Description
Technical Field

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a method for displaying a region of interest according to an embodiment of the present invention, which is applicable to displaying a distribution of a specified region of interest in all tomographic images. The method may be performed by a region-of-interest display device, which may be implemented by software and/or hardware, integrated in a device with a display function, such as a desktop computer, a laptop computer, a mobile terminal, and the like. The method specifically comprises the following steps:
and S110, acquiring a plurality of tomographic images of the scanning object, and overlapping and displaying the tomographic images in a preset display area.
The tomographic image may be an image obtained by scanning a scanning target with a scanning device and reconstructing the scanning target from obtained scanning data. The scanning device may be, but is not limited to, an X-ray machine, a CT device and an MR device. The scanning object can be a certain part of a human body or the whole body, and can be determined according to actual conditions and requirements. Illustratively, when a human chest is scanned with a CT apparatus, the obtained tomographic image is an image corresponding to a certain thickness in the human chest. The preset display region may be a region that is set in advance in the display interface and is used for displaying the tomographic image. The area size of the preset display area in the embodiment can be matched with the image size of the tomographic image in real time.
Specifically, after the scan object is scanned, a plurality of tomographic images corresponding to the scan object may be obtained, and the obtained tomographic images may be displayed in a preset display area in a superimposed manner, so that the preset display area may display only one tomographic image at the same time. The present embodiment may take the tissue structure distribution of the scanning object as a stacking order, and sequentially stack all the tomographic images into the preset display area, for example, based on the tissue structure distribution of the scanning object, a tomographic image corresponding to a first tissue structure is taken as a tomographic image of a top layer (i.e., a first layer) in the preset display area, and a tomographic image corresponding to a last tissue structure is taken as a tomographic image of a bottom layer (i.e., a last layer) in the preset display area, so as to more conveniently view a scanning result corresponding to the scanning object.
And S120, segmenting the preset bar-shaped frame according to the total layer number of the fault image, and determining each selected block in the preset bar-shaped frame and the corresponding relation between the fault image and the selected block.
The total number of layers of the tomographic images is equal to the total number of the tomographic images, that is, each layer of the tomographic image only contains one tomographic image. The preset bar frame may refer to one bar region provided at a preset position. The preset position may refer to the upper, lower, left, or right side of the preset display area, which may be set according to user requirements and actual situations. For example, the present embodiment may set the preset bar frame horizontally above or below the preset display area, or may set the preset bar frame vertically on the left or right side of the preset display area. The block selection refers to a block area obtained after the preset bar frame is segmented. The corresponding relation between the tomograms and the selection blocks can be a one-to-one corresponding relation, namely each tomogram uniquely corresponds to one selection block in the preset bar-shaped frame. In other embodiments, the tomograms and the blocks may be in a many-to-one relationship, that is, a plurality of tomograms correspond to the same block. For example, one block may be associated with every 2 tomographic images.
Exemplarily, S120 may include: determining the total layer number of the tomographic image as the number of segmentation sections; segmenting the preset bar-shaped frame according to the number of segmentation segments, and determining each segmented segment as each selected block; and determining the corresponding relation between the tomograms and the blocks according to the superposition sequence of the tomograms and the arrangement sequence of the blocks.
The arrangement sequence of the blocks can be determined according to the front and back positions of each block in the preset bar frame. For example, if the preset bar frame is arranged horizontally, after the preset bar frame is divided into the blocks, the arrangement order of the blocks may be determined from left to right or from right to left, for example, the leftmost block is determined as the first block, and the rightmost block is determined as the last block.
Specifically, the total number of layers n of the tomographic image may be determined as the number of segmentation segments n, that is, the preset bar frame is segmented into n segments, each segment is used as a block, and the number of blocks is ensured to be equal to the total number of layers of the tomographic image, so that each block corresponds to each tomographic image one to one. The embodiment can perform non-uniform segmentation on the preset bar-shaped frame; uniform splitting may also be performed. For example, the present embodiment may non-uniformly divide the preset bar frame according to the importance degree of each tomographic image. For example, the higher the importance degree of the tomographic image, the larger the size of the corresponding block, so that the importance degree of the tomographic image can be determined according to the size of the block. When the size of each block is determined according to the importance degree of each tomographic image, the correspondence between each tomographic image and each block can be established at the same time. The embodiment can also perform uniform segmentation on the preset bar-shaped frame, so that the size of each segmented block after segmentation is the same, and the segmented block can be displayed neatly and conveniently. Fig. 2 shows a schematic diagram of a preset bar frame, as shown in fig. 2, a vertical arrangement of the preset bar frame 1 is provided, and the preset bar frame 1 is evenly divided into 13 blocks 2. The present embodiment can correspond the tomograms and the blocks of the same ordinal number according to the stacking order of the tomograms and the arrangement order of the blocks. For example, the uppermost block in fig. 2 corresponds to a tomographic image of the topmost layer (i.e., the first layer) in the preset display area, and the lowermost block corresponds to a tomographic image of the bottommost layer (i.e., the last layer) in the preset display area, so that the correspondence relationship of each block to the tomographic images can be determined in turn.
S130, determining a first block corresponding to the current region of interest according to the information of the current region of interest and the corresponding relation.
The region of interest refers to a certain region in the tomographic image. For example, if the tomographic image is an image obtained by scanning a chest of a human body, the region of interest may be a region where a skin, a chest cavity, a blood vessel, a heart, a tumor, or the like is located in the tomographic image, and a doctor may set any desired region of interest according to actual situations. One or more interested areas can be preset in the embodiment, and a new interested area can be added in real time according to actual requirements. The current region of interest refers to a region of interest that the user wants to find at the current moment. The present embodiment may use any one of the regions of interest as the current region of interest. The information of the current region of interest may include, but is not limited to, at least one of: the category of the current interested area, the tomography image layer ordinal number corresponding to the current interested area and the identification corresponding to the current interested area. The type of the current region of interest may refer to a name of a location corresponding to the current region of interest, such as skin, chest, blood vessel, heart, or tumor. The identification corresponding to the current region of interest may include, but is not limited to, one of the following indications: color identification, numerical identification, letter identification and character identification. The first block is a block corresponding to the current region of interest among all blocks, that is, a block corresponding to a tomographic image including the current region of interest. The first blocks also change in real time with the switching of the current region of interest, and the number of the first blocks may be one or more.
Illustratively, S130 may include: determining a target image containing the current region of interest in the plurality of tomographic images according to the information of the current region of interest; and determining a first block corresponding to the current region of interest according to the target image and the corresponding relation.
The target image is a tomographic image containing the current region of interest, and can be changed in real time along with the switching of the current region of interest. The number of target images in this embodiment may be one or more. Specifically, the present embodiment may determine, according to the information of the current region of interest, a target image including the current region of interest, and determine, according to the correspondence between the tomographic image and the selected block, the selected block corresponding to each target image as the first selected block. In this embodiment, an interested region category list may be set in the display interface for displaying all the categories of the interested region, so that the user may select an interested region category in the interested region category list through a click operation, and thus an interested region corresponding to the selected category may be used as the current interested region. And if the user adds a new region of interest, adding the category of the new region of interest into the region of interest category list, and updating the region of interest category list.
And S140, displaying the identifier corresponding to the current region of interest in the first selected block.
Wherein, the mark may include but not limited to at least one of color mark, number mark, letter mark and character mark. In this embodiment, the identifiers corresponding to different regions of interest may be the same or different. In an embodiment, only the identifier corresponding to the current region of interest is displayed in the preset bar frame, and the identifiers corresponding to other regions of interest are not displayed at the same time, so that the layer number of the currently selected region of interest can be determined according to the identifier displayed in the current first block when the identifiers corresponding to different regions of interest are the same. If the identifications corresponding to different interesting regions are different, the different interesting regions can be distinguished by using different identifications so that the user can view the interesting regions more intuitively and conveniently.
Specifically, if the identifiers corresponding to different regions of interest are different, the identifier corresponding to the current region of interest may be determined according to the correspondence between the regions of interest and the identifiers. If only one first selection block exists, only the identification corresponding to the current region of interest is directly displayed in the first selection block; if two or more first selection blocks exist, the identification corresponding to the current region of interest can be displayed in each first selection block based on a preset display mode, so that the number of layers of the current region of interest can be visually determined according to the displayed identification, the tomographic image containing the region of interest can be checked more conveniently, and the checking efficiency is improved. Illustratively, the preset display mode may be: and displaying the identifier corresponding to the current region of interest in the determined first block every time the first block is determined, so that the identifiers of the first blocks are displayed one by one. The preset display mode may also be: after all the first selection blocks are determined, the identification corresponding to the current region of interest is displayed in each first selection block at the same time, so that the distribution of the current region of interest in all the tomographic images can be quickly seen by a user.
Exemplarily, if the identifier is only a color identifier, and the identifier corresponding to the current region of interest is red, and a plurality of first tiles are respectively the first tile, the second tile, and the fifth tile in the preset bar frame (from top to bottom) of fig. 2, the first tile, the second tile, and the fifth tile in the preset bar frame are all displayed in red, so that the user can visually determine the distribution of the current region of interest according to the red tiles, that is, determine that three layers of tomographic images including the current region of interest are respectively the first layer, the second layer, and the fifth layer, and do not need to open a detailed page corresponding to the current region of interest, thereby greatly improving the efficiency of searching the number of layers of the region of interest.
It should be noted that, when the operation of switching the current region of interest is detected, steps S130 and S140 are repeatedly executed to change the identifier of the first block to the switched identifier, so that the layer number of each region of interest can be intuitively determined according to the displayed identifier.
According to the technical scheme, the preset bar frame is segmented, the corresponding relation between each tomographic image and the selected block is established, so that the first selected block corresponding to the tomographic image containing the current region of interest can be determined, the first selected block is marked by using the identification corresponding to the current region of interest, the distribution condition of the current region of interest in all tomographic images can be determined more intuitively according to the identification displayed in the preset bar frame, the tomographic image containing the current region of interest can be found out quickly according to the displayed identification, and the viewing efficiency is improved.
On the basis of the above technical solution, determining a target image including a current region of interest from a plurality of tomographic images according to information of the current region of interest may include: and determining the tomograms corresponding to the tomogram sequence number as target images according to the tomogram sequence number corresponding to the current region of interest.
The layer ordinal number of the tomographic image corresponding to the current region of interest refers to a layer ordinal number corresponding to the tomographic image including the current region of interest. The present embodiment can simultaneously acquire region-of-interest information in a tomographic image from a digital Imaging and Communications in medicine file when acquiring the tomographic image of a scanned object. When the tomographic image is displayed, whether the tomographic image of the layer contains the region-of-interest information or not is detected, and if at least one region-of-interest is contained, the region-of-interest contained in the tomographic image is displayed at the same time when the tomographic image is displayed. When the user selects an existing region of interest in the tomogram, the system detects the tomograms to determine the number of sequences of the tomograms including the region of interest. In this embodiment, before the first block is determined, each region of interest may be previously outlined in each tomographic image by using an automatic delineation method or a manual delineation method, so that the tomographic image layer ordinal corresponding to each region of interest may be determined. Specifically, according to the current region of interest, the present embodiment may determine, as the target image, the tomogram corresponding to each tomogram layer ordinal number. On the basis of the above technical solution, determining a target image including a current region of interest from a plurality of tomographic images according to information of the current region of interest may include: and determining a target image containing the current region of interest according to the identifier corresponding to the current region of interest and at least one identifier corresponding to each tomographic image.
Specifically, when the identifiers corresponding to different regions of interest are different, the target image including the current region of interest can be determined according to the identifiers. For example, all regions of interest included in each tomographic image and the identifier corresponding to each region of interest may be predetermined, and then at least one identifier corresponding to each tomographic image may be obtained. The identification corresponding to the current interested area is matched with the identification corresponding to each tomographic image, and if the matching is successful, the tomographic image which is successfully matched is determined to be the target image, so that all target images including the current interested area can be determined.
In an embodiment, the user may also modify or delete an existing region of interest. If the shape of the region of interest is modified, the corresponding block selection identifier is unchanged; if the interesting area is deleted, the corresponding block selection mark disappears.
Example two
Fig. 3 is a flowchart of a method for displaying a region of interest according to a second embodiment of the present invention, and in this embodiment, based on the foregoing embodiment, optimization is performed on "determining a target image including a current region of interest in a plurality of tomographic images according to information of the current region of interest". Wherein explanations of the same or corresponding terms as those of the above-described embodiments are omitted.
Referring to fig. 3, the method for displaying a region of interest provided by the present embodiment includes the following steps:
s210, acquiring a plurality of tomographic images of the scanning object, and displaying the tomographic images in a preset display area in an overlapping manner.
S220, segmenting the preset bar-shaped frame according to the total layer number of the fault images, and determining each selected block in the preset bar-shaped frame and the corresponding relation between the fault images and the selected blocks;
s230, detecting whether the type of the current region of interest exists in the outlined region list, if so, entering the step S240, and if not, entering the step S250.
The outlined region list refers to a list composed of each region of interest category that has been outlined in the tomographic image. For example, if a region of interest classified into skin, chest, blood vessel, and heart has been outlined in the tomographic image, the outlined region list at this time includes skin, chest, blood vessel, and heart.
Specifically, the category of the current region of interest is matched with each category in the outlined region list, and if the matching is successful, it indicates that the category of the current region of interest exists in the outlined region list, that is, the current region of interest is the outlined region of interest, and at this time, the operation of step S240 is executed; if the matching fails, it indicates that the type of the current region of interest does not exist in the outlined region list, that is, the current region of interest is a newly added region of interest, and at this time, the operation of step S250 is executed.
S240, according to the region of interest outlined in advance in each tomographic image, determining the tomographic image containing the current region of interest as a target image, and proceeding to step S260.
When acquiring a tomographic image of a scanning object, the present embodiment may already use an automatic delineation manner or a manual delineation manner to delineate each region of interest in the tomographic image; after acquiring the tomographic image of the scanning object and before S230, the region of interest in the tomographic image may be contoured in an automatic or manual manner.
Specifically, when the current region of interest is a delineated region of interest, the region of interest delineated in advance in each tomographic image and the current region of interest may be subjected to category matching to detect whether each tomographic image includes the current region of interest, and the tomographic image successfully matched is determined as a target image including the current region of interest.
And S250, outlining the tomographic image containing the current region of interest in a manual outlining mode or an automatic outlining mode, and determining the tomographic image containing the current region of interest as a target image.
Specifically, when the current region of interest is a newly added region of interest, the current region of interest in the tomographic image may be manually or automatically contoured in real time in a manual or automatic manner, and the tomographic image including the current region of interest is determined as the target image, so that the new region of interest may be added to the tomographic image.
In this embodiment, when the current region of interest is outlined, if the identifiers corresponding to different regions of interest are different, the current region of interest in the tomographic image can be quickly identified according to the identifiers. For example, if the identifier corresponding to the current region of interest is red, the current region of interest in the tomographic image may be outlined by using a red line. If the identifier corresponding to the current region of interest is a digital identifier, the digital identifier can be displayed on a line outlining the current region of interest, so that different regions of interest in the same tomographic image can be distinguished. For example, if two regions of interest, a first region of interest and a second region of interest, exist in a certain tomographic image, and the identifier corresponding to the first region of interest is red and the identifier corresponding to the second region of interest is blue, when the identifier displayed in the first block is blue, it indicates that the region of interest outlined by a blue line in the tomographic image is the current region of interest, so that which region of interest in the tomographic image is the current region of interest can be quickly identified, and the identification efficiency is improved.
Illustratively, after the step of outlining the tomographic image containing the current region of interest, the method further comprises the following steps: and adding the category of the current region of interest into the outlined region list so as to update the outlined region list in real time.
And S260, determining a first selected block corresponding to the current region of interest according to the target image and the corresponding relation.
And S270, displaying the identifier corresponding to the current region of interest in the first selected block.
It should be noted that when the user views the current region of interest in a certain tomographic image, the shape of the outline of the current region of interest may be modified, and at this time, the identifier displayed by the selected block corresponding to the tomographic image may not change. If the user completely erases the sketched shape, the mark displayed by the selected block corresponding to the tomogram correspondingly disappears.
According to the technical scheme, whether the current region of interest is a outlined region of interest or a newly added region of interest can be determined more conveniently according to the type of the current region of interest, so that when a user wants to check the currently unmasked region of interest, the new region of interest in a tomographic image can be manually outlined or automatically outlined in real time, and the checking experience of the user is improved.
On the basis of the above technical solution, after S260, the method may further include: determining the selected blocks except the first selected block as second selected blocks in all the selected blocks; and displaying the preset area identification in the second selection block.
And the sectional image corresponding to the second selected block does not contain the current region of interest. The preset area mark is preset and is used for representing a display mark corresponding to a tomographic image which does not contain the current region of interest. Illustratively, the preset region identifier may be a color identifier, a number identifier, a letter identifier, or a text identifier different from the identifier corresponding to the current region of interest, such as a transparent color.
Specifically, the mark corresponding to the current region of interest is displayed in each first block, and the preset region mark is displayed in each second block, so that which tomographic image contains the current region of interest and which tomographic image does not contain the current region of interest can be distinguished more obviously, and the viewing experience of a user is improved.
On the basis of the technical scheme, the method further comprises the following steps: and when the preset slide block in the preset bar frame moves to the current selection block, determining the image to be displayed corresponding to the current selection block according to the corresponding relation, and displaying the image to be displayed in the preset display area.
The preset sliding block is a preset square block which can move in the preset bar-shaped frame, so that the page turning function of the tomographic image is realized. The current selection block is a selection block corresponding to a tomographic image which is desired to be displayed in a preset display area at the current moment. The image to be displayed refers to a tomographic image corresponding to the current selected block.
Specifically, the preset display area in this embodiment can only display one layer of tomographic image, so that the user can switch the tomographic image displayed in the preset display area by moving the preset slider in the preset bar frame, that is, the page turning function of the tomographic image is realized. In the embodiment, the movement of the preset slider in the preset bar frame can be controlled by using a mouse or a touch mode, when the preset slider slides to the current selection block, it is indicated that a tomographic image corresponding to the current selection block, that is, an image to be displayed, needs to be displayed, at this time, the image to be displayed corresponding to the current selection block can be determined according to the corresponding relationship between the tomographic image and the selection block, and the image to be displayed is displayed in the preset display area. The embodiment can also be used for quickly positioning and displaying the corresponding tomographic image by directly clicking the current selection block or other selection blocks based on the clicking operation of the user, so that the viewing efficiency of the tomographic image is further improved.
