Abstract
Description
例えば、検査撮影においては当初の予定とは異なる撮影が行われることもしばしばある。当初1方向のみ撮影する予定だったが、1方向では診断が困難と判断し、撮影時に2方向の撮影に切り替えて追加撮影する場合や、撮影後に医用画像を確認したところ、不備が発見され、再撮影する場合である。上記特許文献1に記載のシステムによれば、このような予定外の撮影によって得られた医用画像は参照テーブルに登録されていないため、別検査のグループにまとめられてしまう。
本来、同じ患者、同じ検査に属する医用画像が別々にまとめられたり、何枚か欠けた状態でまとめられたりすると、左右比較に用いるべき医用画像が欠けるため、病変候補の検出処理の精度低下をもたらす。また、検出結果についても別検査として出力されるため、医師も効率的な読影ができない。
入力された医用画像の付帯情報を用いて、同一患者の同一検査毎に前記入力された医用画像をグループ化して記憶手段に保存する制御手段を備え、
前記制御手段は、新たに医用画像が入力されると、当該入力された医用画像と、既にグループ化が完了した医用画像の付帯情報を照合することによって、前記入力された医用画像が追加撮影又は再撮影によって得られたか否かを判断し、追加撮影又は再撮影によって得られたと判断した場合、前記付帯情報を用いて前記入力された医用画像と前記グループ化が完了した医用画像とを同一患者の同一検査毎に再グループ化する医用画像処理装置が提供される。
前記制御手段は、前記入力された医用画像と前記グループ化が完了した医用画像の患者及び検査の付帯情報が一致し、撮影部位及び撮影方向の付帯情報が不一致だった場合、追加撮影されたと判断し、前記グループ化が完了した医用画像と患者及び検査の付帯情報が一致するグループに、前記入力された医用画像を分類し、再グループ化する請求項1に記載の医用画像処理装置が提供される。
前記制御手段は、前記入力された医用画像と前記グループ化が完了した医用画像の患者、検査、撮影部位及び撮影方向の付帯情報が一致した場合、再撮影されたと判断し、前記グループ化が完了した医用画像であって、前記入力された医用画像と患者、検査、撮影部位及び撮影方向の付帯情報が一致する医用画像を、前記入力された医用画像に置き換えて再グループ化する請求項1又は2に記載の医用画像処理装置が提供される。
前記制御手段は、医用画像が再グループ化されると、当該再グループ化された医用画像をグループ単位で病変候補検出手段に出力する請求項1~3の何れか一項に記載の医用画像処理装置が提供される。
医用画像処理装置による医用画像のグループ化方法であって、
制御手段により、入力された医用画像の付帯情報を用いて、同一患者の同一検査毎に前記入力された医用画像をグループ化して記憶手段に保存する工程と、
制御手段により、新たに医用画像が入力されると、当該入力された医用画像と、既にグループ化が完了した医用画像の付帯情報を照合することによって、前記入力された医用画像が追加撮影又は再撮影によって得られたか否かを判断する工程と、
制御手段により、追加撮影又は再撮影によって得られたと判断した場合、前記付帯情報を用いて前記入力された医用画像と前記グループ化が完了した医用画像とを同一患者の同一検査毎に再グループ化する工程と、
を含む医用画像のグループ化方法が提供される。
コンピュータを、
入力された医用画像の付帯情報を用いて、同一患者の同一検査毎に前記入力された医用画像をグループ化して記憶手段に保存し、
新たに医用画像が入力されると、当該入力された医用画像と、既にグループ化が完了した医用画像の付帯情報を照合することによって、前記入力された医用画像が追加撮影又は再撮影によって得られたか否かを判断し、
追加撮影又は再撮影によって得られたと判断した場合、前記付帯情報を用いて前記入力された医用画像と前記グループ化が完了した医用画像とを同一患者の同一検査毎に再グループ化する制御手段、
として機能させるためのプログラムが提供される。
撮影装置21の撮影方式はカセッテ方式、FPD(Flat Panel Detector)方式の何れであってもよい。カセッテ方式は、揮尽性の蛍光体プレートを内蔵するカセッテを用いる撮影方式であり、撮影毎に撮影者がカセッテを交換し、読取装置22にカセッテを装填して医用画像の読取処理を行わせる必要がある。
コンソール23は、付帯情報が付帯された医用画像を、医用画像処理装置3及び画像サーバ4に出力する。
図2に示すように、医用画像処理装置3は、制御部31、操作部32、表示部33、通信部34、第1記憶部35、第2記憶部36、病変候補検出部37を備えて構成されている。
表示部33はディスプレイを備え、制御部31の表示制御に従って操作画面や医用画像を表示する。
微小石灰化クラスタは、低濃度で略円錐形状の濃度変化を有する微小な画像部分が集合(クラスタ化)した画像として現れる。このような濃度特性に基づき、病変候補検出部37は医用画像に対し、正方形の一定領域毎に3重リングフィルタによるフィルタ処理を行う。3重リングフィルタは濃度変化が理想的な円錐形状を示す場合の濃度勾配の強度成分及び方向成分がベクトルパターンとして設定されたリングフィルタである。周辺から中心にかけて異なるベクトルパターンが設定された3つのリングフィルタから構成される。フィルタ処理により円錐形状に近い濃度変化を有する画像領域が、微小石灰化クラスタの候補領域として検出される。
図5を参照して、医用画像処理装置3により実行されるグループ化処理について説明する。グループ化処理は、病変候補の検出処理の対象となる医用画像を、同一患者の同一検査毎にグループ化する処理である。
図5に示すように、コンソール23又は撮影装置21から医用画像処理装置3に医用画像が入力されると(ステップS1;Y)、制御部31は入力された医用画像を第2記憶部36に保存する(ステップS2)。次いで、制御部31はグループ化完了DB51を検索し、グループ化が完了した医用画像であって患者ID及び検査IDが一致する医用画像の有無を判断する(ステップS3)。
新規検査の画像と判断された場合、制御部31は新規検査DB52を検索し、患者ID及び検査IDの付帯情報が一致するグループ化が未完了の医用画像の有無を判断する(ステップS8)。新規検査DB52に、入力された医用画像と同じ患者ID及び検査IDが登録されており、患者ID及び検査IDが一致する医用画像が有る場合(ステップS8;Y)、制御部31は入力された医用画像の画像番号、患者IDといった付帯情報を新規検査DB52に登録する。また、制御部31は入力された医用画像のグループIDとして、患者ID及び検査IDの付帯情報が一致する医用画像と同じグループIDを、新規検査DB52に登録する。これにより、入力された医用画像は、新規検査DB52において患者ID及び検査IDが一致する医用画像と同じグループに分類され、グループ化される(ステップS9)。
図6に示すように、患者IDが001、検査IDが101の医用画像g1(撮影部位:R、撮影方向:MLO)、医用画像g2(撮影部位:L、撮影方向:MLO)、医用画像g3(撮影部位:L、撮影方向:CC)が、1つのグループ(グループID:a1)に分類されてグループ化完了DB51に登録されている。新規検査DB52には登録されている医用画像が無い。ここへ新たに医用画像G1(患者ID:002、検査ID:102、撮影部位:R、撮影方向CC)が入力されたとする。入力された医用画像G1と、グループ化が完了した医用画像g1、g2、g3とは、患者ID及び検査IDが不一致である。新規検査DB52にも入力された医用画像G1と患者ID及び検査IDが一致する医用画像が登録されていない。よって、入力された医用画像G1は新規のグループ(グループID:b1)に分類されて新規検査DB52に登録される。
図7に示すように、患者IDが002、検査IDが102の医用画像G1、G2が1つのグループ(グループID:b1)に分類されて新規検査DB52に登録されている。ここへ新たに医用画像Gn(患者ID:005、検査ID:106、撮影部位:R、撮影方向MLO)が入力されたとする。入力された医用画像Gnはグループ化完了DB51に登録されている医用画像g1~g3、新規検査DB52に登録されている医用画像G1、G2の何れとも患者ID、検査IDが一致しない。よって、入力された医用画像Gnは新規のグループ(グループID:b2)に分類されて新規検査DB52に登録される。このとき、既に登録されていた医用画像G1、G2とは患者IDが異なる医用画像Gnが新規検査DB52に登録されたので、医用画像G1、G2についてはグループ化が完了したと判断され、図7に示すようにグループ化完了DB51にその登録情報が移動する。
追加撮影と判断された場合、制御部31は入力された医用画像の付帯情報をグループ化完了DB51に登録し、グループ化完了DB51において患者ID及び検査IDが一致する医用画像と同じグループIDを登録する。これにより、入力された医用画像はグループ化が完了した医用画像であって、患者ID及び検査IDが一致する医用画像と同じグループに分類され、再グループ化が行われる(ステップS13)。再グループ化後、本処理を終了する。新たに入力される医用画像が有れば、ステップS1から処理が開始される。
図8に示すように、患者IDが001、検査IDが101の医用画像g1(撮影部位:R、撮影方向:MLO)、医用画像g2(撮影部位:L、撮影方向:MLO)、医用画像g3(撮影部位:L、撮影方向:CC)が、1つのグループ(グループID:a1)に分類されてグループ化完了DB51に登録されている。ここへ新たに医用画像g4(患者ID:001、検査ID:101、撮影部位:R、撮影方向CC)が入力されたとする。入力された医用画像g4とグループ化が完了した医用画像g1、g2、g3とは患者ID及び検査IDが一致するが、撮影部位及び撮影方向は不一致である。よって、入力された医用画像g4は医用画像g1~g3と同じグループID:a1が付与されてグループ化完了DB51に登録される。これにより、グループID:a1のグループが再グループ化される。
再撮影と判断された場合、制御部31は入力された医用画像の付帯情報をグループ化完了DB51に登録し、グループ化完了DB51において患者ID、検査ID、撮影部位及び撮影方向が一致する医用画像と同じグループIDを登録する。次いで、制御部31は入力された医用画像と患者ID、検査ID、撮影部位及び撮影方向が一致する医用画像の付帯情報をグループ化完了DB51から削除する。これにより、入力された医用画像と患者ID、検査ID、撮影部位及び撮影方向が一致する医用画像が、入力された医用画像に置き換えられ、再グループ化される(ステップS14)。再グループ化後、本処理を終了する。新たに入力される医用画像が有れば、ステップS1から処理が開始される。
図9に示すように、患者IDが001、検査IDが101の医用画像g1(撮影部位:R、撮影方向:MLO)、医用画像g2(撮影部位:L、撮影方向:MLO)、医用画像g3(撮影部位:L、撮影方向:CC)、医用画像g4(撮影部位:R、撮影方向:CC)が、1つのグループ(グループID:a1)に分類されてグループ化完了DB51に登録されている。ここへ新たに医用画像g5(患者ID:001、検査ID:101、撮影部位:R、撮影方向CC)が入力されたとする。入力された医用画像g5とグループ化が完了した医用画像g4とは患者ID、検査ID、撮影部位及び撮影方向が一致する。よって、入力された医用画像g5は医用画像g4と置き換えられてグループ化完了DB51に登録される。これにより、グループID:a1のグループが再グループ化される。
これにより、予定通りに撮影されて入力された医用画像を、同一患者の同一検査毎にグループ化することができる。
再グループ化された医用画像はグループ単位で病変候補検出部37に出力され、再処理されるので、病変候補の検出にあたり左右乳房の比較を行うことができ、病変候補の検出処理の精度が向上する。
例えば、上記実施形態では医用画像処理装置3においてグループ化処理を行っていたが、コンソール23や画像サーバ4によってグループ化処理を行ってもよい。コンソール23によってグループ化処理する場合、コンソール23は撮影装置21や読取装置22により生成された医用画像をグループ化し、病変候補検出部37による病変候補の検出処理の対象として、医用画像をグループ単位で医用画像処理装置3に送信する。画像サーバ4によってグループ化処理する場合、画像サーバ4はコンソール23から入力された医用画像をグループ化し、同様にグループ単位で医用画像処理装置3に送信する。何れの場合も追加撮影や再撮影によって再グループ化された場合には、一度送信した医用画像でも、再グループ化されたグループ単位で医用画像を再度送信すればよい。医用画像処理装置3の病変候補検出部37は、送信されたグループ単位の医用画像を用いて病変候補の検出処理を実行する。
図10に示すグループ化処理では、入力された医用画像が新規検査、追加撮影又は再撮影の何れかであるかを判断して、グループ化又は再グループ化した後(ステップS9、S13、S14)、ステップS1の処理に戻る。所定時間経過しても新たに入力される医用画像が無ければ(ステップS1;N、S15;Y)、新規検査DB52からグループ化完了DB51に医用画像の登録情報が移動され(ステップS12)、本処理を終了する。つまり、図10に示すグループ化処理では、新規撮影、追加撮影又は再撮影の何れであっても、所定時間内に入力された同一患者及び同一検査の医用画像群についてグループ化又は再グループ化する。
また、本発明に係るプログラムのデータを通信回線を介して提供する媒体として、キャリアウエーブ(搬送波)も本発明に適用される。
