[0002] Currently, doctors frequently use ultrasound medical equipment to examine arterial blood flow in various tissues of patients. For example, ultrasound examination of the renal artery is used to detect renal artery stenosis with significant hemodynamic changes; renal color Doppler ultrasound is mainly used for spectral-related measurements of renal artery blood flow and other parameters. The locations for renal artery measurements mainly include the initial segment, middle segment, distal segment, and intrarenal segment. Routine measurements of the intrarenal segment include the renal segmental arteries and interlobar arteries. Due to the large number of measurements and the fact that renal blood flow is easily affected by factors such as the patient's breathing, the current method of manually examining each segment individually places high demands on the operator, resulting in low examination efficiency and difficulty in operation.

[0064] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0065] Please refer to Figure 1 , Figure 1 A flowchart illustrating an ultrasound examination method for arterial blood flow provided in an embodiment of the present invention. The method may include:

[0066] Step 101: Acquire blood flow scanning section images from ultrasound equipment.

[0067] It is understood that the blood flow scanning cross-sectional image in this step can be a cross-sectional image (i.e., ultrasound image) acquired by the ultrasound equipment when performing a blood flow scan; that is, a cross-sectional image acquired by the ultrasound equipment when the operator (such as a doctor) uses the ultrasound equipment to perform a blood flow scan.

[0068] Correspondingly, the specific process of acquiring the blood flow scanning section image collected by the ultrasound device in this step can be set by the designer according to the practical scenario and user needs. For example, the processor can control the ultrasound device to acquire the blood flow scanning section image according to the acquired general blood flow scanning command. The general blood flow scanning command can be used to scan and identify the corresponding section areas of all preset section types in the blood flow scanning section image, so as to determine the corresponding ultrasound placement point according to the arterial blood flow area in these section areas. For example, the operator can operate the ultrasound device to trigger the general blood flow scanning command and operate the ultrasound probe of the ultrasound device to perform blood flow scanning on the human body parts (such as the neck, kidneys, or heart) that need to be examined by ultrasound. The processor can also control the ultrasound device to acquire blood flow scanning section images according to the blood flow scanning commands of different scanning types. Each blood flow scanning command of a specific scanning type can be used to scan and identify the corresponding preset section regions in the blood flow scanning section image. This configuration of scanning types reduces the computational load for section region identification and improves the accuracy of section region identification. For example, the operator can trigger the corresponding blood flow scanning command based on the body part requiring ultrasound examination of arterial blood flow (such as the neck, kidneys, or heart), and operate the ultrasound probe of the ultrasound device to perform blood flow scanning on that body part, identifying the specific section region. By configuring the scanning type, the operator can identify the preset section regions corresponding to that scanning type in the image, avoiding interference from irrelevant preset section regions and improving the accuracy of section region identification. This embodiment does not impose any limitations on this.

[0069] It is understood that the blood flow scanning cross-sectional images in this step can also be obtained from a storage medium used to store ultrasound video / images. In one embodiment, cross-sectional images of blood flow scanning of a human body part can be acquired using an ultrasound device and stored in a storage medium. When performing step 101, the pre-stored blood flow scanning cross-sectional images can be retrieved from the storage medium.

[0070] Step 102: Identify the arterial blood flow region in each section region of the blood flow scanning section image; wherein, the section type of each section region is any preset section type.

[0071] It should be noted that in this embodiment, the processor can detect and identify the arterial blood flow regions in each section region (i.e., tissue region) of the blood flow scanning section image. This means identifying the regions where blood flow is located in the arteries within each section region, thereby determining the location and extent of each section region and the arterial blood flow regions within them. In this embodiment, each section region identified in the blood flow scanning section image can correspond to a preset section type. That is, the processor can identify one or more section regions corresponding to each preset section type from the blood flow scanning section image. The preset section type can be a pre-defined section type (i.e., tissue location) that needs to be examined by arterial blood flow ultrasound. This is the section type used to identify the corresponding area. For example, the kidney includes tissue locations such as the distal renal artery, renal segmental artery, and interlobar artery. Therefore, when the preset section type includes the distal renal artery, renal segmental artery, and interlobar artery, the processor can identify the section areas of the distal renal artery, renal segmental artery, and interlobar artery in the blood flow scanning section image in this step, so as to further identify the arterial blood flow area in each section area.

[0072] Correspondingly, the specific number and type of preset slice types in this embodiment, i.e., the number and type of slice areas that blood flow scanning can identify, can be set by the designer according to the usage scenario and user needs. For example, the preset slice types may include slice types for kidney scanning, and the slice types for kidney scanning may include types such as the distal renal artery and / or intrarenal segmental arteries (such as renal segmental arteries and / or interlobar arteries). Therefore, the preset slice types may include the distal renal artery and / or renal segmental arteries and / or interlobar arteries, so that the processor can scan the patient's kidneys using ultrasound equipment. When positioned, the system identifies the sectional regions of the distal renal artery and / or renal segmental arteries and / or interlobar arteries in the blood flow scanning image, thereby enabling ultrasound examination of renal arterial blood flow. The preset section type can also be a neck scan section type, such as the carotid artery and / or vertebral artery. The preset section type can also include section types of other tissue sites in the human body to enable ultrasound examination of arterial blood flow in other tissue sites. For example, the preset section type can also include a cardiac scan section type, which may include apical four-chamber and / or apical five-chamber views. This embodiment does not impose any limitations in this regard.

[0073] The specific process for identifying the arterial blood flow region in each section of the blood flow scanning image in this step can be set by the designer according to the practical scenario and user needs. For example, the processor can identify the section region in the blood flow scanning image based on the grayscale image corresponding to the blood flow scanning image; identify the arterial blood flow region in the blood flow scanning image based on the color image (such as a three-channel RGB image) corresponding to the blood flow scanning image; and determine the arterial blood flow region in each section of the blood flow scanning image based on the section region and the arterial blood flow region in the blood flow scanning image. The processor can also first identify the slice regions in the blood flow scanning slice image based on the grayscale image corresponding to the slice region in the blood flow scanning slice image; then, based on the color image corresponding to the slice region in the blood flow scanning slice image, it can identify the arterial blood flow region in each slice region. In other words, the processor can use the color image content corresponding to each slice region in the identified blood flow scanning slice image to identify the arterial blood flow region in each slice region. For example, the processor uses an image segmentation algorithm to perform blood flow segmentation on the color image corresponding to the slice region in the blood flow scanning slice image, identifying the arterial and venous blood flow regions in each slice region of the blood flow scanning slice image. This embodiment does not impose any limitations on this.

[0074] Correspondingly, in this step, the processor can identify the arterial blood flow region in each section region of the blood flow scanning image according to the scanning type of the acquired blood flow scanning command; wherein, the scanning type corresponds to the preset section type, that is, the section type of each section region in the identified blood flow scanning image can be the preset section type corresponding to the scanning type in the blood flow scanning command; the scanning type can include kidney blood flow scanning and / or neck blood flow scanning and / or cardiac blood flow scanning, etc. In other words, the processor can identify the cut regions corresponding to each preset cut type from the blood flow scan cross-section image based on the scan type of the acquired blood flow scan command. By setting the scan type of the blood flow scan command, the computational load of cut region identification can be reduced. For example, all scan types can include kidney blood flow scan corresponding to the kidney scan cut type, neck blood flow scan corresponding to the neck scan cut type, and heart blood flow scan corresponding to the heart scan cut type. When the blood flow scan command's scan type is kidney blood flow scan, the preset cut type corresponding to kidney blood flow scan can be... The processor can identify these areas from the blood flow scan images, including the distal renal artery, segmental renal arteries, and interlobar arteries. This allows it to pinpoint the arterial blood flow regions within these areas. When the blood flow scan command specifies a neck blood flow scan, the preset scan type for the kidney blood flow scan can include the carotid artery and / or vertebral artery in the neck. When the blood flow scan command specifies a cardiac blood flow scan, the preset scan type for the cardiac blood flow scan can include the apical four-chamber and / or apical five-chamber heart in the neck. Accordingly, in step 101, the processor can control the ultrasound equipment to acquire blood flow scan images based on the different scan types of blood flow scan commands acquired.

[0075] For example, in some embodiments, the processor can identify the section region in the blood flow scanning section image using the grayscale image corresponding to the blood flow scanning section image, based on the scanning type of the acquired blood flow scanning command; identify the arterial blood flow region in the blood flow scanning section image using the color image corresponding to the blood flow scanning section image; and determine the arterial blood flow region in each section region of the blood flow scanning section image based on the section region and the arterial blood flow region in the blood flow scanning section image.

[0076] Furthermore, after step 102, the processor can display markings on the blood flow scanning section image; wherein, the markings include the marking information corresponding to the section area and / or arterial blood flow area in the blood flow scanning section image and / or the arterial blood flow area in each section area; thereby, by displaying the markings on the blood flow scanning section image, the operator can easily view the specific situation of the blood flow scanning section image, so as to facilitate the environmental viewing and configuration selection of the ultrasound placement point that needs to be performed in the subsequent ultrasound examination.

[0077] Step 103: Based on the arterial blood flow region, determine the corresponding ultrasound placement point for each section region, so as to perform ultrasound examination at the ultrasound placement point; wherein, the ultrasound placement point is within the arterial blood flow region.

[0078] It is understood that the ultrasound placement point in this embodiment can be a point within the slice area where blood flow ultrasound examination can be performed, such as the point where the PW (pulse Doppler) frame is placed; the number of ultrasound placement points in each slice area in the blood flow scanning slice image can be no more than 1, that is, the ultrasound placement point can be the optimal point within the slice area where blood flow ultrasound examination can be performed, such as the location of the artery with the most abundant blood flow.

[0079] Correspondingly, the specific method for determining the corresponding ultrasound placement point for each slice region based on the arterial blood flow region in this step can be set by the designer according to the usage scenario and user needs. For example, when the number of ultrasound placement points in each slice region of the blood flow scan image is no more than 1, the processor can determine a target region in each slice region based on the arterial blood flow region in each slice region of the blood flow scan image; where the target region is any arterial blood flow region; and determine the corresponding ultrasound placement point for each slice region based on the target region; where the ultrasound placement point is within the target region. When the number of ultrasound placement points in each slice region is not limited, the processor can determine one ultrasound placement point (such as the center point) from each arterial blood flow region in each slice region of the blood flow scan image, so that the operator can subsequently select the arterial blood flow region in each slice region for blood flow ultrasound examination at the corresponding ultrasound placement point.

[0080] Correspondingly, the method provided in this embodiment, after determining the ultrasound placement points corresponding to each slice region, can also perform ultrasound examination on all or some of the ultrasound placement points to obtain and display the arterial blood flow spectrum corresponding to the ultrasound placement points, thus completing the ultrasound examination of arterial blood flow in the corresponding slice region. For example, the processor can directly perform ultrasound examination on all ultrasound placement points to obtain and display the arterial blood flow spectrum of each slice region; wherein, the number of ultrasound placement points in each slice region in the blood flow scanning slice image is no greater than 1.

[0081] Correspondingly, the processor can also perform ultrasound examination at the target placement point in the ultrasound placement point according to the acquired selection section ultrasound command, and obtain and display the arterial blood flow spectrum of the section region corresponding to the selection section ultrasound command; wherein, the number of ultrasound placement points in each section region in the blood flow scanning section image is no more than 1, and the target placement point is the ultrasound placement point in the section region corresponding to the selection section ultrasound command; that is, the operator can select one or more section regions in the blood flow scanning section image to trigger the selection section ultrasound command, so that the processor can perform ultrasound examination at the ultrasound placement point in the section region selected by the user and obtain the arterial blood flow spectrum of these section regions.

[0082] In other embodiments, when the number of ultrasound placement points in each section region is not limited, the processor can also perform ultrasound examination on the ultrasound placement points corresponding to the selected ultrasound placement command according to the acquired selected ultrasound placement command, and obtain and display the arterial blood flow spectrum of the ultrasound placement points corresponding to the selected ultrasound placement command; that is, the operator can select one or more ultrasound placement points in each section region of the blood flow scanning section image to trigger the selected ultrasound placement command, so that the processor can perform ultrasound examination on the ultrasound placement points selected by the user and obtain the arterial blood flow spectrum of these ultrasound placement points.

[0083] In this embodiment, the present invention identifies the arterial blood flow regions in each section of the blood flow scanning section image, thereby simultaneously identifying and capturing all arterial blood flow in each tissue part of the image; by determining the corresponding ultrasound placement point for each section region based on the arterial blood flow region, the ultrasound examination position of arterial blood flow in each tissue part can be automatically determined, thereby realizing the ultrasound examination of the captured arterial blood flow, reducing the operational difficulty of ultrasound examination of arterial blood flow, and improving the examination efficiency.

[0084] Please refer to Figure 2 , Figure 2 A flowchart illustrating another method for ultrasound examination of arterial blood flow provided in an embodiment of the present invention. The method may include:

[0085] Step 201: Acquire blood flow scanning section images from ultrasound equipment.

[0086] This step is similar to step 101, and will not be described again here.

[0087] Step 202: Identify the slice regions in the blood flow scanning slice image based on the grayscale image corresponding to the blood flow scanning slice image; wherein, the slice type of each slice region is any preset slice type.

[0088] It is understood that in this embodiment, the blood flow scanning section images acquired by the ultrasound equipment can be analyzed in two dimensions: grayscale image and color image, in order to determine the arterial blood flow region in each section region of the blood flow scanning section image.

[0089] Correspondingly, in this step, the processor can analyze the grayscale image without blood flow to identify the cut surfaces and positions of each preset cut surface type in the blood flow scanning section image, thereby obtaining the section regions in the blood flow scanning section image. The specific method by which the processor identifies the section regions in the blood flow scanning section image based on the corresponding grayscale image can be set by the designer. For example, the processor can use an object detection algorithm to detect the corresponding grayscale image and identify the section regions; for instance, the processor can use the YOLO (You Only Look Once) object detection algorithm to detect the cut surfaces and positions in the corresponding grayscale image in real time, thereby obtaining the section regions in the blood flow scanning section image. The processor can also use other object detection algorithms or other methods to detect the corresponding grayscale image and identify the section regions in the blood flow scanning section image. This embodiment does not impose any limitations on this.

[0090] Correspondingly, in this step, the processor can identify the slice region in the blood flow scanning slice image based on the scanning type of the acquired blood flow scanning command and the grayscale image corresponding to the blood flow scanning slice image. The slice type of each slice region is any preset slice type corresponding to the scanning type. For example, the scanning type of the blood flow scanning command can be renal blood flow scanning, neck blood flow scanning, or cardiac blood flow scanning. The preset slice type corresponding to renal blood flow scanning can specifically include distal renal artery, renal segmental artery, and interlobar artery, etc. In other words, this embodiment can perform arterial blood flow scanning. When ultrasound examinations cover numerous body parts (such as the neck, kidneys, and heart), resulting in a large number of corresponding tissue areas (i.e., preset section types), this embodiment utilizes scan type settings to differentiate blood flow scan commands in order to facilitate section area identification and reduce computational load. The operator can trigger the corresponding blood flow scan command based on the actual needs of the scan location. The processor can then identify the corresponding preset section area from the blood flow scan section image based on the scan type of the acquired blood flow scan command. Accordingly, in step 201, the processor can control the ultrasound equipment to acquire blood flow scan section images based on the acquired blood flow scan commands of different types.

[0091] Step 203: Identify the arterial blood flow region in the blood flow scanning section image based on the color image corresponding to the blood flow scanning section image.

[0092] In this step, the processor can analyze the color image containing blood flow to identify the location of arterial blood flow in the blood flow scanning section image, thus obtaining the arterial blood flow region in the blood flow scanning section image. The specific method by which the processor identifies the arterial blood flow region in the blood flow scanning section image based on the color image corresponding to the blood flow scanning section image can be set by the designer. For example, the processor can use image segmentation algorithms to segment the blood flow in the color image corresponding to the blood flow scanning section image to identify the arterial blood flow region in the blood flow scanning section image; for example, the processor can use YOLO-SEG (a target segmentation algorithm) to segment the blood flow in the RGB image (red, green, and blue three-channel image) corresponding to the blood flow scanning section image to identify the arterial blood flow region in the blood flow scanning section image, i.e., each connected region (mask) of the arterial blood flow; or, all connected regions of the arterial blood flow can be used as separate arterial blood flow regions, or only connected regions of arterial blood flow with an area greater than a threshold can be used as arterial blood flow regions. The processor can also utilize other image segmentation algorithms or other methods to segment the blood flow in the color image corresponding to the blood flow scanning section image and identify the arterial blood flow region in the blood flow scanning section image. This embodiment does not impose any limitations on this.

[0093] Accordingly, in this step, the processor can also identify the arterial and venous blood flow regions in the blood flow scanning section image based on the color image corresponding to the blood flow scanning section image. This facilitates the subsequent display of the dynamic and static distinction between arterial and venous blood flow, making it easier for the operator to view. For example, the processor can use an image segmentation algorithm (such as YOLO-SEG) to perform blood flow segmentation on the RGB image corresponding to the blood flow scanning section image, identifying the arterial and venous blood flow regions in the blood flow scanning section image.

[0094] It should be noted that this embodiment does not limit the logical order of steps 202 and 203. Step 202 can be performed first and then step 203, as shown in this embodiment; or step 203 can be performed first and then step 202, or both steps can be performed simultaneously. As long as the blood flow scanning section image can be analyzed in both grayscale and color dimensions to determine the arterial blood flow region in each section region of the blood flow scanning section image, this embodiment does not impose any restrictions on this.

[0095] Step 204: Based on the cross-sectional area and arterial blood flow area in the blood flow scanning cross-sectional image, determine the arterial blood flow area in each cross-sectional area of ​​the blood flow scanning cross-sectional image.

[0096] Understandably, in this step, the processor can determine the arterial blood flow region in each section region based on the section region and arterial blood flow region in the identified blood flow scanning section image.

[0097] Accordingly, in this embodiment, the processor can also display labeling content on the blood flow scanning section image; wherein, the labeling content includes the labeling information corresponding to the section region and / or arterial blood flow region and / or venous blood flow region and / or the arterial blood flow region in each section region in the blood flow scanning section image. The labeling information corresponding to the section region in the blood flow scanning section image consists of the label box and text label corresponding to each section region. Taking the kidney as an example, the scanning site is... Figure 3 The image displays text labels and rectangles for cross-sectional areas of the interlobar arteries, segmental arteries (i.e., renal segmental arteries), and distal renal arteries of the kidney; the labeling information corresponding to the arterial blood flow areas in the blood flow scan cross-sectional image is a first preset color (e.g., ...). Figure 3 The red staining markers in the blood flow scan section image are used to identify the venous blood flow regions, and the corresponding marker information is a second preset color (e.g., red). Figure 3 The blue staining in the image distinguishes arterial (red) and venous (blue) blood flow by the difference in staining color. The arterial blood flow regions in each section of the blood flow scan image are identified by edge lines and text labels, such as... Figure 3 The edges of the arterial blood flow regions in the different cross-sectional regions a1, a2, b1, b2, b3, c1, c2, and c3 are connected by lines and text labels.

[0098] Step 205: Based on the arterial blood flow regions in each section region of the blood flow scanning section image, determine a target region in each section region; wherein, the target region is any arterial blood flow region.

[0099] Understandably, in this step, the processor can select one arterial blood flow region from each arterial blood flow region within each slice region as the target region for each slice region. The specific method for determining a target region within each slice region based on the arterial blood flow regions in the blood flow scanning slice image can be set by the designer. For example, the processor can determine the largest arterial blood flow region in the current slice region as the target region, i.e., the largest arterial blood flow region is considered the region with the most abundant blood flow; where the current slice region can be any slice region; for example... Figure 3 As shown, the processor can identify the arterial blood flow region with the largest area (i.e., the largest connected region mask) from the two arterial blood flow regions a1 and a2 as the target region in the cross-sectional region of the interlobar artery. Alternatively, the processor can determine the arterial blood flow region with the largest vessel diameter in the current cross-sectional region as the target region, that is, the arterial blood flow region with the largest vessel diameter is considered the region with the most abundant blood flow. This embodiment does not impose any limitations on the processor's ability to determine a target region from each cross-sectional region, provided that the processor can do so.

[0100] In this embodiment, the processor determines a target region in each section based on the arterial blood flow region in each section of the blood flow scanning section image in step 205. In other embodiments, the processor can also determine one or more target regions in each section based on the arterial blood flow region in each section of the blood flow scanning section image. For example, the processor can also determine the arterial blood flow region with the largest blood vessel diameter and the arterial blood flow region with the largest area in the current section as the target regions in the current section. This embodiment does not impose any restrictions on this.

[0101] Step 206: Determine the corresponding ultrasound placement points for each section region based on the target region; wherein, the ultrasound placement points are located within the target region.

[0102] Understandably, in this step, the processor can select one or more points in each target area as ultrasound placement points to perform ultrasound examinations at those points. For example, the processor can select one point in each target area as an ultrasound placement point, meaning the number of ultrasound placement points for each section area can be one.

[0103] Correspondingly, the specific method by which the processor determines the corresponding ultrasound placement point for each cross-sectional area based on the target area in this embodiment can be set by the designer according to the practical scenario and user needs. For example, the processor can determine the center point of each target area as the corresponding ultrasound placement point for each cross-sectional area; the processor can also determine a target point (such as the midpoint) on the center line of the blood vessel in each target area as the corresponding ultrasound placement point for each cross-sectional area; the processor can also set the place with the largest blood vessel diameter (thickest blood vessel) in each target area as the corresponding ultrasound placement point for each cross-sectional area, such as determining a target point (such as the midpoint) on the diameter line with the largest blood vessel diameter in each target area as the corresponding ultrasound placement point for each cross-sectional area. This embodiment does not impose any restrictions on this.

[0104] Correspondingly, the method provided in this embodiment, after determining the corresponding ultrasound placement points for each slice region, can also perform ultrasound examination on all or some of the ultrasound placement points to obtain and display the arterial blood flow spectrum corresponding to the ultrasound placement points, thus completing the ultrasound examination of arterial blood flow in the corresponding slice region. For example, the processor can directly perform ultrasound examination on all ultrasound placement points to obtain and display the arterial blood flow spectrum of each slice region, realizing automatic ultrasound examination of arterial blood flow in multiple slice regions automatically triggered, to facilitate the operator's ultrasound examination work; the processor can also perform ultrasound examination on the ultrasound placement points corresponding to the blood flow ultrasound command according to the acquired blood flow ultrasound command, to obtain and display the arterial blood flow spectrum of the corresponding slice region, realizing automatic ultrasound examination of arterial blood flow in all or some slice regions manually triggered, so that the operator can manually trigger the automatic ultrasound examination of the ultrasound placement points in the slice region to be detected according to the actual situation.

[0105] Correspondingly, the processor can also select the section ultrasound region to be examined based on the acquired section ultrasound command. This command is used to select the section region for ultrasound examination. Ultrasound examination is performed at the target placement point within the ultrasound placement point, obtaining and displaying the arterial blood flow spectrum of the section region corresponding to the section ultrasound command. The number of ultrasound placement points in each section region of the blood flow scan image is no greater than one, and the target placement point is the ultrasound placement point within the section region corresponding to the section ultrasound command. In other words, the operator can select one or more section regions in the blood flow scan image to trigger the section ultrasound command, enabling the processor to perform ultrasound examination at the ultrasound placement point within the operator-selected section region, obtaining the arterial blood flow spectrum of these sections. This achieves automatic ultrasound examination of arterial blood flow in one or more section regions manually triggered by the operator. For example, the ultrasound device can be equipped with function buttons to trigger the section ultrasound command, allowing pulse Doppler examination (i.e., ultrasound examination) to be initiated on a single vascular structure, or pulse Doppler examination (i.e., ultrasound examination) to be initiated on multiple vascular structures simultaneously.

[0106] Furthermore, in this embodiment, the processor can display the arterial blood flow spectrum of the corresponding slice area and the arterial blood flow spectrum of the currently frozen slice area simultaneously, based on the acquired simultaneous display command, facilitating subsequent comparison and analysis by the operator. That is, the operator can first operate the ultrasound device to trigger a freeze command, controlling the processor to freeze the arterial blood flow spectrum of the currently displayed slice area; then, the operator can operate the ultrasound device to select a pre-saved arterial blood flow spectrum of the slice area to be displayed simultaneously, such as the arterial blood flow spectrum of the distal renal artery, renal segmental artery, and / or interlobar artery at the optimal time period, triggering the simultaneous display command to control the processor to display the arterial blood flow spectrum of the selected slice area and the arterial blood flow spectrum of the frozen slice area simultaneously. For example, the arterial blood flow spectrum of the frozen slice area can be displayed in the upper area of ​​the display interface, and the arterial blood flow spectrum of the selected slice area can be displayed in the lower area; or the arterial blood flow spectrum of the frozen slice area can be displayed in the left area of ​​the display interface, and the arterial blood flow spectrum of the selected slice area can be displayed in the right area. Correspondingly, the processor can freeze the arterial blood flow spectrum of the currently displayed section area according to the obtained freeze command; it can also save the arterial blood flow spectrum of the currently displayed or selected section area according to the obtained save command.

[0107] In summary, the ultrasound examination method for arterial blood flow provided by the embodiments of the present invention can analyze the blood flow scanning section images acquired by the ultrasound device from both grayscale and color image dimensions, thereby achieving accurate identification of arterial blood flow regions in each section region of the blood flow scanning section image, and thus improving the accuracy of ultrasound examination of arterial blood flow.
