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 scanning range determining method according to an embodiment of the present invention, where this embodiment is applicable to a case of accurately determining a scanning range of image scanning, and the method may be executed by a scanning range determining apparatus, where the scanning range determining apparatus may be implemented by software and/or hardware, and the scanning range determining apparatus may be configured on a computing device, and specifically includes the following steps:
and S110, acquiring a target scanning area and a human body area map of the object to be scanned.
For example, the object to be scanned may be an object to be scanned, such as a human body, an animal, a body part of the human body or the animal, or an area containing a plurality of body parts. The target scanning area may be an area where an image of a subject to be scanned is scanned, and may be, for example, an abdominal area, a chest area, a head area, a knee area, or the like.
The human body region map can be an image showing various features of the human body, such as images showing various joints of the human body; it is also possible to obtain a partial body region, for example the head and neck region, or a human anatomical map, depending on the object to be scanned. The human body region is illustrated schematically with reference to fig. 2, which shows various features of the human body.
Therefore, the scanning range of the object to be scanned is determined based on the acquired target scanning area and human body area map of the object to be scanned.
And S120, determining the position of the target feature corresponding to the target scanning area based on the target scanning area and the human body area map.
For example, the target feature may be a feature corresponding to the target scanning area determined based on the target scanning area and the body region map. For example, taking a human body region map as an example of a human body feature map labeled with human body features, the target features may be features corresponding to the target scanning region determined based on the target scanning region and the human body region map.
Based on the target scanning area and the human body area map, a target feature (such as a human body joint) corresponding to the target scanning area can be determined, and according to the position of the target feature, namely according to the target scanning area to be scanned, the specific position of the target scanning area in the human body area map between which joints is determined. In this way, the target scanning area can be transferred to the target joint, so that the scanning range of the object to be scanned can be determined based on the target joint.
And S130, determining the position of a starting scanning line and the position of an ending scanning line for scanning the object to be scanned based on the target feature and the target scanning area.
For example, the start scan line and the end scan line may be scan lines at both ends of the scan range. According to the target characteristics (such as human body joints) and the target scanning area, based on preset rules, the position of a starting scanning line and the position of an ending scanning line for scanning an object to be scanned can be determined, so that the scanning range of the object to be scanned can be determined based on the position of the starting scanning line and the position of the ending scanning line, the problem that in the prior art, the code value of a starting scanning bed and the code value of an ending scanning bed in the scanning range need to be determined manually is solved, the scanning range of the object to be scanned can be automatically determined by utilizing the human body characteristics and the target scanning area, and the effect of efficiently and accurately determining the scanning range is achieved.
Optionally, a corresponding relationship between the target scanning area and the target feature is preset; the determining, based on the target feature and the target scanning area, a position of a start scanning line and a position of an end scanning line for scanning the object to be scanned may specifically be: determining the position of a starting scanning line and the position of an ending scanning line for scanning the object to be scanned based on the corresponding relation between the target scanning area and the target characteristics; and adjusting the position parameter of the starting scanning line and/or the position parameter of the ending scanning line based on the difference between the scanning area formed by the starting scanning line and the ending scanning line and the target scanning area.
For example, the correspondence between the target scanning object and the target feature may be: if the target scanning area of the object to be scanned is a chest area, the scanning range needs to include all the chest areas when scanning the chest of the object, so that the corresponding area in the human body area diagram can be an area between two features of L3 and C5 in fig. 2, and the position of the target feature is the position of two features of L3 and C5 in fig. 2. For another example, if the target scanning region of the object to be scanned is an abdomen region, when the abdomen of the object is scanned, the scanning range needs to include all the abdomen regions, so that the corresponding region in the human body region diagram may be a region between the two features of Hip and L3 in fig. 2, and the position of the target feature is the position of the two features of Hip and L3 in fig. 2.
According to the corresponding relationship between the target scanning area and the target feature, the starting scanning line and the ending scanning line for scanning the object to be scanned can be determined, for example, taking the target scanning area of the object to be scanned as the chest area, the determined target features are two features L3 and C5 in fig. 2, and then the starting scanning line and the ending scanning line are respectively determined as two features L3 and C5.
The position parameter of the start scan line may be parameter information describing a position of the start scan line. Also, the position parameter of the end scan line may be parameter information describing the position of the end scan line.
According to the difference between the scanning area formed by the determined start scanning line and the target scanning area formed by the determined end scanning line, the position parameter of the start scanning line and/or the position parameter of the end scanning line can be adjusted, for example, taking the target scanning area of the object to be scanned as the head area, the determined target joint is two characteristics of C5 and Cranium in fig. 2, but since the whole head area of the human body needs to be included when the head area is scanned, and the Cranium characteristic is located at the vertex position, if the position of the start scanning line is determined at the Cranium characteristic (C5 is the position of the end scanning line), the scanning area formed by the start scanning line and the end scanning line is the area between the two characteristics of C5 and Cranium, so that the whole head area cannot be completely scanned, and therefore, the position of the start scanning line needs to be based on the Cranium characteristic, after moving a certain distance up the foot-head direction, as the position of the starting scan line (as shown by the dashed line ab above the crank feature in fig. 2). However, if the dashed line ab is taken as the position of the starting scan line, the position parameter of the starting scan line cannot be accurately described, so it needs to be described by means of the position of the Cranium feature, i.e. the position of the Cranium feature relative to X is the position of the starting scan line, for example, the position 2mm above the Cranium feature is taken as the position of the starting scan line, i.e. the position parameter of the starting scan line to be determined relative to the target feature.
Note that here, the start scan line may be drawn at C5, and the end scan line may be drawn at Cranium. And then according to the target scanning area and user requirements, whether the position parameters of the starting scanning line and/or the ending scanning line need to be adjusted or not is judged.
Note that except that the description of the scan line is described as being at Xmm above/below a certain feature point. It can also be described as: from feature 1 to feature 2, where x is adjustable, for example, taking the target scanning area of the object to be scanned as the face area, the target features determined are both C5 and Cranium in fig. 2, since Cranium is at the top, when scanning the face of the object to be scanned, the starting scanning line (C5 is the position of the ending scanning line) needs to be determined between C5 and Cranium without expanding into the C5 and Cranium areas, as shown by the dashed line cd in fig. 2, the dashed line cd can be described as a position 20% between the Cranium and C5 features, that is, the dashed line cd is near the Cranium feature and 20% between the Cranium and C5 features.
Therefore, the scanning range of the object to be scanned can be accurately determined based on the corresponding relation between the target scanning area and the target characteristic and the target scanning area.
And S140, scanning the object to be scanned based on the position of the starting scanning line and the position of the ending scanning line.
Illustratively, the position parameters of the starting scanning line and the position parameters of the ending scanning line are imported into a scanning protocol of the object to be scanned, and the object to be scanned can be scanned based on the scanning protocol.
Specifically, the position parameter of the start scanning line and the position parameter of the end scanning line are imported into the scanning protocol of the object to be scanned, and may be that after the position parameter of the start scanning line and the position parameter of the end scanning line are determined, that is, after the start scanning line and the end scanning line are completely drawn in the human body region map, the position parameter of the start scanning line and the position parameter of the end scanning line are imported into the scanning protocol of the object to be scanned by clicking an "OK" button in fig. 2. Thus, the object to be scanned can be accurately scanned based on the accurately determined scanning range.
Optionally, the scanning the object to be scanned based on the position of the start scanning line and the position of the end scanning line may specifically be: adding the position parameters of the starting scanning line and the position parameters of the ending scanning line to the scanning protocol of the object to be scanned; and scanning the object to be scanned based on the scanning protocol.
For example, the determined position parameter of the start scan line and the position parameter of the end scan line may be added to a scan protocol of the object to be scanned, and the object to be scanned is scanned based on the scan protocol.
Optionally, the scanning the object to be scanned based on the scanning protocol may be: performing initial scanning on an object to be scanned, and determining the corresponding relation between each characteristic of the object to be scanned and a bed code value of a scanning bed based on the initial scanning result; determining the actual position of the starting scanning line and the actual position of the ending scanning line of the object to be scanned based on the corresponding relation between the position of the starting scanning line and the position of the ending scanning line in the scanning protocol and the bed code value of the scanning bed and the characteristics of the object to be scanned; and scanning the object to be scanned based on the actual position of the starting scanning line and the actual position of the ending scanning line.
For example, after an object to be scanned lies on a scanning bed, an initial scan may be performed on the object to be scanned to obtain an initial scan image of the object to be scanned, and a correspondence between each feature of the object to be scanned and a bed code value of the scanning bed may be determined, specifically, the correspondence between each feature and the bed code value of the scanning bed may be determined according to a pixel value of each pixel in the initial scan image. In the initial scanning image, the pixel value of each pixel point can represent a bed code value, so that the corresponding relation between each feature and the bed code value of the scanning bed can be obtained by using the initial scanning image, and the actual position of the initial scanning line and the actual position of the ending scanning line of the object to be scanned are determined.
Based on the corresponding relationship between the position of the start scanning line and the position of the end scanning line in the scanning protocol and the corresponding relationship between the features of the object to be scanned and the bed code value of the scanning bed, the actual position of the start scanning line and the actual position of the end scanning line for scanning the object to be scanned, that is, the bed code value of the start scanning line and the bed code value of the end scanning line for scanning the object to be scanned, can be determined. The scanning range of the object to be scanned can be determined based on the bed code value of the starting scanning line and the bed code value of the ending scanning line, and the object to be scanned can be purposefully scanned based on the scanning range. Therefore, the scanning range of the object to be scanned can be accurately determined based on all the characteristics, the problem of manual adjustment of the scanning range in the prior art is solved, and the effect of efficiently and accurately determining the scanning range is achieved.
According to the technical scheme of the embodiment of the invention, the target scanning area and the human body area image of the object to be scanned are obtained, and the target characteristic corresponding to the target scanning area is determined based on the target scanning area and the human body area image, so that the target scanning area can be switched to the target characteristic, and the scanning range of the object to be scanned can be determined based on the target characteristic. Based on the target characteristics and the target scanning area, the position of a starting scanning line and the position of an ending scanning line for scanning the object to be scanned are determined, so that the scanning range of the object to be scanned is determined based on the position of the starting scanning line and the position of the ending scanning line, the problem that in the prior art, the value of a starting scanning bed code and the value of an ending scanning bed code of the scanning range need to be determined manually is solved, the scanning range of the object to be scanned can be automatically determined by utilizing a human body area map and the target scanning area, and the effect of efficiently and accurately determining the scanning range is achieved. And scanning the object to be scanned based on the position of the starting scanning line and the position of the ending scanning line, so that the object to be scanned can be accurately scanned based on the accurately determined scanning range.

And responding to an operation instruction of human body features in the human body region map, and updating the human body region map based on the operation instruction; wherein the operation instruction comprises: deleting the human body features in the human body area map, adding the human body features in the human body area map, and editing the human body features in the human body area map.
As shown in fig. 3, the method of the embodiment of the present invention specifically includes the following steps:
s210, acquiring a target scanning area and a human body area map of the object to be scanned.
And S220, calling a human body area map marked with human body characteristics, and displaying the human body area map.
For example, after the target scanning area of the object to be scanned is determined, the human body area map marked with the human body features may be directly called, specifically, for example, an operation of opening the human body area map by clicking on a computer terminal may trigger a call instruction for calling the human body area map, and based on the call instruction, the human body area map may be directly called and displayed on a display device such as a screen. This is done in order to visually determine target features based on the target scan area in the body region map, based on which the start scan line and the end scan line are drawn.

For example, the operation instruction may be an instruction for operating a human body feature in a human body region diagram, and may be at least one of deleting the human body feature in the human body region diagram, adding the human body feature in the human body region diagram, and editing the human body feature in the human body region diagram. Updating the human body area map can be realized based on the operation instruction responding to the human body features in the human body area map.
Specifically, the deleting of the human body features in the human body region map may be, for example: taking the feature of deleting the "Hip" in fig. 2 as an example, the user (physician) may select the "delete feature" by pointing the mouse at the "Hip" font or the "Hip" feature, and right-clicking the mouse to display a menu bar with the "delete feature" font, so as to delete the "Hip" feature from the human body region map.
Similarly, human features are added to the human body region map, and may be, for example: adding a feature between the "Hip" feature and the "Upper Knee" feature in fig. 2, calibrating the mouse at the position of the feature to be added between the "Hip" feature and the "Upper Knee" feature in fig. 2, right-clicking the mouse to display a menu bar, wherein the word "add feature" is arranged in the menu bar, and selecting the "add feature", namely adding the feature to be added between the "Hip" feature and the "Upper Knee" feature.
Editing the human body features in the human body region map, for example, may be: taking editing of the "Hip" feature in fig. 2 as an example, if it is found that the position of the "Hip" feature needs to be adjusted, the mouse may be calibrated on the "Hip" font or the "Hip" feature, and the "Hip" font or the "Hip" feature may be adjusted by clicking the mouse and dragging the "Hip" font or the "Hip" feature.
It should be noted that the above example is only a specific example of deleting, adding and editing the human body features in the human body region map, and specific gesture operations, voice operations, and the like may be implemented to delete, add and edit the human body features in the human body region map, and are not described in detail here. Any operation that can delete the human body features in the human body region map, add the human body features in the human body region map, and edit the human body features in the human body region map is within the protection scope of the embodiment of the present invention.
It should be noted that step S230 is only executed when the user needs to modify the body region map, and if the user does not need to modify the body region map, the user may choose not to execute step S230.
Therefore, the change of the human body area diagram is realized by responding to the operation instruction of the human body characteristics in the human body area diagram according to the user requirements, the user requirements are greatly met, and the user experience is improved.
And S240, determining the position of the target feature corresponding to the target scanning area based on the target scanning area and the human body area map.
And S250, determining the position of a starting scanning line and the position of an ending scanning line for scanning the object to be scanned based on the target feature and the target scanning area.
And S260, scanning the object to be scanned based on the position of the starting scanning line and the position of the ending scanning line.
