[0047] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of the present invention.

[0048] In the embodiments of the present application, the word "exemplary" is used to mean "used as an example, illustration or description". Any embodiment described as "exemplary" in the embodiments of the present application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is given to enable any technician in the field to implement and use the present invention. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present invention can be implemented without using these specific details. In other examples, well-known structures and processes will not be elaborated in detail to avoid unnecessary details that make the description of the present invention obscure. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest range of principles and features disclosed in the embodiments of the present application.

[0049] In order to facilitate understanding of the contrast scanning control method, device, equipment and readable storage medium provided in the embodiments of the present application, the application scenario of the contrast scanning control method is first described accordingly. Specifically, the contrast scanning control method provided in the embodiments of the present application is generally applied to CT angiography or other implementation scenarios in which contrast agents are used as an auxiliary, and the human body is scanned and imaged through CT, nuclear magnetic resonance and other technologies to obtain medical images so as to identify and diagnose lesions. Normally, a contrast agent can be injected intravenously into the target imaging area, and then the target imaging area is scanned using a scanning device when the contrast agent flows through the vein to obtain a venous contrast image.

[0050] Generally speaking, the dose of contrast agent usually affects the imaging effect of contrast images, that is, the higher the dose of contrast agent, the better the imaging effect of the contrast image obtained by scanning. However, based on the needs of actual scenarios, how to better obtain contrast images with high imaging effect at a low contrast dose has also become the key to current contrast technology.

[0051] Precisely to solve the above-mentioned problems, the present application provides a contrast scanning control method, device, equipment and readable storage medium, which analyzes the initial contrast image and adjusts the scanning parameters, thereby ensuring that medical images with good imaging effects can be obtained even with low doses of contrast agents. Specifically, the contrast scanning control method is usually set in a contrast scanning control device in the form of a computer program, and the contrast scanning control device is usually set in a computer device in the form of a processor, such as a control device of a scanning terminal device (such as a CT scanner, a nuclear magnetic resonance apparatus). The contrast scanning control device in the computer device executes the contrast scanning control method provided in the embodiment of the present application by running the computer program corresponding to the contrast scanning control method. For details, please refer to Figure 1 , Figure 1 A schematic flow chart of a method for controlling angiography scanning provided in an embodiment of the present application, specifically, comprising steps S110 to S130:

[0052] S110, in response to an operation instruction to inject a contrast agent into a target area of ​​a target user, the target area is scanned by a preset scanning terminal with preset initial scanning parameters to obtain an initial contrast image corresponding to the target area.

[0053] In the embodiment of the present application, the target user can be understood as a user who needs to undergo medical scanning and imaging, for example, the target user can be a patient in general, and the target area can be understood as a physiological tissue area where the user needs to undergo medical scanning and imaging to assist in diagnosis, for example, the more common target area can be the bile duct, urinary system, blood vessels, etc. In addition, considering the relevant technology and the realization of the automation of injection, therefore, after the injection instruction of the target area is realized through the automation system, that is, the medical staff inputs the operation instruction of injecting the contrast agent through the automation system to inject the contrast agent of the specified dose, injection time and injection speed into the target area of ​​the target user, the contrast scanning control device will scan the target area with the preset initial scanning parameters, such as the scanning position and scanning speed, etc., by controlling the preset scanning terminal, such as the CT scanner and the nuclear magnetic resonance instrument mentioned above, so as to obtain the initial contrast image in the target area.

[0054] Specifically, considering that the imaging technology usually requires imaging of a specific physiological tissue in the target area, in order to obtain the imaging image of a specific target physiological tissue in the target area, in the embodiment of the present application, the above content will be implemented based on the target tracking technology. For example, as a feasible embodiment of the present application, please refer to Figure 2 , Figure 2A schematic flow chart of a step of obtaining a specific physiological tissue angiography image based on target tracking provided in an embodiment of the present application, specifically, comprising steps S210 to S230:

[0055] S210, scanning and acquiring an initial angiography image corresponding to the target area by using a preset scanning terminal and preset initial scanning parameters.

[0056] In the embodiment of the present application, in the aforementioned process of acquiring contrast images, the contrast scanning control device will first control the scanning terminal to scan the target area at a specific scanning angle and when the contrast agent flows through the veins in the target area, so as to obtain an initial contrast image containing the specified target physiological tissue in the area.

[0057] Specifically, considering that different scanning terminals have different scanning performances, in order to better control the scanning terminal to scan the target area when the contrast agent flows through the veins in the target area, as another feasible embodiment of the present application, the scanning start time is determined according to the terminal type of the scanning terminal and the initial time corresponding to the injection of the contrast agent, and the scanning of the target area is completed at the scanning start time to ensure that the target area is scanned when the contrast agent flows through the veins in the target area. For details, please refer to Figure 3 , Figure 3 The schematic flow chart of the steps for obtaining angiographic images at a specific scanning time provided in the embodiment of the present application specifically includes steps S310 to S330:

[0058] S310: Obtain a preset terminal type of a scanning terminal.

[0059] In the embodiment of the present application, the terminal type of the scanning terminal may be a CT scanner, a nuclear magnetic resonance imaging device, etc. Of course, it may also be further divided into terminal models of the scanning terminal.

[0060] S320: Determine a scanning start time according to a scanning interval corresponding to the terminal type and an initial time corresponding to the injection of the contrast agent.

[0061] In the embodiment of the present application, after the terminal type of the scanning terminal is determined as mentioned above, the scanning start time of the contrast agent flowing through the vein is further determined based on the scanning interval corresponding to the terminal type, which is usually 1 to 2 seconds, and the initial time corresponding to the injection of the contrast agent.

[0062] S330, in response to the scanning start time, scanning by the scanning terminal with preset initial scanning parameters to obtain an initial angiography image corresponding to the target area.

[0063] In the embodiment of the present application, at the start time of the scan, since the contrast agent flows through the vein, an initial contrast image with relatively better quality can be obtained by controlling the scanning terminal to scan the target area at a specific scanning angle.

[0064] Through the above-mentioned method, it can be effectively ensured that the target area is scanned when the contrast agent flows through the veins in the target area, thereby further improving the subsequent analysis effect of the contrast image and ensuring the quality of the contrast image obtained subsequently.

[0065] S220: Determine a target tissue from the initial contrast image according to the initial contrast image and a reference contrast image corresponding to the initial contrast image.

[0066] In the embodiment of the present application, based on the aforementioned initial contrast image containing the specified target physiological tissue in the area, by comparing the initial contrast image with a pre-set reference contrast image, the target tissue that needs to be contrasted for auxiliary diagnosis, i.e., the specific physiological tissue mentioned above, can be determined from the initial contrast image.

[0067] S230, performing tracking scanning on the target tissue through a preset scanning terminal to obtain an initial angiography image corresponding to the target area.

[0068] In the embodiment of the present application, after the target tissue in the initial contrast image is identified, the contrast scanning control device will further control the scanning terminal to track the target tissue at a corresponding scanning speed and continue scanning, thereby obtaining a contrast image containing the target tissue. The contrast image can be understood as the initial contrast image corresponding to the target area.

[0069] In addition, it should be noted that in response to the operation instruction of injecting contrast agent into the target area of ​​the target user, it is necessary to control the process of injecting the contrast agent of a specified dose, injection time and injection speed into the target area of ​​the target user, wherein the parameters of the contrast agent can also be realized by analyzing the physiological characteristics of the target user. For details, please refer to Figure 4 , Figure 4 A schematic flow chart of a step of determining injection parameters based on physiological characteristics to inject a contrast agent is provided in an embodiment of the present application, specifically, including steps S410 to S430:

[0070] S410, obtaining physiological characteristics of the target user.

[0071] In the embodiment of the present application, the physiological characteristics may generally include at least one of the user's body surface characteristics, physiological tissue characteristics, and blood vessel density, etc.

[0072] S420, determining the injection dose and injection rate of the contrast agent according to the physiological characteristics.

[0073] In the embodiment of the present application, in the aforementioned process, the user's health status can be determined by analyzing physiological characteristics, such as analyzing body surface characteristics and physiological tissue characteristics, or the injection dose and injection rate suitable for contrast agent injection can be determined based on the user's blood vessel density and a preset mapping curve. Under normal circumstances, the injection dose in the embodiment of the present application can be set relatively lower.

[0074] S430, injecting contrast agent into the target area at the injection dose and the injection rate.

[0075] In an embodiment of the present application, on the basis of the foregoing, while injecting contrast agent into the target area by specifying the injection dose and injection speed, the initial injection time of the contrast agent will be recorded. The initial injection time will affect the subsequent time of flowing through the veins in the target area, thereby being used to better scan the target area to obtain a relatively high-quality initial contrast image.

[0076] In the embodiment of the present application, by completing the injection of contrast agent with specified injection parameters based on physiological characteristics, the effect of subsequent scanning and imaging of the target area can be further improved.

[0077] S120, adjusting the initial scanning parameters according to the image quality parameters of each image frame in the initial contrast image to obtain target scanning parameters.

[0078] After the initial contrast image in the target area is acquired through the initial scanning parameters as mentioned above, considering that under normal circumstances, a low contrast dose will affect the effect of the contrast image, therefore, in order to improve the effect of the contrast images acquired subsequently, in an embodiment of the present application, the image quality of each image frame in the initial contrast image is further analyzed accordingly to appropriately adjust and optimize the scanning parameters, such as the scanning position and the scanning speed, so as to obtain scanning parameters that can subsequently achieve better scanning effects.

[0079] For more information, please refer to Figure 5 , Figure 5 A schematic flow chart of a step of adjusting initial scanning parameters based on image quality parameters provided in an embodiment of the present application, specifically, comprising steps S510 to S520:

[0080] S510: Determine a brightness difference between adjacent image frames in the initial contrast image according to brightness information of each image frame in the initial contrast image.

[0081] In the embodiment of the present application, the brightness information of the image frame is used as the image quality parameter to adjust the scanning parameters. Specifically, the brightness information of the image frame can be obtained based on the statistics of the pixel values ​​of each pixel in the image frame, for example, it can be the average brightness value of each pixel in the image frame. Of course, in a specific application scenario, it can also be the average brightness of a part of the image frame, such as the recognized physiological tissue, etc.

[0082] On this basis, combined with the brightness difference between adjacent image frames in the initial contrast image, the quality of the contrast image can be judged as a whole, that is, the quality of the contrast image obtained under the scanning parameters can be determined.

[0083] S520: Adjust the initial scanning parameters according to the brightness difference and a preset difference threshold to obtain target scanning parameters.

[0084] In the embodiment of the present application, based on the aforementioned determination of the brightness difference between adjacent image frames in the initial contrast image, the scanning parameters can be adjusted by comparing the brightness difference with a preset difference threshold. For details, please refer to Figure 6 , Figure 6 Taking the scanning speed as an example, a schematic flow chart of the steps of adjusting the initial scanning parameters based on the brightness difference is provided, specifically, including steps S610 to S620:

[0085] S610: If the brightness difference is greater than a preset difference threshold, the scanning speed in the initial scanning parameters is reduced to obtain target scanning parameters.

[0086] In an embodiment of the present application, when the brightness difference is greater than the difference threshold, it indicates that the image quality is poor due to the fast scanning speed during the scanning process. Therefore, the scanning speed in the scanning parameters can be appropriately reduced to obtain the adjusted target scanning parameters, thereby facilitating the subsequent scanning process to avoid poor image quality due to the fast change in scanning speed, thereby improving the quality of the obtained image.

[0087] S620: If the brightness difference is less than a preset difference threshold, increase the scanning speed in the initial scanning parameters to obtain target scanning parameters.

[0088] In the embodiment of the present application, similarly, when the brightness difference is less than the preset difference threshold, it indicates that there is a possibility that the target area cannot be fully scanned due to the low scanning speed during the scanning process. Therefore, the scanning speed in the scanning parameters can be appropriately increased to ensure the subsequent scanning effect of the image.

[0089] In addition, in the process of determining the brightness difference value by using the brightness information to determine the image quality, the tissue characteristics of the target tissue in the image can be further analyzed. For details, please refer to Figure 7 ,like Figure 7 As shown, Figure 7 A schematic flow chart of a step of determining a brightness difference based on tissue features to adjust scanning parameters provided in an embodiment of the present application, specifically, comprising steps S710 to S720:

[0090] S710, performing target recognition on the initial contrast image to obtain tissue features of target physiological tissue in the initial contrast image.

[0091] In the embodiment of the present application, the tissue characteristics include at least one of tissue density and tissue area.

[0092] S720: If the tissue feature meets the preset feature requirement, determine the brightness difference between adjacent image frames in the initial contrast image according to the brightness information of each image frame in the initial contrast image.

[0093] In an embodiment of the present application, when tissue features meet preset feature requirements, such as tissue density is higher than a preset density threshold, or tissue area is higher than a preset area threshold, it indicates that there is relatively obvious physiological tissue in the image, and therefore it is more necessary to perform scanning control on the image. Therefore, the brightness difference between adjacent image frames in the initial contrast image can be determined based on the brightness information of each image frame in the initial contrast image. Conversely, when there is no relatively obvious physiological tissue in the image, the operation of scanning control on the image can be reduced.

[0094] In order to better implement the contrast scanning control method in the embodiment of the present application, based on the contrast scanning control method, a contrast scanning control device is also provided in the embodiment of the present application.

[0099] In some embodiments of the present application, the adjustment module 820 is used to reduce the scanning speed in the initial scanning parameters to obtain the target scanning parameters if the brightness difference is greater than a preset difference threshold; and / or, if the brightness difference is less than a preset difference threshold, increase the scanning speed in the initial scanning parameters to obtain the target scanning parameters.

[0101] In some embodiments of the present application, the response module 810 is also used to obtain an initial contrast image corresponding to the target area by scanning with preset initial scanning parameters through a preset scanning terminal; determine the target tissue from the initial contrast image based on the initial contrast image and a reference contrast image corresponding to the initial contrast image; and track and scan the target tissue through a preset scanning terminal to obtain the initial contrast image corresponding to the target area.

[0102] In some embodiments of the present application, the response module 810 is also used to obtain a terminal type of a preset scanning terminal; determine a scanning start time according to a scanning interval corresponding to the terminal type and an initial time corresponding to the injection of the contrast agent; in response to the scanning start time, scan the scanning terminal with preset initial scanning parameters to obtain an initial contrast image corresponding to the target area.

[0103] In some embodiments of the present application, before the response module 810 is used to scan the target area with preset initial scanning parameters through a preset scanning terminal to obtain an initial imaging image corresponding to the target area, the response module 810 is also used to obtain physiological characteristics of the target user; the physiological characteristics include at least one of body surface characteristics, physiological tissue characteristics and blood vessel density; determine the injection dose and injection rate of the contrast agent according to the physiological characteristics; and inject the contrast agent into the target area at the injection dose and the injection rate.
