微波热疗辐射器和微波热疗装置 Microwave hyperthermia and microwave hyperthermia equipment radiators

技术领域 Technical Field

[0001] 本发明涉及微波热疗技术,更具体地说,涉及微波热疗辐射器和微波热疗装置。 [0001] The present invention relates to a microwave thermotherapy technology, and more particularly, to microwave radiation and hyperthermia microwave hyperthermia devices.

背景技术 Background

[0002] 生物体受到微波的照射会产生热效应,通过高温可直接杀死肿瘤细胞。 [0002] organisms by microwave radiation can produce thermal effects, high temperature can directly kill tumor cells. 因此,通常采用微波热疗技术治疗肿瘤。 Therefore, usually microwave hyperthermia treatment of tumors. 微波照射人体之所以产生微波生物效应,是因为人体各种组织都有固有频率,当微波频率与某组织的固有频率相同时,该组织就产生谐振吸收。 Microwave irradiation microwave biological effects are the result of the body, because the human body has a natural frequency of a variety of organizations, when the microwave frequency and the natural frequency of an organization is the same, the organization produces a resonant absorption. 当该组织吸收的能量超过某一减阀值时,就会引起生物效应。 When the energy absorbed by the tissue above a certain threshold reduction, it can cause biological effects. 微波热疗效果好的主要原因如下: Microwave hyperthermia effect of good reasons:

[0003] (I)微波热疗是微波照射到病变部位后,病变组织吸收微波能自身产生热量,因此病变组织比其他热敷升温快,并且温度分布均匀。 [0003] (I) is a microwave irradiation of microwave hyperthermia after lesion, lesions themselves absorb microwave energy to generate heat, thus heating up the diseased tissue faster than other heat, and the temperature distribution.

[0004] (2)微波有选择加热的特性:人体的各种组织的介电常数是不相同的,因此各种组织吸收微波的能力也不相同。 [0004] (2) selective microwave heating properties: dielectric constant of the various tissues of the human body is not the same, and therefore the ability to absorb microwaves various tissues is not the same. 吸收微波能力强的组织升温就快,吸收能弱的升温就慢。 Ability of the organization to absorb the microwave to heat up soon, weak absorption can slow warming. 病变组织往往比正常组织吸收微波能力强,升温快,从而达到了选择治疗之目的。 Diseased tissue than in normal tissue often strong microwave absorption capacity, fast heating, so as to achieve the purpose of the treatment of choice. 其他热疗方法,就没有这个特性。 Other hyperthermia method, you do not have this feature.

[0005] (3)微波热疗可以确诊病变部位,而其他热敷治疗方法则不能:若病变部位是炎症,病变部位的微血管因被发炎组织的压迫而变窄,造成血液循环不畅,当用微波照射病变部位时,难免同时照射到与病变部位相毗邻的健康组织,也就是病变组织与健康组织同时被微波加热。 [0005] (3) microwave hyperthermia can be diagnosed lesions, and other heat treatments can not: If the lesion is inflammation, microvascular lesion is inflamed tissue due to the oppression and narrow, causing poor blood circulation, when used microwave irradiation lesion, inevitably simultaneously irradiated to a lesion adjacent healthy tissue, which is the diseased tissue and healthy tissue while being heated by microwave. 对于健康组织而言,吸收微波产生的热量大部分被循环的血液带走通过皮肤散发到体外;对于病变组织,因血液循环不畅而急剧升温。 For healthy tissue, the heat circulating blood away most of the absorption of the microwave generation distributed to the body through the skin; for diseased tissue, due to poor blood circulation and rapid warming. 当局部病变组织温度升到38 0C _39°C时,患部就有疼痛感了。 When the local lesions temperature rose to 38 0C _39 ° C when there is pain of the affected area. 疼痛部位就是病变部位,从而准确确定了病变位置,这一特点对提高疗效,缩短疗程大有裨益。 Pain is part of the lesion, to accurately determine the location of the lesion, a feature to improve the efficacy, shorten the course of great benefit.

[0006] 热疗不仅在治疗恶性肿瘤中起重大作用,而且在治疗许多良性疾病中效果也非常显著,在临床应用中显示出了巨大的发展潜力和广阔的应用前景,使广大患者受益。 [0006] Hyperthermia not only played a major role in the treatment of malignant tumors, and in the treatment of many benign diseases effect is very significant, showing great clinical application potential and broad prospects, the majority of patients benefit.

[0007] 但是目前的微波热疗过程中,除了照射到病变部位之外,还会照射到与病变部位相毗邻的健康组织,造成对正常组织的损伤,另外由于微波能量汇聚的程度较低,使得热疗效果也不好,加热时间较长,这是不希望看到的结果,因此,需要一种能够减少正常组织损伤、提高热疗效率的微波热疗技术。 [0007] However, the current microwave hyperthermia process, in addition to the lesion is irradiated outside, and also irradiated lesion adjacent healthy tissue, causing damage to normal tissue, additional microwave energy due to the low degree of aggregation, hyperthermia effect is not so good, long heating time, this is the result not want to see, therefore, we needed a way to reduce normal tissue damage, improve the efficiency of microwave hyperthermia hyperthermia techniques.

[0028] 超材料是一种以人造微结构2为基本单元并以特定方式进行空间排布、具有特殊电磁响应的新型材料,包括人造微结构2和供人造微结构附着的基板I。 [0028] In metamaterial is a synthetic microstructures 2 as the basic unit in a particular manner and spatial arrangement, with special electromagnetic response of new materials, including synthetic microstructures adhered to a substrate for artificial microstructure 2 and I. 人造微结构2为由至少一根金属丝组成的平面结构或立体结构,多个人造微结构2在基板I上阵列排布,每个人造微结构2以及其所附着的基板I所占部分即为一个超材料单元。 Plane structure or three-dimensional structure by at least 2 artificial microstructure consisting of a metal wire, a plurality of artificial microstructure 2 on the substrate I arrayed, each artificial microstructure 2 and the substrate it is attached I share part of that is a metamaterial unit. 基板I可为任何与人造微结构2不同的材料,这两种材料的叠加使每个超材料单元产生一个等效介电常数与磁导率,这两个物理参数分别对应了超材料单元的电场响应与磁场响应。 I can be any substrate and artificial microstructure 2 different materials, superposition of these two materials so that each metamaterial unit generates an effective permittivity and permeability, two physical parameters correspond to the metamaterial unit in response to an electric field and magnetic field responses. 超材料对电磁响应的特征是由人造微结构2的特征所决定,而人造微结构2的电磁响应很大程度上取决于其金属丝的图案所具有的拓扑特征和其几何尺寸。 Metamaterial electromagnetic response characteristic is determined by the man-made micro-structural features of two, and man-made electromagnetic micro structure 2 in response to a large extent depend on the topological features of its wire and the pattern has its geometry. 根据上述原理设计超材料空间中排列的每个人造微结构2的拓扑图形和几何尺寸,就可对超材料中每一点的电磁参数进行设置。 According to the principles of the design of each artificial metamaterial micro-structural space arrangement and geometry topology graph 2, it can point to each metamaterial electromagnetic parameters.

[0029] 图I是依据本发明一优选实施例的微波热疗辐射器100的结构示意图,该微波热疗辐射器包括辐射器本体20、安装在辐射器本体20上的超材料面板10。 [0029] Figure I is a schematic structural view of a microwave thermotherapy radiator according to the present invention, a preferred embodiment 100 of the microwave hyperthermia radiator 20 includes a radiator body, mounted on the body 20 of the radiator 10 metamaterial panel. 作为公知常识我们可知,电磁波的折射率与-^εχμ成正比关系,当一束电磁波由一种介质传播到另外一种介质时,电磁波会发生折射,当物质内部的折射率分布非均匀时,电磁波就会向折射率比较大的位置偏折,通过设计超材料中每一点的电磁参数,就可对超材料的折射率分布进行调整,进而达到改变电磁波的传播路径的目的。 As common knowledge we know, the refractive index of electromagnetic waves - ^ εχμ proportional relationship, when a bunch of electromagnetic wave propagation from one medium to another medium, the electromagnetic wave is refracted, when the refractive index of the non-uniform distribution of the material inside, will deflect electromagnetic waves to the refractive index of a relatively large position, by designing metamaterial electromagnetic parameters of each point, it can index metamaterial to adjust the distribution, thus achieve the purpose of changing the electromagnetic wave propagation path. 根据上述原理可以通过设计超材料面板10的折射率分布使从辐射器本体20发出的电磁波汇聚在一个较小的区域。 According to this principle can design a metamaterial panel refractive index profile 10 of electromagnetic waves emitted from the radiation body 20 converge in a smaller area. 汇聚的区域的大小可依据实际的需求来设定,通过改变超材料面板10的折射率分布来设置所需的汇聚区域范围。 The size of the region of convergence can be set according to the actual demand, to set the convergence zone range by changing the metamaterial desired refractive index profile 10 of the panel. 在实际应用中,可根据患者病情需要,通过调整辐射器本体20的功率来改变微波热疗辐射器100的辐射强度,从而改变汇聚区域的温度,使得适合病患部位的治疗需求。 In practice, according to the patient's condition may require, by adjusting the power of the radiator main body 20 to vary the intensity of the microwave radiation hyperthermia radiator 100, thereby changing the temperature of the convergence zone so that the demand for the treatment of patients site. 另外,还可以通过改变超材料面板10与辐射器本体20距离来调节电磁波的汇聚区域。 In addition, you can also change the metamaterial panel 10 and the radiation from the body 20 to adjust the convergence area of electromagnetic waves.

[0030] 图I所示的超材料面板10包括至少一个超材料片层3,每个超材料片层3包括片状的基板I和附着在基板I上的多个人造微结构2,每个人造微结构2以及其所附着的基板I所占部分即为一个超材料单元。 [0030] The meta-material panel 10 shown in Figure I comprises at least one metamaterial sheets 3, each sheet 3 metamaterial 2, each comprising a sheet-like substrate I and I adhered to the substrate a plurality of artificial microstructures making the microstructure of the substrate 2, and it is attached is a part I share metamaterial unit. 实施例中超材料面板10由多个超材料片层3堆叠形成,这各个超材料片层3之间等间距排列地组装,或两两片层之间直接前、后表面相粘合地连接成一体。 Example Super material panel 10 is formed by a plurality of sheets 3 stacked metamaterial, directly before each metamaterial between lamellar spacing between 3 and so arranged to assemble, or between two sheets, after connecting a bonding surface one. 具体实施时,超材料片层3的数目可依据需求来进行设计。 Specific implementation, the number of super sheet material 3 may be designed according to demand. 每个超材料片层3由多个超材料单元阵列形成,整个超材料面板10可看作是由多个超材料单元沿Χ、Υ、Ζ三个方向阵列排布而成。 Each meta-material sheet 3 is formed of a plurality of cell arrays metamaterial, the metamaterial entire panel 10 can be viewed as composed of three directions along a plurality of metamaterial unit Χ, Υ, Ζ arrayed together. 本发明所采用的具有电磁波汇聚功能的超材料面板10中,每个超材料单元的边长为入射电磁波波长的1/5到1/10之间。 The present invention is used in electromagnetic metamaterials panel has aggregation functions 10, each side metamaterial unit wavelength of the incident electromagnetic wave between 1/5 to 1/10. 本实施例中每个超材料片层3的折射率分布均相同,这里为了描述清楚仅对一个超材料片层3的折射率分布规律进行详细说明,其余各超材料片层3的折射率分布规律均相同。 In this embodiment each of the meta-material sheet 3 are the same refractive index profile, where the distribution of the refractive index in order to describe clearly only a metamaterial sheet 3 will be described in detail, the refractive index of the rest of the material sheet 3 super distribution They are the same regularity. 通过对人造微结构2的拓扑图案、几何尺寸以及其在基板I上分布,使每个超材料片层3的折射率分布满足第一规律:超材料片层3包括一个圆形区域和多个与圆形区域同心的环形区域且圆心处的折射率最大;圆形区域和环形区域内折射率随着半径的增大连续减小且相同半径处的折射率相同;多个区域中至少存在两个相邻的第一区域及第二区域,第一区域内超材料的折射率随着半径的增大从nl连续减小到n2,第二区域内超材料折射率随着半径的增大从n3连续减小到n4,且满足n3> n2,即两区域相邻处存在折射率跳变。 Through artificial microstructure topology pattern 2, the geometry of the substrate as well as their distribution on I, so that each slice refractive index metamaterial profile satisfies a first rule of 3: metamaterial includes a circular region and a plurality of sheets 3 circular area concentric annular region and having a refractive index at the center of the largest; the same refractive index as the radius increases the refractive index decreases continuously and at the same radius circular area and the annular region; a plurality of regions in the presence of at least two adjacent the first region and the second region, the first region refractive index metamaterial increases as the radius decreases continuously from nl to n2, the refractive index of the material over the second region with increasing radius from n3 decreases continuously to n4, and satisfy n3> n2, namely the existence of two regions adjacent to the refractive index jump.

[0031] 如图2所示超材料面板10由多个折射率分布规律相同的超材料片层3堆叠形成,所以本发明的超材料面板10的折射率分布满足第一规律,图3是图2所示的超材料面板10的折射率随半径变化的示意图。 [0031] 2 metamaterial panel by a plurality of refractive index distribution of the same sheet material 10 over a stack 3 is formed, so the index metamaterial panel of the present invention satisfies the first distribution law 10, FIG. 3 is index metamaterial panel 10 of FIG. 2 with varying radii Fig. 如图3所示超材料面板10包括3个区域,第一区域的半径长度为LI,在该区域内沿半径增加的方向每个超材料单元的折射率依次为ai、a2、 3 metamaterial panel 10 comprises three regions, a first region of the length of the radius LI, the region in the radial direction of increasing the refractive index metamaterial unit each in the order of ai, a2,

[0035] 其中为不小于2的自然数,式⑴⑵(3)均不同时取等号。 [0035] where a natural number of not less than 2, the formula ⑴⑵ (3) are not simultaneously take equal sign.

[0036] 利用超材料面板10将从辐射器本体20发出的电磁波汇聚在一个较小的区域,越靠近超材料面板10的边缘处入射电磁波和出射电磁波之间所夹的偏折角越大。 [0036] The use of electromagnetic metamaterials panel 10 from the radiation emitted by body 20 converge in a smaller area, closer to the edge of the metamaterial panel 10 of the incident electromagnetic wave and the exit deflection angle greater sandwiched between the electromagnetic wave. 作为公知常识可知相邻超材料单元之间的折射率变化量越大,则电磁波的偏折角越大。 As common knowledge shows that the larger the refractive index of the amount of change in the neighboring metamaterial unit between the electromagnetic deflection angle increases. 因此,为了实现超材料面板10边缘处的电磁波的大角度偏折以及实现平面波形式的电磁波,各个区域内超材料单兀的折射率变化满足如下关系: Therefore, in order to achieve electromagnetic metamaterial panel 10 at the edge of a large deflection angle and the realization of a plane wave in the form of electromagnetic waves, within each region metamaterial single refractive index change Wu satisfy the following relation:

[0037] (afa2) ( (a2_a3) ( ...... ( (an—faj ( (bfh) ( (b2_b3)(...... [0037] (afa2) ((a2_a3) (...... ((an-faj ((bfh) ((b2_b3) (......

[0038] 满足上述折射率变化量关系的超材料面板10,对于从辐射器本体20发出的电磁波,以折射率为B1的超材料单元为圆心,随着半径的增大超材料面板10在yz平面上的折射率变化量逐渐增大,因此以&1所在的超材料单元为圆心,随着半径的增大入射的电磁波出射时偏折角度大,越靠近圆心所在的超材料单元入射的电磁波其出射偏折角越小。 [0038] satisfy the above amount of change in the relationship between the refractive index metamaterials panel 10, the electromagnetic radiation from the body 20 sent to B1 refractive index metamaterial unit as the center, as the radius increases metamaterial panel 10 in yz the amount of change in the refractive index in the plane is gradually increased, and therefore the & metamaterial unit 1 is located as the center, with the increase in the radius of an incident electromagnetic wave emitted when a large deflection angle, where incident closer to the center of an electromagnetic wave which metamaterial unit Angular out Shepian smaller. 通过一定的设计和计算,使得这些偏折角依次满足一定的规律,即可实现电磁波汇聚。 Through certain design and calculation, so that these deflection angle in order to meet certain rules, you can achieve the convergence of electromagnetic waves. 本发明的基于超材料的微波热疗辐射器通过设计各个超材料单元的人造微结构2,得到该单元的介电常数ε和磁导率μ,进而对超材料面板10的折射率分布进行设计使得各个相邻超材料单元的折射率的变化量An能实现电磁波特定的偏折角度,即可实现球面波形式发散的电磁波转变为平面形式的电磁波。 The present invention is based on metamaterial microwave hyperthermia radiator by designing synthetic microstructures respective metamaterial unit 2, to obtain the dielectric constant ε and the magnetic permeability of the cell μ, and then to index metamaterial distribution panel design 10 so that the amount of change of the respective adjacent refractive index metamaterial unit An electromagnetic wave can achieve a specific deflection angle can be realized in the form of a spherical wave diverging waves into a planar form of electromagnetic waves.

[0039] 为了更直观的表示超材料片层3在yz面上折射率折射率分布规律,将折射率相同的超材料单元连成一条线,并用线的疏密来表示折射率的大小,线越密折射率越大,则符合以上所有关系式的超材料片层3的折射率分布如图4所示。 [0039] For a more visual representation metamaterial sheets 3 in the refractive index distribution of yz plane, the same refractive index metamaterial unit connected into a line, and with a line to indicate the size of the refractive index, density, line The more dense the refractive index increases, the above relationship meets the sheet material 3 over the refractive index profile shown in Fig.

[0040] 实验证明,相同图案的人造微结构2,其几何尺寸与介电常数成ε正比,因此在入射电磁波确定的情况下,通过合理设计人造微结构2的拓扑图案和不同尺寸的人造微结构2在超材料片层上的排布,就可以调整超材料面板10的折射率分布,进而实现球面波形式发散的电磁波转变为平面形式的电磁波。 [0040] Experimental results show that the microstructure of the same synthetic pattern 2, the geometric dimensions and the dielectric constant ε is proportional to, and therefore in the case of an incident electromagnetic wave is determined by the rational design of artificial synthetic micro-topography in a patterning microstructures and different sizes of 2 2 On the metamaterial structure sheet arrangement, you can adjust the refractive index profile metamaterial panel 10, so as to realize the form of a spherical wave diverging waves into a planar form of electromagnetic waves.

[0041] 实现上述折射率和折射率变化量分布关系的人造微结构2有很多种可实现方式,对于平面结构的人造微结构2,其几何形状可以是轴对称也可以非轴对称;对于三维结构,其可以是非90度旋转对称的任意三维图形。 [0041] to achieve the above amount of change in the refractive index and the Distribution of artificial microstructure 2 There are many ways to achieve, for artificial microstructure planar structure 2, its geometry can be non-axial symmetry axis of symmetry is also possible; for three structure, which may be non-rotational symmetry of 90 degrees in any three-dimensional graphics.

[0042] 如图2所示平面的人造微结构2均附着在片状基材I的表面上。 [0042] As shown in Figure 2 the plane of an artificial micro-structure 2 are attached to the surface of the flaky substrate I. 图中人造微结构2呈“工”字形,包括竖直的第一金属丝201和分别连接在第一金属丝201两端且垂直于第一金属丝201的第二金属丝202。 Fig. 2 artificial microstructure were "workers" shape, the first wire includes a vertical 201 and are connected to both ends of the first wire 201 and is perpendicular to the first wire of the second wire 202 201. 超材料面板10由多个相同的超材料片层3构成,每个超材料片层3的yz平面上包括一个圆形区域和多个与圆形区域同心的环形区域且圆心处的人造微结构2的尺寸最大,每个区域内“工”字形的人造微结构2的尺寸随着半径的增大连续减小,且相同半径处的人造微结构2的尺寸相同;多个区域中至少存在两个相邻的第一区域和第二区域,这两个相邻区域内人造微结构2的尺寸变化范围交集为非空,即以人造微结构2尺寸最大处为圆心,随着半径的增大至少依次存在两个相邻的第一区域和第二区域,第二区域内最大的人造微结构2的尺寸大于第一区域内最小的人造微结构2的尺寸。 3 metamaterial panel 10 formed of the same material over a plurality of sheets, artificial microstructures comprise a circular region and a plurality of annular area concentric with the circular area at the center and on the yz plane 3 of each super-material sheet Size 2 is the largest man-made micro-structure in each region "workers" shape size 2 as the radius increases continuously decreases, and the man-made micro-structure of the same size at the same radius of 2; a plurality of regions at least two adjacent the first region and a second region, the size range of artificial micro structure 2. This intersection is non-empty two adjacent regions, that is the maximum size of the microstructure 2 man at the center, as the radius increases the presence of at least two successively adjacent first and second regions, the second largest man-made microstructure region 2 is larger than the size of the first area size of the smallest synthetic microstructure 2.

[0043] 需要说明的是,由于实际上超材料单元是一个立方体而非一个点,因此上述圆形、环形只是近似描述,实际上的折射率相同或基本相同的超材料单元是在一个锯齿形圆周上分布的。 [0043] It should be noted that, due to the fact metamaterial unit is a cube instead of a point, so the above circular, annular described only approximate, in fact, the same or substantially the same refractive index metamaterial unit is in a zig-zag distributed on the circumference. 其具体设计类似于计算机用方形像素点绘制圆形、椭圆形等平滑曲线时进行描点的编程模式(例如OpenGL),当像素点相对于曲线很小时曲线显示为光滑,而当像素点相对于曲线较大时曲线显示有锯齿。 Point of time will be described with specific design is similar to a computer draw a circle, oval smooth curve with a square pixel programming mode (such as OpenGL), when pixels are small relative to the curve is displayed as a smooth curve, and when pixels versus large jagged curve display.

[0045] 应当理解,本发明可以采用“王”字形或“十”字形等对称结构的人造微结构2,也可采用其他非对称结构的人造微结构2,只要每个超材料片层3在yz面上的折射率分布满足上述所有关系式,通过对人造微结构2的形状、尺寸和排布进行设置即可实现电磁波汇聚到一个区域。 [0045] It should be understood that the present invention may employ an artificial micro-structure, "Wang" shaped or "ten" and other symmetric structure 2, may also have other artificial microstructure asymmetric structure 2, as long as each metamaterial sheets 3 yz plane refractive index profile satisfies all the above relation, by artificial microstructure shape, size and arrangement 2 can be set to achieve a convergence of the electromagnetic wave region.

[0046] 具体实施时,可通过计算和仿真得出其介电常数和磁导率,然后不断调整人造微结构2的形状和尺寸,直到其介电常数和磁导率的值满足上述折射率分布。 [0046] The specific implementation can be drawn from its permittivity and permeability by calculation and simulation, and then continue to adjust artificial microstructure 2 shapes and sizes until its value permittivity and permeability to satisfy the above refractive index Distribution.
