- a screen 60e in FIG. 3 (e) shows a screen display example displayed after measurement at three different locations of the blood vessel 71.
- Each of the three range cursors 81-1, 81-2, and 81-3 is displayed.
- result labels 82-1, 82-2, and 82-3 are connected and displayed. Since the range cursor 81-1 and the result label 82-1 are the same as the range cursor 81 and the result label 82 displayed on the screen 60d, they are drawn using the same identification information “A”. .
- the cursor processing unit 34 displays the result labels 82-1, 82-2, and 82-3, and stores information related to the range cursor 81 in the cursor information storage unit 35.
- the range cursor information 90 is information for identifying the medical image in which the range cursor 81 is set (corresponding to “medical image number”), the type of the range cursor 81, and the position of the range cursor. Information (for example, coordinates of the start point and end point), identification information of the range cursor 81 (corresponding to “identification name”), measurement result, time when the range cursor 81 is set (corresponding to “time stamp”), etc. Information regarding the range cursor 81 is stored in the cursor information storage unit 35.

Is generated. Then, instead of the separated result label 82, the identification label 83 is connected to the end point of the range cursor 81 and displayed. The display position of the identification label 83 is fixed to the end point of the range cursor 81, but the separated result label 82 can be moved to an arbitrary position in the image display area 62.
- the screen 60f in FIG. 3 (f) is separated from the range cursor 81-1 by dragging the result label 82-1 with the mouse cursor 80 (in FIG. 3 (f), the moving direction is indicated by a one-dot chain line).
- the result label 83-1 is connected and displayed at the end point of the range cursor 81-1.
- the screen 60f only the result label 82-1 is separated, but the other result labels 82-2 and 82-3 can be separated and displayed in the same manner as the result label 82-1.
- Step S105 The separated result labels are displayed in alignment (S105).
- the aligning unit 36 refers to the range cursor information 90 and preliminarily enters the aligning unit 36.
- the result label 82 separated from the range cursor 81 is aligned with reference to the set predetermined alignment condition, and the cursor processing unit 34 displays the aligned result label 82.
- the aligning unit 36 when arranging in “time series order”, substitutes the time stamp of the range cursor 81 as the set time of the result label 82.
- the “arrangement order” is, for example, the x coordinate of the result label 82 connected to the range cursor 81 when scanned along one direction of the screen, such as from the top to the bottom and from the left to the right. Alternatively, it means that the y-coordinates are arranged in ascending or descending order.
- the coordinates of the result label 82 substitute the end point coordinates of the range cursor 81.
- Alignment display has a mode in which each of the separated labels is displayed in the order of alignment and a mode in which the separated labels are collectively displayed in one frame.
- a frame in which a plurality of labels are displayed together is referred to as a label box.
- FIG. 6A is an example of the former, and the three separated result labels 82-1, 82-2, and 82-3 are individually and according to the “arrangement order” along the initial y coordinate. Shows the state of alignment display.
- FIG. 6B is an example of the latter.
- Three separated result labels 82-1, 82-2, and 82-3 are accommodated in one label box 84, and “identification name” is displayed. Are arranged in order. Thereby, it is possible to prevent the visibility from being lowered due to the scattered result labels 82-1, 82-2, 82-3.
- the label box 84 Selecting any result label in the label box 84 aligns the selected result label and the split label box containing the result label aligned below it, above the selected result label
- the label box can be divided into a divided label box including the result label. That is, the label box 84 can be divided at the position of the selected result label.
- the result label 82-1 has been selected and moved.
- the label boxes 84 below the result label 82-1 (corresponding to the entire label box 84 in this example) can be moved together.
- the result label 82-2 is selected and moved.
- the label box 84 includes a divided label box 84b below the result label 82-2 and a divided label box 84a positioned above the result label 82-2 (a label box including only the result label 82-1). And only the divided label box 84b can be moved. Generation, display, and division processing of these label boxes 84 are executed by the cursor processing unit 34.
- the result labels 82-1, 82-2, and 82-3 can be viewed together, and the desired labels can be moved together, improving operability. .
- the result labels set for each branch branch can be displayed together, and the result labels and label boxes that suit the operator's preference can be displayed.
- the display positions of the aligned result labels 82-1, 82-2, 82-3 and the label box 84 may be configured to be displayed in a predetermined area on the screen. For example, it may be determined to display at the upper left of the screen.
- an area in which a subject is not imaged in a medical image (hereinafter referred to as “external area”). ) May be configured to display the aligned labels.
- FIG. 8 shows an example of the region outside the subject. In the ultrasonic image 100, the non-field-of-view region 101 (see FIG.
- the detection of the aperture region 121 is equipped with a position detection unit, such as an encoder, for detecting the position of the X-ray aperture in the X-ray apparatus, and the non-subject region detection unit 37 is based on an output signal from the encoder.
- the aperture region 121 may be detected by calculating the coordinates of the aperture region on the medical image.
- 8A, 8B, and 8C show examples in which the label box 84 is displayed in the region outside the subject. However, instead of the label box 84, aligned result labels may be arranged. good.
- the cursor processing unit 34 acquires the coordinates of the non-subject region on the medical image from the non-subject region detection unit 37, and converts the coordinates into coordinates on the screen. Then, the aligned result labels are displayed in alignment on the area outside the subject on the screen.
- the visibility of the peripheral part of the measurement range can be improved by displaying the result label separately from the measurement range. Furthermore, since the identification label is fixed and displayed on the range cursor indicating the measurement result when the result label is separated, the correspondence between the identification information in the identification label and the identification information in the result label becomes clear, It becomes easy to grasp which part of the range cursor indicates the measurement result of the result value of the result label.
- the separated result labels can be displayed in alignment according to a predetermined rule, the visibility of the result labels is improved. Further, when displaying in an aligned manner, by displaying in the region outside the subject, it is possible to avoid a problem that the diagnostic label of the medical image is hindered by the result label being displayed overlapping the diagnostic region.

Abstract
Description
本実施形態は、カーソル処理部34が、操作部50(第一操作部)で計測範囲の指定を受け付けた場合に、範囲カーソルを表示し、計測部38による計測が終了した場合に範囲カーソルの一端点に結果ラベルを連結して表示し、操作部(第二操作部)で結果ラベルの移動操作を受け付けた場合に、その移動操作に追従して結果ラベルを範囲カーソルから分離して表示するとともに、結果ラベルが連結されていた範囲カーソルの一端点に識別ラベルを表示する、という基本動作に加えて、整列部36が、範囲カーソルから分離された結果ラベルを、所定の整列条件に従って整列する、ことが特徴である。
画像選択・表示制御部33は、表示対象となる医用画像を画像記憶部32から読み出したり、通信I/F39を介して画像DB3から取得したりして、表示部40の画面上に表示する(S101)。図3の(a)は、本ステップにおける画面表示例を示す。図3の(a)の画面60aには、ソフトボタンが表示されるボタン領域61と、医用画像が表示される画像表示領域62と、が含まれる。画面60aでは、画像表示領域62に、血管71が撮像された医用画像70が表示されている。ボタン領域61には、計測開始を指示入力するための「計測」ボタン61aと、結果ラベルの整列を指示入力するための「整列」ボタン61bと、が含まれる。
表示された医用画像上において、物理量の計測を行う対象となる計測範囲を設定する(S102)。本実施形態では、血管71の血管幅(距離)を計測する処理を例に挙げて説明する。
計測範囲の終点が入力されると、計測部38は、範囲カーソル81で指定された計測範囲の距離計測を行い、カーソル処理部34は、計測結果を含む結果ラベルを生成・表示する(S103)。本実施形態では、操作者が、マウスカーソル80を終点に移動し、終点位置の入力動作(例えば、マウスクリック)を行なうと、カーソル処理部34が、その入力動作をトリガーとして、範囲カーソル81の終点に結果ラベル82を連結して表示する処理を実行する。図3の(d)の画面60dは、範囲カーソル81に、結果ラベル82を連結して表示した状態を示す。なお、計測範囲の終点位置の入力後は、マウスカーソル80を範囲カーソル81から独立させ、医用画像70上の任意の位置に移動することができる。
結果ラベル82を切り離す(S104)。例えば、操作者が切り離し対象となる結果ラベル82の選択動作(例えばマウスクリック)を行い、その結果ラベルを移動する動作(例えばドラッグ)を行なう。カーソル処理部34は、結果ラベル82を範囲カーソル81の端点から切り離すと同時に、図4の(b)に示すように、種別アイコン82a及び識別情報82bを含み、かつ計測結果を含まない識別ラベル83を生成する。そして、切り離された結果ラベル82の代わりに、範囲カーソル81の端点に識別ラベル83を連結して表示する。識別ラベル83の表示位置は、範囲カーソル81の端点に固定されるが、切り離された結果ラベル82は、画像表示領域62の任意の位置に移動させることができる。
切り離した結果ラベルを整列表示する(S105)。操作者が、切り離された結果ラベルを整列させるための入力操作(例えば、図6の整列ボタン61bをクリック)を行なうと、整列部36は、範囲カーソル情報90を参照し、予め整列部36に設定された所定の整列条件を参照して、範囲カーソル81から切り離されている結果ラベル82を整列し、カーソル処理部34が整列後の結果ラベル82を表示する。整列条件として、結果ラベル82が付与された順序に沿った「時系列順」、「識別名順」(アルファベット順に付す場合には、アルファベット順など)、結果値の昇順又は降順からなる「結果値順」、または結果ラベル82の「配置順」(座標順)などがある。
本実施形態は、カーソル処理部34が、操作部50(第一操作部)で計測範囲の指定を受け付けた場合に、範囲カーソルを表示し、前記計測部による計測が終了した場合に前記範囲カーソルの一端点に前記結果ラベルを連結して表示するという基本動作に加えて、計測範囲の端点を指示する端点カーソルを更に表示することが特徴である。
画像選択・表示制御部33は、計測対象となる医用画像を読み出して、表示部40の画面上に表示する(S201)。図12の(a)に示す画面160aは、本ステップ終了時の画面表示例を示す。画面160aには、ソフトボタンが表示されるボタン領域61と、医用画像が表示される画像表示領域62と、が含まれる。画面160aでは、画像表示領域62に血管71が撮像された医用画像70が表示されている。また、ボタン領域61には、計測開始を指示入力するための「計測」ボタン61aが含まれる。
計測範囲の始点を入力する(S202)。以下、血管71の血管幅を計測する処理を例に挙げて説明する。操作者は、操作部50を操作してマウスカーソル80を計測範囲の始点、すなわち、血管71のうち、計測対象となる血管幅の一端部に移動し、位置入力操作(例えばクリック動作)を行なう(S202)。
カーソル処理部34は、図12の(b)の画面160bに示すように、マウスカーソル80の先端に端点カーソル85-1の先端部を合わせて医用画像70上に重畳表示する(S203)。このときの端点カーソル85-1の向きは、初期設定された方向に表示される。画面160bでは、端点カーソル85-1の中心線が、画面の左右方向と平行になる向きで表示される。
計測範囲全体の範囲指定を行なう(S204)。操作者が操作部50を介してマウスカーソル80の移動を開始すると、カーソル処理部34は、端点カーソル85-1を非表示に変更し、かつ、マウスカーソル80の移動の軌跡を、始点を一端とする線分を用いて表示する。カーソル処理部34は、この線分を用いて範囲カーソル81を生成、表示する。操作者は、マウスカーソル80を計測範囲の終点まで移動させる操作を行なう。図12の(c)の画面160cは、本ステップの終了時における画面表示例を示す。
計測範囲の終点を入力すると、計測範囲の計測が行われ、結果ラベルが表示される(S205)。本実施形態では、操作者が、マウスカーソル80を終点に移動し、終点位置の入力動作(例えば、マウスクリック)を行なうと、計測部38が範囲カーソル81で指定された線分の距離を計測する。そして、カーソル処理部34が、上記距離計測の結果値を含む結果ラベル82を生成し、範囲カーソル81の終点に連結して表示する。図12の(d)の画面160dは、本ステップの終了時における画面表示例を示す。画面160dに表示された範囲カーソル81に結果ラベル82が連結された状態、すなわち、確定モードで範囲カーソル81が表示されているが、この確定モードでは、範囲カーソル81の始点、終点位置の再設定などの編集作業は行なえない。
範囲カーソル81の始点及び終点が、計測対象領域の端部の位置からずれていると、正確な計測結果が得られない。その場合、範囲カーソル81の始点又は終点の位置を、再設定する必要が生じる。そこで、操作者が、範囲カーソル81の始点又は終点位置の再設定の要否を判断し、必要であれば、ステップS207へ進み、不要であれば処理を終了する。
計測範囲の再設定を行なう範囲カーソルを選択する(S207)。この選択は、例えば、図12の(e)の画面160eに示すように、計測範囲の再設定の対象となる範囲カーソル81にマウスカーソル80を合わせて選択動作(例えば、マウスクリック)をすることにより行なえる。このマウスによる選択動作は、表示の切替であるとともに機能の切替でもある。
カーソル処理部34は、範囲カーソル81を確定モードから編集モードに表示切替を行なう。すなわち、結果ラベル82を非表示にし、範囲カーソル81の両端点に端点カーソル85-1、85-2を連結して表示する(S208)。図12の(f)の画面160fは、編集モードに切り替わった範囲カーソル81を示す。
端点カーソルが表示されている編集モードでは、操作者が、端点カーソル85-1又は85-2の位置を変更し、範囲カーソル81の端点の位置を変更する(S209)。本ステップの処理を、図13を用いて説明する。
範囲カーソルの表示モードを、編集モードから確定モードに変更する(S210)。操作者は、操作部50を介してモード切替操作(例えば、編集モードの範囲カーソル81の一部をマウスクリック)を行う。カーソル処理部34は、端点カーソル85を非表示にするとともに、計測部38は、新たに設定された範囲カーソル81の物理量を計測する。カーソル処理部34は、その計測結果を含む結果ラベル82を生成し、表示する。再度、編集モードに変更する必要がある場合には(S211)、ステップS206に戻る。
本実施形態は、計測モードや医用画像撮像装置の撮影の種別に応じた範囲カーソルの形状や付加的なカーソルを追加することが特徴である。計測モードには、例えば管腔や臓器の径を計測する場合に最短距離を計測するモード(最短距離計測モード)、内径を計測するモード(内側計測モード)、外径を計測するモード(外側計測モード)などが含まれる。これら計測モードに適したカーソル形状や新たなカーソルが作成、表示される。計測モードの選択は、操作部を介して受け付けることができる。
本実施形態は、確定モード(範囲カーソルに結果ラベルが連結された表示モード)と編集モード(範囲カーソル及び端点カーソルが表示された表示モード)とを切替可能な実施形態(第二実施形態)の画像表示装置において、さらに範囲カーソルの端点から所定の領域にある範囲カーソル上の領域を、上記表示モード切替操作の対象として選択することを禁止する選択禁止領域に設定する機能を付加したものである。
