may generate a laser beam according to the number of laser reflectors determined based on the driving laser determiner 620.

The processor 650 may be implemented to control the treatment depth determiner 600, the driving laser determiner 620, and the laser beam generator 640.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims. It will be possible.
