Description

この発明は、核医学診断装置に使用される核医学診断装置用被検者支持装置に関する。 The present invention relates to a subject support device for a nuclear medicine diagnostic device used in a nuclear medicine diagnostic device.

例えば、被検者の乳房の検査を行う乳房検査用核医学診断装置においては、あらかじめ放射性薬剤を投与した被検者の乳房を、トンネル状の検査空間が形成されたリング状の放射線検出部に挿入し、被検者の乳房から放射される対消滅光子を放射線検出部により検出する。そして、その光子を検出した時刻を測定し、放射線検出部における２個の検出器での検出時刻差が一定時間以内の場合にそれを一対の対消滅光子として計数し、さらに、対消滅発生地点を検出した検出器対の直線上の位置であると特定する。このようにして得たエミッションデータを蓄積し、蓄積したエミッションデータを用いて画像再構成を行なうことによりＰＥＴ画像を取得する。そして取得したＰＥＴ画像をモニターに表示するとともに、病院内のサーバに転送する。 For example, in a nuclear medicine diagnostic device for breast examination that examines the breast of a subject, the breast of the subject to whom a radiopharmaceutical has been administered in advance is used as a ring-shaped radiation detection unit in which a tunnel-shaped examination space is formed. A pair of annihilation photons emitted from the breast of the subject is inserted into the radiation detector and detected. Then, the time at which the photon is detected is measured, and when the detection time difference between the two detectors in the radiation detector is within a certain time, it is counted as a pair of pair annihilation photons, and the pair annihilation occurrence point is further detected. Is specified as the position on the straight line of the detector pair. The PET data is acquired by accumulating the emission data obtained as described above and performing image reconstruction using the accumulated emission data. Then, the acquired PET image is displayed on the monitor and transferred to the server in the hospital.

このような乳房検査用核医学診断装置においては、被検者の乳房に対して放射線検出部を位置決めする方法として、被検者を寝台または椅子等において一定の位置に固定した後、放射線検出部を被検者に対して近接させて位置決めする方法と、放射線検出部を固定しておき、その放射線検出部に対して被検者の乳房を挿入して位置決めする方法の二種類の方法がある。 In such a nuclear medicine diagnostic apparatus for breast examination, as a method for positioning the radiation detection unit with respect to the breast of the subject, the radiation detection unit is fixed after the subject is fixed at a fixed position on a bed or a chair. There are two types of methods: a method of positioning the subject in close proximity to the subject and a method of fixing the radiation detection unit and inserting the subject's breast into the radiation detection unit to perform positioning. ..

特許文献１においては、被検者の乳房を挿入する挿入口が形成されたテーブルトップ上に被検者を載置し、被検者の乳房を、挿入口を介して垂れ下がった状態とすることにより、Ｘ線撮像機器に近接させて位置決めする医療処置を行うためのテーブルが開示されている。この特許文献１に記載されたテーブルにおいては、被検者の乳房の大きさに基づき、より大きな、または、より小さな直径の挿入口を有する代替的なインサートを選択して使用する構成となっている。 In Patent Document 1, the subject is placed on a table top formed with an insertion opening for inserting the breast of the subject, and the breast of the subject is hung down through the insertion opening. Discloses a table for performing a medical procedure for positioning the X-ray imaging device in the vicinity thereof. The table described in Patent Document 1 is configured to select and use an alternative insert having an insertion opening with a larger diameter or a smaller diameter based on the size of the breast of the subject. There is.

また、特許文献２においては、被検者の乳房と腋窩部を検査することができる乳房専用核医学診断装置が開示されている。この特許文献２に記載された核医学診断装置においては、座位状態の被検者Ｍの乳房を撮像する環状（リング状）の検出器ユニットと、この検出器ユニットに挿入された腕を支える腕置台とを備えている。この核医学診断装置における検出器ユニットは、乳房に近い方の腕が挿入可能な腕側にある肩部から乳房の付け根までおよぶ内径の孔を有している。 Further, Patent Document 2 discloses a breast-only nuclear medicine diagnostic apparatus capable of examining the breast and axilla of a subject. In the nuclear medicine diagnostic device described in Patent Document 2, an annular (ring-shaped) detector unit for imaging the breast of the subject M in a sitting position, and an arm supporting the arm inserted in the detector unit. It is equipped with a stand. The detector unit in this nuclear medicine diagnostic apparatus has a hole having an inner diameter extending from the shoulder on the arm side into which the arm closer to the breast can be inserted to the base of the breast.

特許文献２に記載されたように、被検者を座位状態で検査した場合には、検査には最大１０分程度の時間を要することから、被検者が同じ姿勢を維持するために苦痛を感じるという問題がある。このため、特許文献１に記載されたように、臥位状態となった被検者に対してその乳房と腋窩部を検査し得る構成とすることが好ましい。しかしながら、このような構成の核医学診断装置は実現されていない。 As described in Patent Document 2, when a subject is inspected in a sitting position, the examination requires a maximum of about 10 minutes, so that the subject suffers from maintaining the same posture. There is a problem of feeling. For this reason, as described in Patent Document 1, it is preferable to adopt a configuration in which the breast and the axilla can be inspected for a subject in a supine position. However, a nuclear medicine diagnostic apparatus having such a configuration has not been realized.

これに対して、特許文献１に記載されたように載置部上に臥位状態で載置した被検者に対して乳房と腋窩部の検査を実行することを可能とするために、被検者の乳房と腋窩部とを配置可能な大きさの検査空間を有する放射線検出部を採用するとともに、この放射線検出部の下方に、被検者の腕部を収納することが可能な空間を形成した構成を採用することが考えられる。このような構成を採用した場合においては、被検者は臥位状態で検査を受けることができ、被検者の負担が小さなものとなる。 On the other hand, as described in Patent Document 1, in order to make it possible to perform an examination of the breast and the axilla on a subject placed on the placing part in the lying position, A radiation detector having an examination space having a size capable of arranging the examiner's breast and axilla is adopted, and a space for accommodating the subject's arm is provided below the radiation detector. It is conceivable to adopt the formed structure. When such a configuration is adopted, the subject can undergo the examination in the lying position, and the burden on the subject becomes small.

このような核医学診断装置を使用して乳房と腋窩部との検査を行うためには、被検者は放射線検出部における腕部の挿入口を介して内部空間に腕部を挿入するために、横を向いた側臥状態を維持する必要がある。上述したように、検査には最大１０分程度の時間を要することから、被検者が身体を動かすことなく側臥状態を維持することは、極めて困難であり、また、被検者にとって苦痛である。 In order to perform an inspection of the breast and the axilla using such a nuclear medicine diagnostic device, the subject is required to insert the arm into the internal space through the insertion opening of the arm in the radiation detector. , It is necessary to maintain a lateral lying position. As described above, since the examination requires a maximum of about 10 minutes, it is extremely difficult for the subject to maintain the lateral recumbent state without moving the body, and it is painful for the subject. ..

この発明は上記課題を解決するためになされたものであり、被検者が側臥状態を容易に維持することを可能とした核医学診断装置用被検者支持装置を提供することを目的とする。 The present invention has been made to solve the above problems, and an object of the present invention is to provide a subject support device for a nuclear medicine diagnostic device that enables a subject to easily maintain a lateral position. ..

以下、この発明の実施の形態を図面に基づいて説明する。図１は、この発明の実施形態に係る核医学診断装置用被検者支持装置を適用する核医学診断装置の斜視図である。また、図２は、この核医学診断装置により被検者Ｍの検査を実行する様子を示す側面概要図である。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a nuclear medicine diagnostic apparatus to which a subject support device for a nuclear medicine diagnostic apparatus according to an embodiment of the present invention is applied. Further, FIG. 2 is a schematic side view showing how the examination of the subject M is performed by this nuclear medicine diagnostic apparatus.

この発明を適用する核医学診断装置は、特に、被検者の乳房とともに、被検者の腋窩部を検査可能なものである。この核医学診断装置は、例えば、マンモ用ＰＥＴ（Ｐｏｓｉｔｒｏｎ Ｅｍｉｓｓｉｏｎ Ｔｏｍｏｇｒａｐｈｙ）装置とも呼称されるものであり、その上部に被検者Ｍを載置するための載置部１１を配置した寝台１４を備える。載置部１１には、被検者Ｍの頭部が配置される凹部１３と、被検者Ｍの乳房および腋窩部を挿入するための挿入口１２とが形成されている。また、寝台１４における載置部１１の下方で本体カバー１６の内部には、被検者Ｍの腕部を収納可能な大きさを有する空間２０が形成されている。被検者Ｍが載置部１１上において腹臥位となった状態において、載置部１１の挿入口１２から空間２０に向けて挿入された被検者Ｍの乳房および腋窩部の周囲には、環状に配置された放射線検出部１５が配設される。 The nuclear medicine diagnostic apparatus to which the present invention is applied is particularly capable of examining the breast of a subject and the axilla of the subject. This nuclear medicine diagnostic apparatus is also called, for example, a mammo PET (Positron Emission Tomography) apparatus, and is provided with a bed 14 on which a placing section 11 for placing the subject M is placed. .. The mounting portion 11 is formed with a recess 13 in which the head of the subject M is placed, and an insertion opening 12 for inserting the breast and axilla of the subject M. A space 20 having a size capable of accommodating the arm portion of the subject M is formed inside the main body cover 16 below the mounting portion 11 of the bed 14. In a state in which the subject M is in the prone position on the placement unit 11, the breasts and the axillary region of the subject M inserted from the insertion opening 12 of the placement unit 11 toward the space 20 are The radiation detection unit 15 arranged in a ring shape is arranged.

この核医学診断装置は、被検者Ｍの乳房および腋窩部を検査するためのものである。この核医学診断装置においては、あらかじめ放射性薬剤を投与した被検者Ｍの乳房および腋窩部を、挿入口１２からトンネル状の検査空間が形成されたリング状の放射線検出部１５に挿入し、被検者Ｍから放射される５１１ｋｅＶの対消滅光子を放射線検出部１５により検出する。そして、その光子を検出した時刻を測定し、放射線検出部１５における２個の検出器での検出時刻差が一定時間以内の場合にそれを一対の対消滅光子として計数し、さらに、対消滅発生地点を検出した検出器対の直線上の位置であると特定する。このようにして得たエミッションデータをコンソール６に蓄積し、コンソール６において蓄積したエミッションデータを用いて画像再構成を行なうことによりＰＥＴ画像を取得する。そして取得したＰＥＴ画像を表示部７に表示するとともに、病院内ネットワーク８を介して病院内のサーバに転送する。 This nuclear medicine diagnosis apparatus is for examining the breast and axilla of the subject M. In this nuclear medicine diagnostic apparatus, the breast and axilla of the subject M, who has been administered with a radiopharmaceutical in advance, is inserted from the insertion opening 12 into a ring-shaped radiation detection unit 15 in which a tunnel-shaped examination space is formed. The 511 keV pair annihilation photon emitted from the examiner M is detected by the radiation detecting unit 15. Then, the time at which the photon is detected is measured, and when the detection time difference between the two detectors in the radiation detection unit 15 is within a fixed time, it is counted as a pair of pair annihilation photons, and further pair annihilation occurs. It is specified as the position on the straight line of the detector pair that detected the point. The emission data thus obtained is accumulated in the console 6, and the PET image is acquired by performing image reconstruction using the emission data accumulated in the console 6. Then, the acquired PET image is displayed on the display unit 7 and transferred to the server in the hospital via the in-hospital network 8.

このとき、被検者Ｍの乳房および腋窩部は、放射線検出部１５における放射線の検出範囲１９内に配置される必要がある。これを可能とするため、放射線検出部１５により形成される放射線の検出範囲１９が、被検者Ｍの乳房と腋窩部とを配置可能な大きさを有するように、放射線検出部１５のサイズが決定されている。 At this time, the breast and axilla of the subject M need to be arranged within the radiation detection range 19 of the radiation detection unit 15. In order to enable this, the size of the radiation detection unit 15 is set so that the radiation detection range 19 formed by the radiation detection unit 15 has a size in which the breast of the subject M and the axilla can be arranged. It has been decided.

被検者Ｍの乳房および腋窩部を検査するときには、図２に示すように、寝台１４における載置部１１の下方で本体カバー１６の内部に形成された空間２０に、被検者Ｍの腕部が収納される。このとき、核医学診断装置による検査は、１０分程度の時間を要する場合がある。このため、空間２０内には、被検者Ｍの腕部を支持するための腕部支持部材２２が配設される。 When inspecting the breast and axilla of the subject M, as shown in FIG. 2, the arm of the subject M is placed in the space 20 formed inside the main body cover 16 below the placing portion 11 of the bed 14. Parts are stored. At this time, the examination by the nuclear medicine diagnostic apparatus may take about 10 minutes. For this reason, an arm support member 22 for supporting the arm of the subject M is arranged in the space 20.

この腕部支持部材２２は、スポンジ等の柔軟な材料を合成皮革等により包囲した構成を有する。この腕部支持部材２２の大きさや形状は、被検者Ｍの体格や、検査時の被検者Ｍの姿勢等に応じて変更される。なお、必要に応じ、複数の腕部支持部材２２を使用して被検者Ｍの腕部を支持するようにしてもよい。 The arm support member 22 has a structure in which a flexible material such as sponge is surrounded by synthetic leather or the like. The size and shape of the arm support member 22 are changed according to the physique of the subject M, the posture of the subject M at the time of the examination, and the like. If necessary, a plurality of arm support members 22 may be used to support the arm of the subject M.

この核医学診断装置においては、寝台１４における本体カバー１６の側面に、被検者Ｍの腕部を収納可能な空間２０に連通する開口部２１が形成されている。この開口部２１は、寝台１４の載置部１１上の被検者Ｍの側方となる本体カバー１６の側面の両側に形成されている。 In this nuclear medicine diagnostic apparatus, an opening 21 that communicates with the space 20 in which the arm of the subject M can be stored is formed on the side surface of the main body cover 16 of the bed 14. The openings 21 are formed on both sides of the side surface of the main body cover 16 which is lateral to the subject M on the placing portion 11 of the bed 14.

被検者Ｍの乳房および腋窩部を検査するときには、被検者Ｍは、図２に示すように、載置部１１に形成された挿入口１２から本体カバー１６の内部に形成された空間２０に腕を挿入する必要がある。この時、空間２０が閉鎖されたものであれば、被検者Ｍが挿入口１２を介して空間２０に腕部を挿入するときに、空間２０の形状等を認識できないことから、不安を感じる。しかしながら、この核医学診断装置においては、被検者Ｍの腕部を収納する空間２０に連通する開口部２１が形成されていることから、被検者Ｍは空間２０がどのようなものであるか認識することができ、被検者Ｍがこのような不安を感じることはない。 When inspecting the breast and axilla of the subject M, the subject M, as shown in FIG. 2, receives the space 20 formed inside the main body cover 16 from the insertion opening 12 formed in the mounting portion 11. You need to insert your arm into. At this time, if the space 20 is closed, when the subject M inserts his or her arm into the space 20 through the insertion opening 12, the shape or the like of the space 20 cannot be recognized, which makes him feel uneasy. .. However, in this nuclear medicine diagnosis apparatus, since the opening portion 21 communicating with the space 20 for accommodating the arm portion of the subject M is formed, the subject M has what kind of space 20. That is, the subject M does not feel such anxiety.

また、検査中において、挿入口１２から空間２０内に、検査に使用する物品が落下し、あるいは、被検者Ｍの嘔吐物が落下することがある。このような場合においても、空間２０に連通する開口部２１を利用することにより、落下物を容易に除去することが可能となる。 Further, during the examination, an article used for the examination may fall from the insertion opening 12 into the space 20, or a vomit of the subject M may fall. Even in such a case, it is possible to easily remove the falling object by using the opening 21 that communicates with the space 20.

さらに、核医学診断装置による検査中には、被検者Ｍの疲労を軽減し、被検者Ｍの検査部位が移動することを防止するため、空間２０内に被検者Ｍの腕部を支持するための腕部支持部材２２が配設される。この腕部支持部材２２の大きさや形状は、被検者Ｍの体格等に応じて変更する必要がある。このような場合においても、空間２０に連通する開口部２１を利用することにより、被検者Ｍに対応した腕部支持部材２２を空間２０内に設置し、あるいは、被検者Ｍの体格等に対応して、腕部支持部材２２の形状、大きさ、数量等を変更することが可能となる。 Further, during the examination by the nuclear medicine diagnostic device, in order to reduce the fatigue of the subject M and prevent the examination site of the subject M from moving, the arm portion of the subject M is placed in the space 20. An arm support member 22 for supporting is provided. The size and shape of the arm support member 22 need to be changed according to the physique of the subject M and the like.
