Description

この発明は、被験者体の呼吸動作で物理的体動がある体幹部の複数の部分に、移動量を検出できる検出手段を設置し、肺活呼吸による部動きと腹式呼吸による腹部の動きをモニターして、呼吸による被検者の体幹部の合成変位量を高精度にモニターできるようにした多点検出型呼吸モニター装置を提供しようとするものである。 This invention installs detection means capable of detecting the amount of movement in a plurality of parts of the trunk where there is physical movement in the breathing motion of the subject body, and monitors the movement of the abdomen due to the active breathing and the abdominal breathing. Thus, it is an object of the present invention to provide a multi-point detection type respiratory monitor device that can monitor the combined displacement of the trunk of a subject due to respiration with high accuracy.

CT(コンピュータ断層)装置や放射線治療装置で撮像や治療照射を行なう場合、被検者の対象部位が体幹部である場合、被検者の対象部位は被検者の呼吸による体動により対象部位の位置が安定しなかった。したがって、撮像画像の品質劣化や治療部位以外の正常組織への照射が行なわれるなどの問題があり、レーザや赤外線による患者の体動量の電気的検出を行い、体動に同期した信号で撮像や治療照射を行なう、いわゆる呼吸同期動作が従来より行なわれている。
特にありません。
When imaging or treatment irradiation is performed with a CT (computer tomography) apparatus or a radiotherapy apparatus, when the subject part of the subject is the trunk, the subject part of the subject is subject to body movement due to the subject's breathing. The position of was not stable. Therefore, there are problems such as deterioration of the quality of the captured image and irradiation of normal tissues other than the treatment site, and electrical detection of the patient's body movement amount by laser and infrared rays, and imaging with a signal synchronized with body movement A so-called respiratory synchronization operation for performing treatment irradiation has been conventionally performed.
Nothing in particular.

しかしながら、従来方式の呼吸同期は被検者の体幹部の胸部か腹部のいずれかにのみレーザや赤外線を当て、被検者の体幹部の動きを検出することを行っており、胸式呼吸か腹式呼吸のいずれかしか検出できなかった。また、レーザや赤外線を用いた呼吸移動検出はレーザや赤外線センサや電気的センサを用いており、さらにそれらの呼吸移動量を信号処理するアナログ回路や演算用のコンピュータを用いる必要があって装置が複雑化し、高価になるという問題があった。 However, in the conventional method of respiratory synchronization, only the chest or abdomen of the subject's trunk is irradiated with laser or infrared light to detect the movement of the subject's trunk, Only one of abdominal breathing could be detected. In addition, respiratory movement detection using lasers or infrared rays uses lasers, infrared sensors, or electrical sensors, and it is necessary to use an analog circuit for signal processing of the respiratory movement amount or a computer for calculation. There was a problem that it was complicated and expensive.

例えば、胸部や腹部の放射線治療の際にはPTV(計画標的体積:Planning target volume)縮小の目的から呼吸停止が重要であり、様々な呼吸停止法が試みられている。そして、呼吸モニタリング下の照射が盛んに行なわれているが、胸部または腹部の1点の位置情報によるものであるために、腹式、胸式の呼吸が複雑に混じり合った自然呼吸の換気量や腫瘍の位置情報を正確に反映するものではなかった。 For example, during radiotherapy of the chest and abdomen, respiratory arrest is important for the purpose of reducing PTV (Planning target volume), and various respiratory arrest methods have been attempted. Although irradiation under respiratory monitoring is actively performed, it is based on positional information of one point of the chest or abdomen, so the ventilation volume of natural breathing, which is a complex mixture of abdominal and chest breathing And did not accurately reflect tumor location information.

また、以前より医療の現場では呼吸モニタリング装置を用いない自己呼吸停止法を行なっているが、この自己呼吸停止法を検証した結果、自己呼吸停止法についての理解が十分でない患者は自己呼吸停止の精度が著しく悪いため、かねてからより理解し易く精度の高い呼吸停止法および呼吸モニタリング装置の開発が望まれていた。 In addition, the self-breathing stop method that does not use a breath monitoring device has been used in the medical field for some time, but as a result of verifying this self-breathing stop method, patients who do not fully understand the self-breathing stop method Since the accuracy is remarkably poor, it has long been desired to develop a respiratory stop method and a respiratory monitoring device that are easier to understand and have higher accuracy.

Reference numeral 13 denotes a slide hole provided in the leg portion 12, and reference numeral 14 denotes a height adjusting screw.

この発明の多点検出型呼吸モニター装置は前記ハウジング11上に取り付けられている。すなわち、ハウジング11の天板には装置の取付口15が設けられ、その上部にコ字状の支持枠16が取付ねじ17によって固定されている。この支持枠16も透明プラスチック製であることが望ましい。支持枠16の天板部にはほぼ中央にやや広い開口部18が、またその両側に長さ方向に延びるスライド孔19,19がそれぞれ形成されている。

位置調整板20には軸棒22が吊下げるように取り付けられている。すなわち前記開口部18内に、軸棒22の上端に取付けた抜け止め部23が配置され、軸棒22の下端が支持枠16の内部に位置している。軸棒22の下端には支持アーム24が支持ポイントにおいて首振り可能に軸着され、また支持アーム24は前記軸着位置から所定の間隔で、連結アーム25をそのほぼ中間位置で軸支し、連結アーム25を支持ポイントにおいて首振り可能に支持している。特に連結アーム25の軸着部分は多少の遊びがあるよう遊嵌しておくことが望ましい。
The multi-point detection type respiratory monitoring device of the present invention is mounted on the housing 11. That is, the top plate of the housing 11 is provided with an attachment port 15 of the apparatus, and a U-shaped support frame 16 is fixed to the upper part of the top plate by an attachment screw 17. The support frame 16 is also preferably made of transparent plastic. In the top plate portion of the support frame 16, a slightly wide opening 18 is formed in the center, and slide holes 19 and 19 extending in the length direction are formed on both sides thereof.
A position adjusting plate 20 is held by position adjusting screws 21 attached to the slide holes 19 and 19 so as to be orthogonal to the top plate along the top plate of the support frame 16. Therefore, the position adjusting plate 20 can move in the length direction of the slide holes 19, 19 according to the operation of the position adjusting screw 21. An angle gauge 20-1 is attached to the tip of the position adjustment plate 20.
A shaft bar 22 is attached to the position adjustment plate 20 so as to be suspended. That is, a retaining portion 23 attached to the upper end of the shaft rod 22 is disposed in the opening 18, and the lower end of the shaft rod 22 is located inside the support frame 16. A support arm 24 is pivotally attached to the lower end of the shaft rod 22 so as to be able to swing at a support point. The support arm 24 pivotally supports the connecting arm 25 at a substantially intermediate position at a predetermined interval from the shaft attachment position. The connecting arm 25 is supported at a support point so as to be able to swing. In particular, it is desirable that the shaft attachment portion of the connecting arm 25 be loosely fitted so that there is some play.

図2に示すように、この連結アーム25の両端には、鉛直方向にプローブ26,26がそれぞれ取り付けられ、その先端が胸部および腹部の少なくとも2箇所に当接するよう保持されている。
このプローブ26,26間を連結する上記連結アーム25は、スライド孔28を備えた補助アーム27と位置調整ねじ29とを介して伸縮自在であり、被検者の体格等に応じてその長さを調節する。
またプローブ26は上部プローブ26−1と下部プローブ26−2とに分割できるようになっており、上部プローブ26−1の下部に設けた雌ねじ部30に、下部プローブ26−2の上端に設けた雄ねじ部31をねじ込むことにより、複数のサイズの下部プローブ26−2を適宜取り替えることができるようになっている。32はプローブ26を補助アーム27の先端に取り付けるための小ビスである。
さらに、上記支持アーム24の軸着部から支持アーム24とは反対の方向に延長して、変位量表示部33が設けられている。そして変位量表示部33の先端には指示針34が取り付けられている。
図において35は、支持アーム24を延長して設けたバランス棒で、変位量表示部33とのバランスをとってプローブ26,26の先端に過度の負荷がかからないようにするためのものである。
As shown in FIG. 2, probes 26, 26 are attached to both ends of the connecting arm 25 in the vertical direction, and the tips thereof are held so as to abut at least two places on the chest and abdomen.
The connecting arm 25 for connecting the probes 26 and 26 is extendable and retractable via an auxiliary arm 27 having a slide hole 28 and a position adjusting screw 29, and the length thereof depends on the physique of the subject. Adjust.
The probe 26 can be divided into an upper probe 26-1 and a lower probe 26-2. The probe 26 is provided at the upper end of the lower probe 26-2 on the female screw portion 30 provided at the lower portion of the upper probe 26-1. By screwing the male screw part 31, the lower probes 26-2 of a plurality of sizes can be appropriately replaced. Reference numeral 32 denotes a small screw for attaching the probe 26 to the tip of the auxiliary arm 27.
Further, a displacement amount display portion 33 is provided so as to extend from the shaft attachment portion of the support arm 24 in the direction opposite to the support arm 24. An indicator needle 34 is attached to the tip of the displacement amount display unit 33.
In the figure, reference numeral 35 denotes a balance rod provided by extending the support arm 24 and is used to balance the displacement amount display unit 33 so that an excessive load is not applied to the tips of the probes 26 and 26.

したがって、この発明の多点検出型呼吸モニター装置によれば、図3および図4に示すように、被検者の体幹部の胸部および腹部の少なくとも2箇所の変異量をプローブ26,26によって検出する。すなわち、胸部および腹部のプローブ26,26は胸部および腹部に当接してそれぞれの呼吸時の動きに応じて昇降する(図2ないし図4の矢印a,b参照)。その際、連結アーム25に胸部および腹部のプローブ26,26の昇降動作が伝達され、それらの全体としての合成変位量に応じて、連結アーム25の中間位置で支持している支持アーム24の軸支部分も昇降する(矢印c参照)。
支持アーム24の軸支部分が昇降すると、前記支持アーム24とは反対の方向に延長して設けられた変位量表示部33先端の指示針34が首を振る(矢印d参照)。したがって、検出された呼吸による胸部および腹部のプローブ26,26の変異量を統合した支持アーム24における合成変位量が、位置調整板20の先端に取り付けた角度ゲージ20−1の目盛りを指す指示針34によって判定(表示)される。
前記支持アーム24と、支持アーム24とは反対の方向に延長して設けられた変位量表示部33とは、支持アーム24の軸支位置を中心としてその両側に配置されている。支持アーム24の軸支位置から連結アーム25を軸着している位置までの距離l−1と変位量表示部33の長さl−2の比は適宜決定することができるが、l−1:l−2=1:1〜10程度とすることが望ましく、指示針34の振幅の大きさ、指示針34の動きの見易さその他を勘案して決めることができる。
Therefore, according to the multipoint detection type respiratory monitoring apparatus of the present invention, as shown in FIGS. 3 and 4, the amount of mutation in at least two portions of the chest and abdomen of the trunk of the subject is detected by the probes 26 and 26. To do. That is, the chest and abdominal probes 26 and 26 come into contact with the chest and the abdomen and move up and down according to their breathing movements (see arrows a and b in FIGS. 2 to 4). At that time, the lifting and lowering movements of the chest and abdominal probes 26, 26 are transmitted to the connecting arm 25, and the shaft of the support arm 24 supported at the intermediate position of the connecting arm 25 according to the combined displacement amount of them as a whole. The support portion also moves up and down (see arrow c).
When the shaft support portion of the support arm 24 moves up and down, the indicator needle 34 at the tip of the displacement amount display portion 33 provided extending in the direction opposite to the support arm 24 swings the head (see arrow d). Therefore, the combined displacement amount in the support arm 24 that integrates the detected amounts of variation in the chest and abdominal probes 26, 26 due to the detected breathing indicates the scale of the angle gauge 20-1 attached to the tip of the position adjustment plate 20. 34 is determined (displayed).
The support arm 24 and the displacement amount display portion 33 provided so as to extend in the direction opposite to the support arm 24 are disposed on both sides of the support arm 24 with the shaft support position as a center. The ratio of the distance l-1 from the pivot support position of the support arm 24 to the position where the connecting arm 25 is attached to the length l-2 of the displacement amount display unit 33 can be determined as appropriate. : L-2 = 1: 1 to about 10 is preferable, and can be determined in consideration of the amplitude of the indicator needle 34, the visibility of the movement of the indicator needle 34, and the like.

被検者は、図6および図7のように、角度ゲージ20−1における指示針34の上下動作を目視することで自分自身の呼吸の状態を視覚的に認識することができる。図中、41は押しボタンスイッチ、42は押しボタンスイッチ41の押下げで点灯する表示装置で、撮像時や治療照射時に押しボタンスイッチ41を被検者に持たせる。そして、被検者に角度ゲージ20−1における指示針34の上下動作を目視させ、角度ゲージ20−1における指示針34の上下動作の値が被検者に応じて定められた特定位置範囲にある場合に押しボタンスイッチ41を押させる。
そうすることで表示装置42が点灯し、被検者の呼吸状態を遠隔で操作する術者に伝達することができる。また同時にスイッチ信号を平行して検査機器や治療装置に伝達することで、患者の呼吸に同期して装置の検査進行や治療照射の進行を制御する呼吸同期を実施できる。
なお、上記実施例においては角度ゲージ20−1を被検者側から見ることができる位置に設置しているが、位置調整板20の反対側端部にも取り付けることができる。そうすれば、撮像や治療照射を行なう術者においても、被検者の呼吸状態を見ながら、正確に操作することが可能となる。
As shown in FIGS. 6 and 7, the subject can visually recognize his / her breathing state by visually observing the vertical movement of the indicator needle 34 in the angle gauge 20-1. In the figure, 41 is a push button switch, and 42 is a display device that is turned on when the push button switch 41 is depressed. The push button switch 41 is held by the subject during imaging or treatment irradiation. Then, the subject visually observes the vertical movement of the indicator needle 34 in the angle gauge 20-1, and the value of the vertical movement of the indicator needle 34 in the angle gauge 20-1 is within a specific position range determined according to the subject. In some cases, the push button switch 41 is pressed.
By doing so, the display device 42 is turned on, and the respiratory state of the subject can be transmitted to the operator who operates remotely. At the same time, by transmitting the switch signal in parallel to the examination device or the treatment apparatus, it is possible to perform respiratory synchronization that controls the examination progress of the apparatus and the progress of treatment irradiation in synchronization with the patient's breathing.
In addition, in the said Example, although the angle gauge 20-1 is installed in the position which can be seen from the subject side, it can also be attached to the other side edge part of the position adjustment board 20. FIG. In this way, even an operator who performs imaging or treatment irradiation can perform an accurate operation while viewing the respiratory state of the subject.

It is characterized in that it can be controlled independently so as to be within the range.

<考察>
この発明の多点検出型呼吸モニター装置を用いた自発的呼吸停止下での、CTによる腫瘍位置の三次元的再現精度は2mm以内であり、高精度であることが照明された。また、繰り返す呼吸の分析結果により、胸式呼吸と腹式呼吸が混在し、従来型の1点式呼吸モニター装置を用いた場合の位置再現精度は呼吸性移動幅(10-40mm)の4-6分の1程度もずれる可能性が考えられ、本方法のように、多点検出型呼吸モニター装置を用いた自発的呼吸停止下での、腫瘍位置の三次元的再現精度が、従来型1点式呼吸モニター装置に比べて非常に良好であることが証明された。すなわち、胸式呼吸と腹式呼吸とが混在して不安定となる呼吸においても、この発明の多点検出型呼吸モニター装置を用いた自発的呼吸停止下での腫瘍位置の三次元的再現精度は従来型1点式呼吸モニター装置に比べて良好である。このように胸部と腹部の2点を同時に測定する方式の多点検出型呼吸モニター装置は従来になく、胸式呼吸と腹式呼吸とが混在して不安定となる呼吸においても対応できるメリットがある。
この発明の多点検出型呼吸モニター装置である胸腹部2点測定式呼吸モニタリング装置を用いた呼吸停止法は患者に理解が得られやすく、連取時間が大幅に短縮できるというメリットがある。
<Discussion>
The three-dimensional reproduction accuracy of the tumor position by CT under spontaneous breathing stop using the multipoint detection type respiratory monitor device of the present invention is within 2 mm, and it was illuminated that it is highly accurate. In addition, based on the results of repeated respiration analysis, chest respiration and abdominal respiration are mixed, and the position reproducibility when using a conventional single-point respiration monitor is 4-6 of the respiration range (10-40mm) It is possible that the position is shifted by a fraction of a minute. Like this method, the three-dimensional reproducibility of the tumor position under spontaneous breathing stop using a multi-point detection type respiratory monitoring device is one point of the conventional type. It proved to be very good compared to the breathing device. That is, even in breathing that becomes unstable due to a mixture of chest breathing and abdominal breathing, the three-dimensional reproduction accuracy of the tumor position under spontaneous breathing stop using the multipoint detection respiratory monitor device of the present invention is It is better than a conventional one-point respiratory monitor device. Thus, there is no conventional multi-point detection type respiratory monitor device that measures the two points of the chest and abdomen at the same time. .
The breathing stop method using the thoracoabdominal two-point measurement type respiratory monitoring device, which is the multipoint detection type respiratory monitoring device of the present invention, is advantageous in that the patient can easily understand and the continuous time can be greatly shortened.

図8ないし図11はこの発明の多点検出型呼吸モニター装置の第2の実施形態を表わすものである。
図8および図9において、51は被検者の胸部および腹部等の体幹部に被せて被検者が横たわる寝台に装着するスタンドで、この発明の多点検出型呼吸モニター装置を被検者の胸部および腹部等の体幹部上に保持するためのものである。このスタンド51は開口部を下向きとしたコ字状をなし、両側に寝台等に設置可能な据え置き台52を備え、据え置き台52にはスライドガイド53が立設されている。このスライドガイド53には、コ字状スタンド51の脚部54を着脱自在に取り付けることにより、その高さを被検者に応じて変えることができる。55はスライドガイド53に外付けした高さ調節ねじである。
また、スタンド51の上部ブリッジ部56には、測定装置58を取り付けるための組付台57がスライド自在に取り付けられており、その側面には測定装置58を組み付けるためのブラケット59が取り付けられている。
8 to 11 show a second embodiment of the multipoint detection type respiratory monitoring apparatus of the present invention.
8 and 9, 51 is a stand that is placed on the bed on which the subject lies and covers the trunk such as the chest and abdomen of the subject. The multi-point detection type respiratory monitor device of the present invention is attached to the subject. It is for holding on the trunk, such as the chest and abdomen. The stand 51 has a U-shape with an opening facing downward, and includes a stationary table 52 that can be installed on a bed or the like on both sides. A sliding guide 53 is erected on the stationary table 52. By attaching the leg portion 54 of the U-shaped stand 51 to the slide guide 53 in a detachable manner, the height can be changed according to the subject. Reference numeral 55 denotes a height adjusting screw externally attached to the slide guide 53.
Further, an assembly base 57 for attaching the measuring device 58 is slidably attached to the upper bridge portion 56 of the stand 51, and a bracket 59 for attaching the measuring device 58 is attached to the side surface thereof. .

測定装置58を示す図10および図11において、61は測定装置のケーシングで、前記組付台57側面のブラケット59に組み付けることにより、前記組付台57に固定されている。
測定装置のケーシング61の両側にはそれぞれ、先端にプローブ64を備えたロングアーム62およびショートアーム63が首振り自在に取り付けられている。65は、前記プローブ64の下端に回動自在に取り付けたローラである。
なおロングアーム62およびショートアーム63は、それぞれ先端に取り付けた前記プローブ64が被検者の体幹に沿って配置されるよう、測定装置のケーシング61に対して所定の角度で取り付けてある。
次に、71は測定装置のケーシング61の上部に取り付けられた角度ゲージで、扇型に形成されており、その円弧状の周縁部分に角度目盛り72が表示されている。73は角度目盛り72上の所定の角度を指し示す指針で、前記プローブ64の動きに応じて測定装置58により駆動されるようになっている。
In FIG. 10 and FIG. 11 showing the measuring device 58, 61 is a casing of the measuring device, and is fixed to the assembling table 57 by assembling it to a bracket 59 on the side surface of the assembling table 57.
A long arm 62 and a short arm 63 each having a probe 64 at the tip are attached to both sides of the casing 61 of the measuring device so as to freely swing. A roller 65 is rotatably attached to the lower end of the probe 64.
The long arm 62 and the short arm 63 are attached to the casing 61 of the measuring apparatus at a predetermined angle so that the probe 64 attached to the distal end is arranged along the trunk of the subject.
Next, reference numeral 71 denotes an angle gauge attached to the upper portion of the casing 61 of the measuring device, which is formed in a fan shape, and an angle scale 72 is displayed on the arc-shaped peripheral portion. Reference numeral 73 denotes a pointer indicating a predetermined angle on the angle scale 72, and is driven by the measuring device 58 in accordance with the movement of the probe 64.

次に、図12ないし図15に基いて、測定装置の動作原理を説明する。
図12の糸移動量と指針角度の関係を示す模式図において、θは指針の角度、dpは指針プーリの径、dyは糸の直径、Sは糸の移動量を指すものである。
ここにおいて、指針の角度θは次の式(1)で求められる。

Figure 2006263461
・・・(1) Next, the operation principle of the measuring apparatus will be described with reference to FIGS.
In the schematic diagram showing the relationship between the yarn movement amount and the pointer angle in FIG. 12, θ is the pointer angle, dp is the diameter of the pointer pulley, dy is the yarn diameter, and S is the yarn movement amount.
Here, the angle θ of the pointer is obtained by the following equation (1).
Figure 2006263461
... (1)

そこで糸の移動量Sに関係する測定アームのテコ比について検討すると、図13の測定アームのショートアームにおけるテコ比を示す模式図において、L1はショートアーム長、L2はロングアーム長、l1はショートアームテコ長、l2はロングアームテコ長、H1はショートアーム測定高、H2はロングアーム測定高、S1はショートアームテコ移動量、S2はロングアームテコ移動量を指すものである。
ここにおいて、ショートアームテコ移動量S1は次の式(2)で求められる。

Figure 2006263461
・・・(2)
また図14の測定アームのロングアームにおけるテコ比を示す模式図において、ロングアームテコ移動量S2は次の式(3)で求められる。
Figure 2006263461
・・・(3) Therefore, when the leverage ratio of the measurement arm related to the amount of movement S of the yarn is examined, L 1 is the short arm length, L 2 is the long arm length, l in the schematic diagram showing the leverage ratio of the short arm of the measurement arm in FIG. 1 is the short arm lever length, l 2 is the long arm lever length, H 1 is the short arm measuring height, H 2 is the long arm measuring height, S 1 is the short arm lever moving amount, and S 2 is the long arm lever moving amount. Is.
Here, the short arm lever movement amount S 1 is obtained by the following equation (2).
Figure 2006263461
... (2)
Further, in the schematic diagram showing the lever ratio of the long arm of the measurement arm in FIG. 14, the long arm lever movement amount S 2 is obtained by the following equation (3).
Figure 2006263461
... (3)

しかしながら、上記糸の移動量Sを求める場合においては、次の条件を満たす構造でなければならない。
1)表示は両プローブ高さ(移動量)の合計値であること。
2)測定高(入力)と表示(出力)の比率は両アームとも同一であること。

そのため、図15においてショート、ロングそれぞれのS値を計算してみる(図13,14も参考)。
式(2)および(3)により測定高10mm時のS値はそれぞれ、次式(4)および(5)で求められる。

Figure 2006263461
・・・(4)

Figure 2006263461
・・・(5)
ここで、 S1/S2 =0.5 となり前記条件2)を満たさない。
これを満たすには、 S1=2×S2 であればよいので、図15に示すようにロングアーム側テコ長に相当する点に滑車を設けることで S2 の値を2倍にすることができる(注:ロングアーム長は設定により変わるので、S2 値は多少変動する)。
なお、糸は1本で繋がっているので、指針プーリに伝わる糸の移動量Sは両プローブの合計となり、もうひとつの仕様も満たしている。 However, when the movement amount S of the yarn is obtained, the structure must satisfy the following condition.
1) The display shall be the total value of both probe heights (movement amounts).
2) The ratio of measured height (input) and display (output) must be the same for both arms.

For this reason, in FIG. 15, the S values for the short and long are calculated (see also FIGS. 13 and 14).
The S values at the measurement height of 10 mm are obtained by the following equations (4) and (5), respectively, using the equations (2) and (3).
Figure 2006263461
... (4)

Figure 2006263461
... (5)
Here, S 1 / S 2 = 0.5, which does not satisfy the condition 2).
In order to satisfy this, S 1 = 2 × S 2 suffices, so as shown in FIG. 15, the value of S 2 is doubled by providing a pulley at the point corresponding to the long arm side lever length. (Note: Since the long arm length varies depending on the setting, the S 2 value varies somewhat).
Since one yarn is connected, the amount of movement S of the yarn transmitted to the pointer pulley is the sum of both probes, which satisfies another specification.

以上の点から見て、前記装置の分解能(測定高⇔指針角度)は以下のとおりである。
すなわち、式(1)と式(2),(3)により、測定高10mm当たりの指針角度は、次式(6)で求められる。

Figure 2006263461
・・・(6)
From the above point of view, the resolution (measurement height guide angle) of the apparatus is as follows.
In other words, the pointer angle per measurement height of 10 mm is obtained by the following equation (6) from the equations (1), (2), and (3).
