Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all structures related to the present invention.

Example 1

FIG. 1 is a flowchart of a method for determining a scanning range provided by Embodiment 1 of the present invention. This embodiment can be applied to the situation of accurately determining the scanning range of image scanning. The method can be executed by a scanning range determining device. The scanning range determining device It can be implemented by software and/or hardware, and the scanning range determining apparatus can be configured on a computing device, and specifically includes the following steps:

S110. Acquire a target scanning area and a human body area map of the object to be scanned.

Exemplarily, the object to be scanned may be an object to be scanned by an image, for example, a human body, an animal, a human body or a body part of an animal, or an area including multiple body parts, and the like. The target scanning area may be an area where the object to be scanned needs to be image-scanned, for example, may be an abdomen area, a chest area, a head area, a knee area, and the like.

The human body region map can be an image showing various features of the human body, such as an image showing each joint of the human body; it can also be a part of the human body region obtained from the object to be scanned, such as the head and neck region, or a human anatomy map. Referring to the schematic diagram of the human body region diagram described in FIG. 2 , various features of the human body are shown in the diagram.

In this way, the scanning range of the to-be-scanned object is subsequently determined based on the acquired target scanning area and the human body area map of the to-be-scanned object.

S120. Based on the target scanning area and the human body area map, determine the position of the target feature corresponding to the target scanning area.

Exemplarily, the target feature may be a feature corresponding to the target scanning region determined based on the target scanning region and the human body region map. For example, taking the human body region map as a human body feature map marked with human body features as an example, the target feature here may be a feature 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, the target features (such as human joints) corresponding to the target scanning area can be determined. According to the position of the target features, the target scanning area can be determined according to the target scanning area to be scanned in the human body area map. between which joints are located. 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 subsequently determined based on the target joint.

S130. Based on the target feature and the target scanning area, determine the position of the start scan line and the position of the end scan line for scanning the object to be scanned.

Exemplarily, the start scan line and the end scan line may be scan lines at both ends of the scan range. According to the target features (such as human joints) and the target scanning area, based on preset rules, the position of the start scan line and the position of the end scan line for scanning the object to be scanned can be determined, so as to be based on the position and end of the start scan line. The position of the scanning line determines the scanning range of the object to be scanned, which solves the problem of manually determining the starting scanning bed code value and the ending scanning bed code value of the scanning range in the prior art. The scanning range of the object to be scanned is automatically determined, and the effect of efficiently and accurately determining the scanning range is realized.

Optionally, the corresponding relationship between the target scan area and the target feature is preset; the position of the start scan line and the end scan of the object to be scanned are determined based on the target feature and the target scan area. The position of the line may specifically be: based on the corresponding relationship between the target scanning area and the target feature, determine the position of the start scan line and the position of the end scan line for scanning the object to be scanned; According to the difference between the scan area formed by the start scan line, the end scan line and the target scan area, the position parameter of the start scan line and/or the position parameter of the end scan line is adjusted.

Exemplarily, the corresponding relationship between the target scan object and the target feature may be: if the target scan area of the object to be scanned is the chest area, when scanning the chest, the scan range needs to include all the chest areas, so in the human body area The corresponding area in the figure may be the area between the two features L3 and C5 in FIG. 2 , and the position of the target feature is the position where the two features L3 and C5 in FIG. 2 are located. For another example, if the target scanning area of the object to be scanned is the abdomen area, when scanning the abdomen, the scanning range needs to include all the abdomen areas, so the corresponding areas in the human body area map may be Hip and L3 in FIG. 2 . In the area between the two features, the position of the target feature is the position of the Hip and L3 features in Figure 2.

According to the corresponding relationship between the target scanning area and the target features, the starting scan line and the end scanning line for scanning the object to be scanned can be determined. Two features L3 and C5 in 2, then the start scan line and the end scan line are set at the two features L3 and C5 respectively.

The position parameter of the starting scan line may be parameter information describing the position of the starting scan line. Likewise, 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 scan area formed by the determined start scan line and the end scan line and the target scan area, the position parameter of the start scan line and/or the position parameter of the end scan line can be adjusted, for example, according to the object to be scanned. The target scanning area is the head area as an example. The determined target joints are the two features of C5 and Cranium in Figure 2. However, when scanning the head area, the entire head area of the human body needs to be included, and The Cranium feature is located at the top of the head. If the position of the start scan line is set at the Cranium feature (C5 is the position of the end scan line), the scan area formed by the start scan line and the end scan line is C5 and Cranium. The area between the features, so that the entire head area cannot be scanned completely. Therefore, the position of the starting scan line needs to be moved up a certain distance along the foot-head direction on the basis of the Cranium feature as the starting scan. The position of the line (dashed line ab above the Cranium feature in Figure 2). However, if the dotted line ab is used 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 the position of the Cranium feature, that is, it is described as the position relative to X of the Cranium feature. For the position of the starting scan line, for example, the position at 2 mm above the Cranium feature can be used as the position of the starting scan line, that is, the position parameter of the starting scan line relative to the target feature to be determined.

It should be noted that the start scan line can also be drawn at C5, and the end scan line can be drawn at Cranium. Then, according to the target scanning area and user requirements, it is determined whether the position parameters of the starting scan line and/or the ending scan line need to be adjusted.

It should be noted that, except that the scanning line is described as being Xmm above/below a certain feature point. It can also be described as: the x% position between feature 1 and feature 2, where x is adjustable. For example, taking the target scanning area of the object to be scanned as the face area as an example, the determined target feature is There are two features of C5 and Cranium. Since Cranium is at the top of the head, when scanning the face of the object to be scanned, do not expand to the area of C5 and Cranium, you need to determine the starting scan line between C5 and Cranium (C5 is the end scan line) The position of the line), the dashed line cd in Figure 2, the dashed line cd can be described as the 20% position between the Cranium and C5 features, that is, the dashed line cd is close to the Cranium feature, 20% between the Cranium and C5 features at the location.

In this way, the scanning range of the object to be scanned can be accurately determined based on the corresponding relationship between the target scanning area and the target features, as well as the target scanning area.

S140. Scan the object to be scanned based on the position of the start scan line and the position of the end scan line.

Exemplarily, according to the position parameter of the starting scan line and the position parameter of the ending scan line, it is imported into the 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 parameters of the start scan line and the position parameters of the end scan line are imported into the scanning protocol of the object to be scanned. After the start scan line and end scan line are drawn in the body area map, you can click the "OK" button in Figure 2 to import the position parameters of the start scan line and the end scan line into the object to be scanned in the scanning protocol. This enables precise scanning of the object to be scanned based on a precisely determined scanning range.

Optionally, the scanning of the object to be scanned based on the position of the start scan line and the position of the end scan line may specifically be: comparing the position parameter of the start scan line and the position parameter of the end scan line. The position parameter is added to the scanning protocol of the object to be scanned; the object to be scanned is scanned based on the scanning protocol.

Exemplarily, the determined position parameters of the starting scan line and the position parameters of the ending scan line may be added to the scanning protocol of the object to be scanned, and the object to be scanned is scanned based on the scanning protocol.

Optionally, the scanning of the object to be scanned based on the scanning protocol may be: performing an initial scan of the object to be scanned, and determining the characteristics of the object to be scanned and the bed code value of the scanning bed based on the initial scanning result. The corresponding relationship; based on the position of the starting scan line and the position of the ending scan line in the scanning protocol, the corresponding relationship between each feature of the object to be scanned and the bed code value of the scanning bed, determine the starting point of the object to be scanned. The actual position of the scan line and the actual position of the end scan line; the object to be scanned is scanned based on the actual position of the start scan line and the actual position of the end scan line.

Exemplarily, after the object to be scanned is lying on the scanning bed, the object to be scanned is initially scanned to obtain an initial scanned image of the object to be scanned, and the corresponding relationship between each feature of the object to be scanned and the bed code value of the scanning bed is determined, Specifically, the corresponding relationship between each feature and the bed code value of the scanning bed may be determined according to the pixel value of each pixel point in the initial scanned image. In the initial scanned image, the pixel value of each pixel can represent a bed code value, so that the corresponding relationship between each feature and the bed code value of the scanning bed can be obtained by using the initial scanned image, and the starting point of the object to be scanned can be determined. The actual position of the scan line and the actual position of the end scan line.

Based on the position of the start scan line and the position of the end scan line in the scanning protocol, and the correspondence between each feature of the object to be scanned and the bed code value of the scan bed, the actual position of the start scan line for scanning the object to be scanned can be determined and the actual position of the end scan line, that is, the bed code value of the start scan line and the bed code value of the end scan line where the object to be scanned is scanned. Based on the bed code value of the starting scan line and the bed code value of the ending scan line, the scanning range of the object to be scanned can be determined, and the object to be scanned can be scanned with a purpose based on the scanning range. In this way, the scanning range of the object to be scanned can be accurately determined based on each feature, the problem of artificially adjusting the scanning range in the prior art is solved, and the effect of efficiently and accurately determining the scanning range is achieved.

The technical solution of the embodiment of the present invention is to obtain the target scanning area and the human body area map of the object to be scanned, and determine the target feature corresponding to the target scanning area based on the target scanning area and the human body area map, so that the target scanning area can be scanned. The area is transferred to the target feature, so that the scanning range of the object to be scanned can be subsequently determined based on the target feature. Based on the target feature and the target scan area, the position of the start scan line and the position of the end scan line for scanning the object to be scanned are determined, so as to be determined based on the position of the start scan line and the position of the end scan line The scanning range of the object to be scanned solves the problem in the prior art that the starting scanning bed code value and the ending scanning bed code value of the scanning range need to be manually determined. By using the body area map and the target scanning area, the to-be-scanned area can be automatically determined The scanning range of the object realizes the effect of efficiently and accurately determining the scanning range. Based on the position of the starting scan line and the position of the ending scan line, the object to be scanned is scanned, so that the object to be scanned can be accurately scanned based on the accurately determined scanning range.
