Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that positioning of the C arm and the table is not carried out speedily, when determining a photographing position during angiographic examination, because it is difficult for an operator to push two different push buttons simultaneously while moving a grip vertically in order to move a C arm and to move a table vertically and the table cannot be moved vertically until movement of the C arm is finished. <P>SOLUTION: A memory practice switch 23 doubles as a switch that permits vertical movement of the table. After an appropriate switch is designated from memory switches 20, the grip 11 is moved vertically while pushing the memory practice switch 23. By doing so, the C arm 3 and the table 16 are moved simultaneously. With such a configuration, time necessary to determine a photographing position is reduced and an examination is carried out speedily. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

本発明はX線透視撮影装置に関する。   The present invention relates to a fluoroscopic imaging apparatus.

X線透視撮影装置を用いて血管造影検査を行う様子を図2に示す。術者15は透視および撮影を行うとき、検診台5の天板16上に被検者4を載置し、例えば天板16の側面に取り付けられた操作部17を操作して天板16を移動させ、さらにX線管1および、例えばフラットパネル型検出器により構成されるX線受光部2をそれぞれ両端に対向して取り付けたCアーム3を回転、または移動させて、被検者4の撮影部位を撮影に適した位置に配置する。そのため天板16は矢印5aで示すように水平動可能に、また矢印5bで示すように上下動可能に検診台5により保持されており、Cアーム3は例えば天井から懸垂されたアーム保持部(図示しない)により、X線管1およびX線受光部2が矢印3cで示すように被検者4の体軸周りに回転可能に、さらに矢印3bで示すように体軸を含む面上を回転可能に保持され、さらにアーム保持部は天井に取り付けられたレール(図示しない)等により、Cアーム3とともに矢印3aで示すように水平動可能に保持されている。   FIG. 2 shows a state in which an angiographic examination is performed using an X-ray fluoroscopic apparatus. The operator 15 places the subject 4 on the top plate 16 of the examination table 5 when performing fluoroscopy and imaging, and operates the operation unit 17 attached to the side surface of the top plate 16 to operate the top plate 16. The X-ray tube 1 and an X-ray light receiving unit 2 constituted by, for example, a flat panel detector are attached to both ends of the C-arm 3 so as to be rotated or moved. The imaging part is arranged at a position suitable for imaging. Therefore, the top plate 16 is held by the examination table 5 so as to be horizontally movable as indicated by an arrow 5a and vertically movable as indicated by an arrow 5b, and the C arm 3 is an arm holding portion (for example, suspended from a ceiling). (Not shown), the X-ray tube 1 and the X-ray light receiving unit 2 can rotate around the body axis of the subject 4 as indicated by the arrow 3c, and further rotate on the plane including the body axis as indicated by the arrow 3b. Further, the arm holding portion is held by a rail (not shown) attached to the ceiling so as to be movable horizontally along with the C arm 3 as indicated by an arrow 3a.

図5は操作部17について本発明に関係する部分を示す図である。ここで操作部17の筐体13には、例えばマイクロコンピュータやメモリ等により構成される制御部(図示しない)が内蔵されており、メモリスイッチ20を構成する複数個のスイッチのそれぞれに対応してCアーム3を配置する位置情報が記憶されている。さらに図2も含めて説明すると、術者15はCアーム3を撮影に適した位置および角度に配置するとき、メモリスイッチ20を構成する複数個のスイッチの中から希望する位置情報に対応するスイッチを選択指定する。これにより制御部に記憶された位置情報のうち希望するものを選ばれ、その後筐体13に取り付けられたグリップ11の上面に設けられたメモリ実行スイッチ21を押すと、Cアーム3が所望の位置および角度になるように移動および回転を行うので、術者15はCアーム3が所望の位置および角度に配置された後、メモリ実行スイッチ21を押すのをやめる。同様の機能を有する操作部は例えば特許文献1等に記載されている。   FIG. 5 is a diagram showing portions related to the present invention with respect to the operation unit 17. Here, the housing 13 of the operation unit 17 incorporates a control unit (not shown) constituted by, for example, a microcomputer and a memory, and corresponds to each of a plurality of switches constituting the memory switch 20. Position information for arranging the C-arm 3 is stored. Further, including FIG. 2, when the operator 15 arranges the C-arm 3 at a position and angle suitable for imaging, a switch corresponding to desired position information from among a plurality of switches constituting the memory switch 20. Select and specify. As a result, the desired position information selected from the position information stored in the control unit is selected, and when the memory execution switch 21 provided on the upper surface of the grip 11 attached to the housing 13 is pressed, the C arm 3 is moved to the desired position. Therefore, the surgeon 15 stops pressing the memory execution switch 21 after the C-arm 3 is arranged at a desired position and angle. An operation unit having the same function is described in, for example, Patent Document 1.

またグリップ11は筐体13に遠い側を矢印Aで示すように上げ下げ可能に筐体13に取り付けられており、術者15はグリップ11の上面に設けられた天板上下動許可スイッチ22を押した状態で、グリップ11を上げ下げすることにより天板16の上下動を行うことができる。すなわち天板16は天板上下動許可スイッチ22が押された状態でグリップ11が中立位置より上に持ち上げられると上昇し、下に押し下げられると下降し、中立位置に置かれると停止するが、天板上下動許可スイッチ22が押されていないときグリップ11を上げ下げしても上下動を行わない。
特開平8−150137号公報
The grip 11 is attached to the casing 13 so that the side far from the casing 13 can be raised and lowered as indicated by an arrow A, and the operator 15 presses the top plate up / down movement permission switch 22 provided on the upper surface of the grip 11. In this state, the top plate 16 can be moved up and down by raising and lowering the grip 11. That is, the top plate 16 rises when the grip 11 is lifted above the neutral position while the top plate up / down movement permission switch 22 is pushed, descends when the grip 11 is pushed down, and stops when the grip 11 is placed at the neutral position. Even if the grip 11 is raised or lowered when the top plate up / down movement permission switch 22 is not pressed, the up / down movement is not performed.
JP-A-8-150137

X線透視撮影装置を用いて血管造影検査を行うときの撮影位置決めの方法は例えば上記のようなものであるが、この方法では術者15はCアーム3が所望の位置および角度に配置されるまでメモリ実行スイッチ21を押しつづけなければならないため、同時に天板上下動許可スイッチ22も押し、かつグリップ11を上げ下げすることは困難で、その結果Cアーム3と天板16を同時に動かすことが困難で、順次動かさざるを得なかった。このことは検査を迅速に行う妨げになっている。本発明はこの問題を解決するためのものである。   An imaging positioning method when an angiographic examination is performed using an X-ray fluoroscopic imaging apparatus is, for example, as described above. In this method, the operator 15 places the C-arm 3 at a desired position and angle. Since the memory execution switch 21 must be continuously pressed, it is difficult to simultaneously press the top plate up / down movement permission switch 22 and raise and lower the grip 11, and as a result, it is difficult to move the C arm 3 and the top plate 16 simultaneously. So I had to move sequentially. This hinders rapid testing. The present invention is intended to solve this problem.

請求項1記載の発明は上記の目的を達成するために、被検者を載置する検診台の天板の上下動を許可する許可手段と、前記許可手段により上下動が許可された状態で前記天板を上下動させる操作を行う操作手段と、X線管およびX線受光部を両端に対向して保持する保持装置についての複数の位置情報を記憶する記憶手段と、前記記憶手段に記憶された複数の位置情報から任意の1個を指定する位置情報指定手段と、前記保持装置が前記位置情報指定手段により指定された配置になるように動作の実行を指示する保持装置動作実行指示手段を備えたX線透視撮影装置において、前記保持装置動作実行指示手段が前記許可手段の機能も兼ねるように構成されるX線透視撮影装置である。   In order to achieve the above-mentioned object, the invention according to claim 1 permits the vertical movement of the top of the examination table on which the subject is placed, and permits the vertical movement by the permission means. Storage means for storing a plurality of pieces of positional information about an operating means for moving the top plate up and down, a holding device for holding the X-ray tube and the X-ray light receiving portion opposite to both ends, and storing in the storage means Position information designating means for designating an arbitrary one of the plurality of position information, and holding device operation execution instructing means for instructing execution of the operation so that the holding device has the arrangement designated by the position information designating means An X-ray fluoroscopic apparatus comprising: the holding device operation execution instructing unit also functions as the permission unit.

本発明によりメモリ実行スイッチが従来の天板上下動許可スイッチの機能も兼ねることになるので、メモリスイッチのうち適当なスイッチを指定した後、メモリ実行スイッチを押しながらグリップを上げ下げすることにより、Cアームと天板を同時に動かすことが可能になり、撮影位置決めに要する時間が短縮され、検査を迅速に行うことができるようになる。   According to the present invention, the memory execution switch also functions as a conventional top plate up / down movement permission switch. Therefore, after designating an appropriate switch among the memory switches, the grip is raised and lowered while pressing the memory execution switch. It becomes possible to move the arm and the top plate at the same time, and the time required for imaging positioning is shortened, so that the inspection can be performed quickly.

本発明の最良の形態を図1〜図4により説明する。透視および撮影を行うとき、術者15は検診台5の天板16上に被検者4を載置して、例えば天板16の側面に取り付けられた操作部18を操作して、天板16を移動させ、さらにX線管1および、例えばフラットパネル型検出器により構成されるX線受光部2をそれぞれ両端に対向して取り付けたCアーム3を回転、または移動させて、被検者4の撮影部位を撮影に適した位置に配置する。そのため天板16は矢印5aで示すように水平動可能に、また矢印5bで示すように上下動可能に検診台5により保持されており、Cアーム3は例えば天井から懸垂されたアーム保持部(図示しない)により、X線管1およびX線受光部2が矢印3cで示すように被検者4の体軸周りに回転可能に、さらに矢印3bで示すように体軸を含む面上を回転可能に保持され、さらにアーム保持部は天井に取り付けられたレール(図示しない)等により、Cアーム3とともに矢印3aで示すように水平動可能に保持されている。   The best mode of the present invention will be described with reference to FIGS. When performing fluoroscopy and imaging, the operator 15 places the subject 4 on the top plate 16 of the examination table 5 and operates the operation unit 18 attached to the side surface of the top plate 16, for example. 16 is further moved, and the X-ray tube 1 and the C-arm 3 mounted with the X-ray light receiving unit 2 constituted by, for example, a flat panel detector facing each end are rotated or moved to move the subject. 4 is arranged at a position suitable for imaging. Therefore, the top plate 16 is held by the examination table 5 so as to be horizontally movable as indicated by an arrow 5a and vertically movable as indicated by an arrow 5b, and the C arm 3 is an arm holding portion (for example, suspended from a ceiling). (Not shown), the X-ray tube 1 and the X-ray light receiving unit 2 can rotate around the body axis of the subject 4 as indicated by the arrow 3c, and further rotate on the plane including the body axis as indicated by the arrow 3b. Further, the arm holding portion is held by a rail (not shown) attached to the ceiling so as to be movable horizontally along with the C arm 3 as indicated by an arrow 3a.

図1は図2に示す操作部18について本発明に関係ある部分を示す図である。ここで操作部18の筐体13には、図3に示す、例えばマイクロコンピュータやメモリ等により構成される制御部24が内蔵されており、メモリスイッチ20を構成する複数個のスイッチのそれぞれに対応してCアーム3を配置する位置情報が記憶されている。なお図3はX線透視撮影装置の本発明に関係する部分を説明するためのブロック図であり、図4はその動作を示すフローチャートである。以下図1から図4を用いて本発明によるX線透視撮影装置の動作について説明する。   FIG. 1 is a diagram showing portions related to the present invention in the operation unit 18 shown in FIG. Here, the housing 13 of the operation unit 18 incorporates a control unit 24 constituted by, for example, a microcomputer or a memory as shown in FIG. 3, and corresponds to each of a plurality of switches constituting the memory switch 20. Thus, position information for arranging the C-arm 3 is stored. FIG. 3 is a block diagram for explaining a portion of the X-ray fluoroscopic apparatus related to the present invention, and FIG. 4 is a flowchart showing its operation. The operation of the X-ray fluoroscopic apparatus according to the present invention will be described below with reference to FIGS.

術者15はCアーム3を撮影に適した位置および角度に配置するために、メモリスイッチ20を構成する複数個のスイッチの中から希望する位置情報に対応するスイッチを選択指定する。これにより制御部24に記憶された位置情報のうち希望するものが選ばれる(S1)。その後筐体13に取り付けられたグリップ11の上面に設けられたメモリ実行スイッチ23が押されると(S2)、制御部24はCアーム駆動部25にCアーム3が所望の位置および角度になるように移動および回転を行うよう指示する(S3)。   The operator 15 selects and designates a switch corresponding to desired position information from among a plurality of switches constituting the memory switch 20 in order to arrange the C-arm 3 at a position and angle suitable for imaging. As a result, the desired position information stored in the control unit 24 is selected (S1). Thereafter, when the memory execution switch 23 provided on the upper surface of the grip 11 attached to the housing 13 is pressed (S2), the control unit 24 causes the C-arm drive unit 25 to place the C-arm 3 at a desired position and angle. Is instructed to move and rotate (S3).

またグリップ11は筐体13に遠い側を矢印Aで示すように上げ下げ可能に筐体13に取り付けられており、術者15がグリップ11の上面に設けられたメモリ実行スイッチ23を押した状態でグリップ11を上げ下げすると、制御部24は天板駆動部26に天板16の上下動を指示する。すなわち制御部24はメモリ実行スイッチ23が押されている場合(S2)Cアーム3の移動を開始する(S3)とともに、グリップ11の位置を確認し(S4)、グリップ11が中立位置より上に持ち上げられていると天板16を上昇させ(S5)、下に押し下げられていると下降させ(S7)、中立位置に置かれていると停止させる(S6)が、メモリ実行スイッチ23が押されていないときグリップ11を上げ下げしても上下動は行われない(S2)。そして術者15がメモリ実行スイッチ23を押すのをやめると(S8)、Cアーム3および天板16が動作中か否かに関係なく、制御部24はCアーム駆動部25および天板駆動部26にそれぞれCアーム3および天板16の動作の停止を指示して(S9)動作を終了する。   The grip 11 is attached to the housing 13 so that the side far from the housing 13 can be raised and lowered as indicated by an arrow A, and the operator 15 presses the memory execution switch 23 provided on the upper surface of the grip 11. When the grip 11 is raised and lowered, the control unit 24 instructs the top plate driving unit 26 to move the top plate 16 up and down. That is, when the memory execution switch 23 is pressed (S2), the control unit 24 starts the movement of the C arm 3 (S3), confirms the position of the grip 11 (S4), and the grip 11 is above the neutral position. When it is lifted, the top 16 is raised (S5), when it is pushed down, it is lowered (S7), and when it is placed at the neutral position, it is stopped (S6), but the memory execution switch 23 is pushed. When the grip 11 is not being moved, the vertical movement is not performed even if the grip 11 is raised or lowered (S2). When the operator 15 stops pressing the memory execution switch 23 (S8), the control unit 24 controls the C arm drive unit 25 and the top plate drive unit regardless of whether the C arm 3 and the top plate 16 are in operation. 26 is instructed to stop the operations of the C arm 3 and the top plate 16 (S9), and the operation is terminated.

上記のような構成によりメモリスイッチ20のうち適当なスイッチを指定した後、メモリ実行スイッチ23を押しながらグリップ11を上げ下げすることにより、Cアーム3と天板16を同時に動かすことが可能になるので、術者15はメモリ実行スイッチ23を押した状態でグリップ11を上げ下げして天板16の上下動を行い、天板16の上下動およびCアーム3の動作が終了した後、メモリ実行スイッチ23を押すのをやめる。これにより撮影位置決めに要する時間が短縮され、検査を迅速に行うことができるようになる。   After designating an appropriate switch among the memory switches 20 with the above configuration, the C arm 3 and the top plate 16 can be moved simultaneously by raising and lowering the grip 11 while pressing the memory execution switch 23. The surgeon 15 raises and lowers the grip 11 while pushing the memory execution switch 23 to move the top plate 16 up and down. After the top plate 16 moves up and down and the C-arm 3 is finished, the memory execution switch 23 is operated. Stop pressing. As a result, the time required for imaging positioning is shortened, and the inspection can be performed quickly.
