Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
It should be noted that the medical imaging apparatus mentioned in the background art may be an ultrasound imaging apparatus, and may also be any other suitable medical imaging apparatus such as a magnetic resonance imaging apparatus, an X-ray tomography apparatus, a positron emission tomography apparatus, and the like. The present application takes an ultrasound imaging apparatus as an example for illustration, and the protection scope of the present application is not limited.
In one embodiment, referring to fig. 1a, the present application provides a method for editing a medical image annotation, comprising the steps of:
and S110, acquiring an annotation editing instruction corresponding to the annotation in the current medical image in the medical image group.
The medical image group refers to a group of medical images displayed by a medical imaging device, the medical image group comprises at least two medical images, and the medical images refer to internal tissue images obtained by imaging, processing and the like on a human body or a part of the human body in a non-invasive manner. The current medical image refers to a medical image which is in an edited state and is of interest to the user. Each medical image in the medical image group is displayed with an annotation at the same relative position. The relative position refers to a position determined by the annotation relative to a certain reference position in the medical image, for example, if the reference position is a vertex at the upper left corner of the medical image, the position of the annotation in the medical image can be determined according to the relative position of the annotation and the vertex at the upper left corner of the medical image. The annotation refers to an image, a character, a symbol, or the like attached to the medical image, and is used to explain which part or pathological feature of a region in the medical image, such as a fetal head, a fetus, or the like. A comment editing instruction refers to an instruction that can trigger a comment editing state. For example, the comment editing instruction may be moving in or out of a mouse, clicking of a mouse or inputting of a keyboard, long-time pressing of a comment area on a touch screen, or clicking of an area outside a comment on a touch screen.
Specifically, the medical imaging device displays at least two medical images, the at least two medical images can form a medical imaging group, and each medical image in the medical imaging group displays an annotation at the same relative position. And if the user is interested in a certain medical image in the medical image group, determining that the interested medical image is the current medical image. The current medical image is displayed with annotations, and when the annotations on the current medical image need to be edited, annotation editing instructions corresponding to the annotations in the current medical image are obtained.
Illustratively, referring to fig. 1b, the ultrasound imaging device includes a touch screen 110 and a main display screen 120. The touch screen 110 displays a first ultrasound image 130 and the main display 120 displays a second ultrasound image 140. The first ultrasound image 130 and the second ultrasound image 140 are displayed with annotations at the same relative position, for example, the first ultrasound image 130 and the second ultrasound image 140 display "fetal head" at a first relative position, and the first ultrasound image 130 and the second ultrasound image 140 display "fetal" at a second relative position. When the second ultrasound image 140 is in the interesting state, i.e. the second ultrasound image 140 is used as the current medical image, and the "fetal head" annotation on the second ultrasound image 140 needs to be edited, the "fetal head" annotation in the second ultrasound image 140 receives a mouse click operation or a keyboard operation.
It is understood that the first image 130 and the second ultrasound image 140 can display the same content, for example, the first image 130 and the second ultrasound image 140 can simultaneously display the same fetal image or various sectional images of the same internal organs of the human body. The images displayed by the first image 130 and the second image 140 may be different. For example, the first image 130 may display an image of the entire fetus, while the first image 140 may display an image of a part of the head of the fetus, or a limb of the fetus, etc.
It should be noted that a part of the medical images in the medical image group may be displayed on the touch screen, and the rest of the medical images may be displayed on the main display screen. Such as the touch screen 110, displays the first ultrasound image 130 and the main display 120 displays the second ultrasound image 140. The medical image group may be displayed on only the touch screen or the main display screen, for example, the first image 130 and the second ultrasound image 140 may be simultaneously displayed on the touch screen 110, and the first image 130 and the second ultrasound image 140 may also be simultaneously displayed on the main display screen 120. Referring to fig. 1c, two medical images, which are enlarged medical images and thumbnails, are displayed on the main display 120.
And S120, displaying an input cursor corresponding to the annotation editing instruction on the annotation in the current medical image according to the annotation editing instruction.
The input cursor may be a symbol in the shape of an arrow, a vertical line, a horizontal line, or the like, for identifying an insertion position where the comment is to be written. Specifically, when an annotation editing instruction corresponding to an annotation in the current medical image is acquired, the annotation editing instruction triggers an event corresponding to the annotation, so that the input cursor position corresponding to the annotation in the current medical image is determined according to the triggered event. The input cursor position refers to an insertion position for specifying an input character when the comment in the current medical image receives a trigger operation by the user. Then, at the input cursor position, the annotation in the current medical image displays the corresponding input cursor.
Illustratively, referring to fig. 1d, the "fetal head" annotation generates an input cursor "I" corresponding to the annotation editing instructions at the input cursor position corresponding to the "fetal head" annotation. Specifically, when the mouse is moved into the frame corresponding to the "fetal head" annotation in the current medical image, the keyboard may be used to select the insertion position of the input character, that is, the annotation editing instruction corresponding to the "fetal head" annotation in the current medical image is obtained. Events that may be triggered by the annotation editing instructions may be used to determine the corresponding input cursor position, such as the position between the "head" and "section". Then, an "I" type cursor appears at a position between the "head" and the "section", the position of the "I" type cursor representing an insertion position of a character to be input, i.e., an input cursor position corresponding to the "fetal head" annotation.
And S130, synchronously displaying the input cursor corresponding to the annotation editing instruction on the annotations in the same relative position in each medical image except the current medical image.
The medical imaging device displays at least two medical images which can form a medical imaging group, and each medical image in the medical imaging group displays an annotation at the same relative position. The annotations in the current medical image display the input cursor at the corresponding input cursor position, and the annotations in each medical image except the current medical image in the medical image group can synchronously display the corresponding input cursor according to the input cursor position corresponding to the annotations in the current medical image.
Illustratively, referring to fig. 1b, the touch screen 110 displays a first ultrasound image 130, the main display 120 displays a second ultrasound image 140, and the "fetal head" annotation in the first ultrasound image 130 and the second ultrasound image 140 displays an input cursor "I" at the same position. For example, referring to fig. 1c, the main display 120 displays two medical images, which are enlarged medical images and thumbnails. The magnified medical image, the "fetal head" annotation in the thumbnail, are also displayed with the input cursor "I" at the same location.
In the embodiment, an annotation editing instruction corresponding to an annotation in a current medical image in a medical image group is obtained; then, according to the annotation editing instruction, displaying an input cursor corresponding to the annotation editing instruction on the annotation in the current medical image; and finally, synchronously displaying the input cursors corresponding to the annotation editing instruction in the annotations in each medical image except the current medical image in the medical image group, so that the medical image equipment is provided with at least two input cursors, and a user can edit the corresponding annotations in each medical image displaying the input cursors, thereby solving the technical problem that the user can only edit the annotations attached to the medical images on a touch screen or a main display screen.
In one embodiment, the input cursors corresponding to the annotation editing instruction in the current medical image include a first input cursor and a second input cursor, and the first input cursor is preset to be transparent and colorless so that the first input cursor is invisible. The annotation corresponds to a control, and the first input cursor is an input cursor of the control corresponding to the annotation in default setting. After the current medical image acquires the annotation editing instruction, the control corresponding to the annotation in the current medical image can acquire the corresponding input focus, and a first input cursor is displayed when the focus is acquired. The second input cursor may be implemented in a control manner, the second input cursor is unrelated to the control corresponding to the annotation, the second input cursor is a control having a display style similar to that of the first input cursor, and the second input cursor does not have a partial function of the first input cursor, for example, the position where the annotation editing instruction occurs may be obtained by the first input cursor, but the position where the annotation editing instruction occurs may not be obtained by the second input cursor.
Because the control corresponding to the annotation in the current medical image is set with the first input cursor by default. In order to avoid the first input cursor of the control from influencing the presentation effect of the second input cursor, the first input cursor is preset to be transparent and colorless so as to enable the first input cursor not to be visible. The control corresponding to the annotation can be a text box control, and the CaretBrush attribute of the text box control can be set to be Transparent, so that the color of the first input cursor of the text box control corresponding to the annotation is changed to be colorless, and the effect of hiding the first input cursor is achieved. Further, the position where the annotation editing instruction occurs is obtained through the first input cursor, and then the second input cursor is generated at the position where the annotation editing instruction occurs, so that the effect of simulating the first input cursor by using the second input cursor is achieved.
Referring to fig. 2, according to the annotation editing instruction, the displaying of the annotation in the current medical image by the input cursor corresponding to the annotation editing instruction includes:
and S210, determining a first input cursor position corresponding to the annotation in the current medical image according to the annotation editing instruction.
And S220, displaying a second input cursor corresponding to the annotation editing instruction on the current medical image at the position of the first input cursor corresponding to the annotation.
In each medical image except the current medical image, the annotations in the same relative position synchronously display an input cursor corresponding to the annotation editing instruction, and the input cursor comprises:
and S230, synchronously displaying a second input cursor corresponding to the annotation editing instruction in the annotations in the same relative position in each medical image except the current medical image according to the first input cursor position corresponding to the annotation in the current medical image.
When the annotation editing instruction corresponding to the annotation in the current medical image is acquired, the annotation editing instruction triggers an event corresponding to the annotation, so that the position of a first input cursor corresponding to the annotation in the current medical image is determined according to the triggered event. Then, since the first input cursor is hidden as being transparent and colorless, at the first input cursor position, the annotation in the current medical image displays the corresponding second input cursor.
Specifically, the medical imaging device displays at least two medical images, the at least two medical images can form a medical imaging group, and each medical image in the medical imaging group displays an annotation at the same relative position. The annotation in the current medical image has a first input cursor and a second input cursor at the corresponding input cursor position, and the first input cursor is transparent, colorless and hidden, so that the annotation in the current medical image presents only one input cursor, namely the second input cursor at the corresponding input cursor position.
The control corresponding to the annotation in the current medical image can obtain the corresponding input focus, and a first input cursor is displayed when the focus is obtained. The first input cursor is not visible to the user because it is transparent and colorless. Further, a first input cursor position corresponding to an annotation in the current medical image can be determined through an event triggered by the annotation editing instruction, so that the position of an annotation display input cursor in each medical image except the current medical image can be determined according to the first input cursor position corresponding to the annotation in the current medical image, and then a second input cursor is displayed at the position.
In this embodiment, the first input cursor with the default annotation is hidden, and the position for displaying the input cursor is obtained according to the first input cursor, so that the second input cursor is displayed at the obtained position, and finally, the effect that each medical image in the medical image group displays the input cursor is achieved.
In one embodiment, each annotation located at the same relative position in each medical image is formed as an annotation group corresponding to the medical image group. Referring to fig. 3, before obtaining an annotation editing instruction corresponding to an annotation in a current medical image in the medical image group, the method further includes the following steps:
s310, whether the comment group in the editing state exists in the medical image group is detected.
And S320, if the comment group does not exist, starting the editing state of the comment group corresponding to the comment editing instruction in the medical image group.
And S330, if so, judging whether the comment group in the editing state is the same as the comment group corresponding to the comment editing instruction.
And S340, if the two comments are the same, receiving a comment editing instruction by the comment group in the editing state.
And S350, if the two annotation groups are different, exiting the editing state of the annotation group in the editing state, and opening the editing state of the annotation group corresponding to the annotation editing instruction in the medical image group.
Illustratively, taking an ultrasound imaging device as an example, the touch screen 110 displays the first ultrasound image 130, and the main display 120 displays the second ultrasound image 140. The ultrasound imaging device displays two annotation sets, the "fetal head" and the "fetus", respectively. The annotation in the second ultrasound image 140 can be moved in and out by responding to the movement of the mouse cursor, and the switch of the annotation editing state is controlled, that is, the mouse cursor is moved in the region corresponding to the annotation, the annotation enters the editing state, the region corresponding to the annotation is moved out, and the annotation exits the editing state.
When the "fetal head" annotation in the second ultrasound image 140 enters an edit state change, it may be detected whether there is an annotation group in the edit state in the first ultrasound image 130 and the second ultrasound image 140. If not, the edit status of the "fetal head" annotation group is turned on. If yes, judging whether the annotation group in the editing state is the same as the 'fetal head' corresponding to the annotation editing instruction. If the same, for example, the "fetal head" annotation in the first ultrasound image 130 is in the editing state, the annotation editing instruction of the "fetal head" annotation group is received, that is, the "fetal head" annotation in the second ultrasound image 140 is also in the editing state. If the difference is not the same, for example, the "fetus" annotation in the first ultrasound image 130 is in the editing state, the editing state of the "fetus" annotation group in the editing state is exited, and the editing state of the "fetus head" annotation group is turned on. Further, the corresponding annotation group is notified in an event mode, thereby ensuring that the editing states of the same group of annotations in the first ultrasound image 130 and the second ultrasound image 140 are synchronized. It should be noted that, one annotation group may be allowed to enter the editing state at the same time, and when a certain group of annotations enters the editing state, the editing state of the annotation group originally in the editing state may be exited.
In the embodiment, whether the annotation group in the editing state exists in the medical image group or not is detected, and when a certain annotation group enters the editing state, the annotation group in the editing state can quit editing, so that one annotation group can be allowed to be in the editing state at the same time.
In one embodiment, referring to fig. 4, the determining of the first input cursor position corresponding to the annotation in the current medical image according to the annotation editing instruction by the text box control corresponding to the annotation comprises the following steps:
s410, obtaining input position coordinates corresponding to the annotation editing instruction through a SelectionChanged event of the textbox control.
And S420, calculating the relative coordinate of a first input cursor corresponding to the annotation editing instruction and the textbox control through a GetRefFromCharacterIndex function according to the input position coordinate.
And S430, determining the relative coordinate as a first input cursor position corresponding to the annotation in the current medical image.
Among them, a TextBox (TextBox) control is generally used for text editing for acquiring text input by a user or displaying text. The TextBox control has the functions of displaying multiple lines, changing the text to conform to the size of the control, and adding basic formatting. SelectionChanged event and GetRecectrFromCharacterIndex function are provided by the TextBox control. The selectechanged event is used to obtain input position coordinates when acquiring a comment editing instruction. The GetRecectrFromCharacterIndex function is used to calculate the relative coordinates of the first input cursor and the text box control after obtaining the input position coordinates.
Specifically, when an annotation editing instruction corresponding to an annotation in a current medical image is acquired, the annotation editing instruction triggers a selectorchanged event of the textbox control, and an input position coordinate corresponding to the annotation editing instruction is acquired through the selectorchanged event. Then, according to the input position coordinate corresponding to the annotation editing instruction, the text box control corresponding to the annotation can calculate the relative coordinate of the first input cursor and the text box control through a GetRecommacterIndex function. Thereby determining the relative coordinate as the first input cursor position corresponding to the annotation in the current medical image.
In one embodiment, referring to fig. 5, according to a first input cursor position corresponding to an annotation in a current medical image, in each medical image except the current medical image, an annotation in the same relative position synchronously displays a second input cursor corresponding to an annotation editing instruction, including the following steps:
and S510, obtaining relative coordinates of the annotations in the same relative position in each medical image except the current medical image in an event mode.
And S520, synchronously displaying a second input cursor corresponding to the annotation editing instruction at the same relative position of the annotation in the relative coordinates of each medical image except the current medical image.
Specifically, when an annotation editing instruction corresponding to an annotation in a current medical image is acquired, the annotation editing instruction triggers a selectorchanged event corresponding to the annotation, and an input position coordinate corresponding to the annotation editing instruction is acquired through the selectorchanged event. Then, according to the input position coordinate corresponding to the annotation editing instruction, the text box control corresponding to the annotation can calculate the relative coordinate of the first input cursor and the text box control through a GetRecommacterIndex function. The obtained relative coordinates are notified to the annotations in each medical image other than the current medical image by an event mode. And finally, synchronously displaying a second input cursor corresponding to the annotation editing instruction on the annotations in each medical image except the current medical image at the relative coordinate position of the first input cursor and the text box control.
Illustratively, taking an ultrasound imaging device as an example, the touch screen 110 displays the first ultrasound image 130, and the main display 120 displays the second ultrasound image 140. The ultrasound imaging device displays two annotation sets, the "fetal head" and the "fetus", respectively. The annotation in the second ultrasound image 140 can be moved into and out of the editing state by responding to the movement of the mouse cursor, and the switch of the editing state of the annotation is controlled, that is, the mouse cursor moves into the area corresponding to the annotation, and the annotation enters the editing state. The corresponding first input cursor position, e.g., a position between the "head" and "section", may be determined by an event triggered by the annotation editing instruction. And obtaining the position information of the first input cursor through a SelectionChange event of the textbox control. After the latest first input cursor position is obtained by the "fetal head" annotation on the second ultrasound image 140, the relative coordinates of the first input cursor and the text box control are calculated by the text box control getectrfromcharacterindex function, and then the second input cursor is drawn at the relative coordinates of the text box control. The same set of "fetal head" annotations on the first ultrasound image 130 acquire relative coordinates by way of an event, and the "fetal head" annotations on the first ultrasound image 130 likewise draw the second input cursor at the relative coordinates of the text box control.
In this embodiment, the annotations in each medical image except the current medical image obtain the relative coordinates in an event mode. Therefore, the second input cursor corresponding to the annotation editing instruction is synchronously displayed on the relative coordinates of the annotations in each medical image except the current medical image, the technical problem that the medical imaging equipment only provides one input cursor at the same time is solved, the input cursor is displayed on the annotation in each medical image in the medical image group, and the effect that the user can simultaneously edit the annotation attached to the medical image through the touch screen or the main display screen of the medical imaging equipment is further realized.
In one embodiment, please refer to fig. 6, after obtaining the relative coordinates by the event mode for the annotation at the same relative position, the method further includes the following steps:
s610, judging whether the annotation in the current medical image and the annotation in each medical image except the current medical image belong to the same annotation group.
At the relative coordinates in each medical image except the current medical image, the annotations in the same relative position synchronously display a second input cursor corresponding to the annotation editing instruction, and the method comprises the following steps:
and S620, if the two images are the same, synchronously displaying a second input cursor corresponding to the annotation editing instruction on the annotations in the same relative position at the relative coordinates in each medical image except the current medical image.
Specifically, when an annotation editing instruction corresponding to an annotation in a current medical image is acquired, the annotation editing instruction triggers a selectorchanged event corresponding to the annotation, and an input position coordinate corresponding to the annotation editing instruction is acquired through the selectorchanged event. Then, according to the input position coordinate corresponding to the annotation editing instruction, the text box control corresponding to the annotation can calculate the relative coordinate of the first input cursor and the text box control through a GetRecommacterIndex function. The annotation in each medical image other than the current medical image obtains the relative coordinates by way of an event. And judging whether the annotation in the current medical image and the annotation in each medical image except the current medical image belong to the same annotation group. And if so, synchronously displaying a second input cursor corresponding to the annotation editing instruction on the annotations in each medical image except the current medical image at the relative coordinates of the first input cursor and the text box control.
Illustratively, taking an ultrasound imaging device as an example, the touch screen 110 displays the first ultrasound image 130, and the main display 120 displays the second ultrasound image 140. The ultrasound imaging device displays two annotation sets, the "fetal head" and the "fetus", respectively. The annotation in the second ultrasound image 140 can be moved into and out of the editing state by responding to the movement of the mouse cursor, and the switch of the editing state of the annotation is controlled, that is, the mouse cursor moves into the area corresponding to the annotation, and the annotation enters the editing state. The corresponding first input cursor position, e.g., a position between the "head" and "section", may be determined by an event triggered by the annotation editing instruction. And obtaining the position information of the first input cursor through a SelectionChange event of the textbox control. After the latest first input cursor position is obtained by the "fetal head" annotation on the second ultrasound image 140, the relative coordinates of the first input cursor and the text box control are calculated by the text box control getectrfromcharacterindex function, and then the second input cursor is drawn at the relative coordinates of the text box control. The relative coordinate of the "fetal head" annotation on the first ultrasound image 130 is obtained through an event, whether the "fetal head" annotation on the first ultrasound image 130 and the "fetal head" annotation on the second ultrasound image 140 belong to the same annotation group is judged, and if the "fetal head" annotation on the first ultrasound image 130 and the "fetal head" annotation on the second ultrasound image 140 belong to the same annotation group, the "fetal head" annotation on the first ultrasound image 130 draws a second input cursor at the relative coordinate of the first input cursor and the text box control.
In one embodiment, referring to fig. 7a, the method further comprises the following steps:
and S710, editing the displayed content of the annotation in the current medical image by receiving the input annotation content.
And S720, synchronously editing the content displayed by the annotation in each medical image except the current medical image in the medical image group according to the received annotation content.
Specifically, when the annotation editing instruction corresponding to the annotation in the current medical image is acquired, the annotation in each medical image in the medical image group synchronously displays the second input cursor corresponding to the annotation editing instruction. The user inputs the content to be displayed in the text box corresponding to the annotation in the current medical image, the text box control corresponding to the annotation receives the input annotation content, and the content displayed by the annotation in the current medical image is edited by receiving the input annotation content. When the displayed content of the annotation in the current medical image changes, the annotation in each medical image except the current medical image is notified in a variable binding mode, and because the annotation in each medical image in the medical image group forms an annotation group, the displayed content of the annotation in each medical image except the current medical image can be synchronously updated according to the received annotation content.
Illustratively, referring to fig. 7b, taking the ultrasound imaging apparatus as an example, the touch screen 110 displays the first ultrasound image 130, and the main display 120 displays the second ultrasound image 140. The ultrasound imaging device displays two annotation groups, the "fetal head" and the "fetus", respectively. After entering the editing state, the user may enter a "section" in the text box corresponding to "fetal head" in the second ultrasound image 140. Referring to fig. 7c, the displayed content, i.e., "fetal head", is updated in the second ultrasound image 140 in synchronization with the "fetal head" annotation in the first ultrasound image 130.
In the embodiment, the content displayed by the annotation in the current medical image is edited by receiving the input annotation content, so that the content displayed by the annotation in each medical image except the current medical image in the medical image group can be synchronously edited according to the received annotation content, the synchronous editing of the annotation in each medical image in the medical image group is realized, the operation flow of the medical image equipment is simplified, and good use experience is brought to a user.
In one embodiment, referring to fig. 8a, the present application provides a method for editing a medical image annotation, which is described by taking an ultrasound imaging apparatus as an example, and includes the following steps:
s811, whether the comment group in the editing state exists in the medical image group is detected.
Referring to fig. 8b, the touch screen 110 displays the first ultrasound image 130, and the main display 120 displays the second ultrasound image 140. The ultrasound imaging device displays two annotation sets, the "fetal head" and the "fetus", respectively. The annotation in the second ultrasound image 140 can be moved in and out by responding to the movement of the mouse cursor, and the switch of the annotation editing state is controlled, that is, the mouse cursor is moved in the region corresponding to the annotation, the annotation enters the editing state, the region corresponding to the annotation is moved out, and the annotation exits the editing state.
When the "fetal head" annotation in the second ultrasound image 140 enters an edit state change, it may be detected whether there is an annotation group in the edit state in the first ultrasound image 130 and the second ultrasound image 140.
And S812, if the current medical image does not exist, starting the editing state of the annotation group corresponding to the medical image group, and acquiring an annotation editing instruction of the current medical image in the medical image group.
If not, the edit status of the "fetal head" annotation group is turned on. If the comment group exists, it is determined whether or not the comment group in the edited state is identical to the "fetal head" corresponding to the comment editing command. If the same, for example, the "fetal head" annotation in the first ultrasound image 130 is in the editing state, the editing state of the "fetal head" annotation group is turned on, i.e., the "fetal head" annotation in the second ultrasound image 140 is also in the editing state. If the difference is not the same, for example, the "fetus" annotation in the first ultrasound image 130 is in the editing state, the editing state of the "fetus" annotation group in the editing state is exited, and the editing state of the "fetus head" annotation group is turned on.
S820, obtaining input position coordinates corresponding to the annotation editing instruction through the SelectionChanged event of the textbox control.
The annotation in the ultrasound imaging device corresponds to the TextBox control by which the selectechanged event is provided. When the annotation is in an editing state, a frame is added on the periphery of the annotation to distinguish the annotation from non-editing annotations. The "fetal head" annotation is a style of the edited state, and the "fetal" annotation is a style of the unedited state. Annotating the input cursor of the corresponding TextBox control includes a first input cursor and a second input cursor, the first input cursor being preset to be transparent and colorless to make the first input cursor invisible. Setting a virtual second input cursor to simulate the first input cursor. Specifically, the annotation corresponds to a TextBox control, and the first input cursor is an input cursor set by default to the TextBox control. After the current medical image obtains the annotation editing instruction, the TextBox control in the current medical image can obtain a corresponding input focus, and the input focus corresponds to the position for displaying the first input cursor. The position of the input cursor of the textbox control may be changed due to the input of the keyboard, the click of the mouse, and the like, for example, when the mouse is used to click the "fetal head" annotation in the second ultrasound image 140, the latest position information of the input cursor, that is, the input position coordinate, may be obtained through a selectorchanged event of the textbox control. It is to be understood that although the first input cursor is hidden and invisible, the first input cursor is an input cursor set by the TextBox control by default, and the input position coordinates can be obtained by the first input cursor designation.
S830, calculating the relative coordinates of a first input cursor corresponding to the annotation editing instruction and the text box control through a GetRecommacterIndex function according to the input position coordinates, and determining the relative coordinates as the position of the first input cursor corresponding to the annotation in the current medical image.
When the mouse clicks the "fetal head" annotation in the second ultrasound image 140, the TextBox control corresponding to the "fetal head" annotation can calculate the relative coordinates of the first input cursor and the TextBox control through the getreffromchacterindex function according to the input position coordinate corresponding to the mouse click. And determining the relative coordinates of the first input cursor and the text box control as the first input cursor position corresponding to the annotation in the current medical image.
And S840, displaying a second input cursor corresponding to the annotation editing instruction on the current medical image at the position of the first input cursor corresponding to the annotation.
When the mouse clicks on the "fetal head" annotation in the second ultrasound image 140, the TextBox control corresponding to the "fetal head" annotation in the second ultrasound image 140 is set with the first input cursor by default. In order to avoid the first input cursor of the TextBox control from affecting the presentation effect of the second input cursor, the first input cursor is preset to be transparent and colorless so that the first input cursor is invisible. Meanwhile, in order to ensure the display effect, a second input cursor is generated at the position of the first input cursor by means of a control, and the second input cursor has the same appearance as the first input cursor, so that the "fetal head" annotation in the second ultrasound image 140 displays the annotation editing instruction, i.e. the corresponding second input cursor is clicked by a mouse.
And S850, obtaining relative coordinates of the annotations in the same relative position in each medical image except the current medical image in an event mode.
When the "fetal head" annotation in the second ultrasound image 140 receives a mouse click, the TextBox control corresponding to the "fetal head" annotation can calculate the relative coordinates of the first input cursor and the TextBox control through the getrectifromchacterindex function according to the input position coordinate corresponding to the mouse click. The relative coordinates are obtained by way of an "fetal head" annotation in the event mode first ultrasound image 130.
S860, judging whether the annotation in the current medical image and the annotation in each medical image except the current medical image belong to the same annotation group.
The "fetal head" annotation on the first ultrasound image 130 obtains the relative coordinates of the first input cursor and the text box control through the event, and determines whether the "fetal head" annotation on the first ultrasound image 130 and the "fetal head" annotation on the second ultrasound image 140 belong to the same annotation group.
And S870, if the two images are the same, synchronously displaying the second input cursor corresponding to the annotation editing instruction at the same relative position of the annotation in the relative coordinates of each medical image except the current medical image.
If the "fetal head" annotation on the first ultrasound image 130 belongs to the same annotation group as the "fetal head" annotation on the second ultrasound image 140, the "fetal head" annotation on the first ultrasound image 130 likewise renders the second input cursor at the relative coordinates of the first input cursor and the text box control.
And S880, editing the displayed content of the annotation in the current medical image by receiving the input annotation content.
The "fetal head" annotation on the second ultrasound image 140 is in the edited state, and the "head" annotation on the second ultrasound image 140 is displayed as "fetal head I" if the "head" word is deleted.
And S890, synchronously editing the content displayed by the annotation in each medical image except the current medical image in the medical image group according to the received annotation content.
Referring to fig. 8b, the displayed content of the "fetal head" annotation on the second ultrasound image 140 becomes "fetal head I", and the "fetal head" annotation on the first ultrasound image 130 is notified by means of the binding variable, so that the "fetal head" annotation on the first ultrasound image 130 is also displayed as "fetal head I".
Referring to fig. 8c, three medical images are displayed on the main display 120, the three medical images are respectively marked as a first medical image 810, a second medical image 820 and a third medical image 830, and the first medical image 810, the second medical image 820 and the third medical image 830 respectively correspond to different scales. When the word "part" in the "fetal head" annotation in the first medical image 810 is deleted, the "fetal head" annotation in the first medical image 810 shows "fetal head I", and the "fetal head" annotations in the second medical image 820 and the third medical image 830 both show "fetal head I".
In this embodiment, although the second input cursor does not have the attribute corresponding to the first input cursor, the annotation can obtain the corresponding focus through the first input cursor. The technical problems that the annotations in the medical image group cannot simultaneously display the input cursor and the annotations corresponding to the medical image group cannot be simultaneously edited in the traditional technology are solved by combining the first input cursor and the second input cursor. The ultrasonic image equipment provided by the implementation reserves a commonly adopted main display screen as an operation area and is matched with a touch screen to edit annotations. Moreover, through reasonable interface layout, an annotation editing area is divided in the touch screen, and the advantages that the operation flow is simple and visual and the operation is easy to operate in the annotation editing process of the touch screen are exerted.
