Description

Technical Field

Background
The endometrial peristalsis wave refers to a mechanical wave generated by the uterine muscle layer contraction driving the endometrial peristalsis. The frequency, direction, strength, etc. of the peristaltic wave change with the change of the menstrual cycle, thereby assisting sperm transportation and embryo implantation, and being one of the important indexes for judging the receptivity of endometrium. Meanwhile, the uterine peristalsis rule is influenced by uterine diseases, so that the study on the peristalsis wave has potential value for auxiliary diagnosis of uterine lesions.
However, at present, there is no objective means for assisting clinical diagnosis of peristaltic waves, subjective judgment made by repeatedly observing acquired ultrasound films only by the naked eyes of doctors can be relied on, time consumption is long, friendliness is low, repeatability of operators is poor, peristaltic frequency and direction judged by different doctors are not always consistent, and an objective tool for assisting judgment is urgently needed. In addition, the lack of objective aids is a major impediment to further research and application of peristaltic waves. Therefore, the realization of the ultrasonic peristaltic wave detection function of the peristaltic waves can be qualitatively and quantitatively analyzed, and the method has important significance and great potential value for establishing a peristaltic wave evaluation standard system and assisting clinical evaluation.
Currently, there is a technology for displaying the propagation state of the peristaltic wave by using a space-time diagram. However, the frequency of the peristaltic waves is generally 2-4 times/minute, the peristaltic waves need to be collected for 30 seconds to 2 minutes when being checked, the time is too long, the patient is difficult to keep holding breath, and the doctor is easy to shake hands, so that the space-time diagram effect is poor, and the peristaltic waves are difficult to accurately judge.

First, an exemplary ultrasound measurement apparatus for implementing the display method of ultrasound image quality and a space-time diagram of the embodiment of the present application is described with reference to fig. 1.
Fig. 1 is a schematic structural block diagram of an exemplary ultrasound measurement apparatus 10 for implementing a display method of ultrasound image quality and a space-time diagram according to an embodiment of the present application. As shown in fig. 1, the ultrasonic measuring apparatus 10 may include an ultrasonic probe 100, a transmission/reception selection switch 101, a transmission/reception sequence controller 102, a processor 103, a display 104, and a memory 105. The transmission/reception sequence controller 102 may excite the ultrasound probe 100 to transmit an ultrasonic wave to a target object (measured object), and may also control the ultrasound probe 100 to receive an ultrasonic echo returned from the target object, thereby obtaining an ultrasonic echo signal/data. The processor 103 processes the ultrasound echo signals/data to obtain tissue related parameters and ultrasound images of the target object. Ultrasound images obtained by the processor 103 may be stored in the memory 105 and displayed on the display 104. The target object in the present application may be a human or an animal such as a veterinary animal, for example, a cat, a dog, a rabbit, and the like, and is not particularly limited herein.
In this embodiment, the display 104 of the ultrasonic measurement apparatus 10 may be a touch display screen, a liquid crystal display, or the like, or may be an independent display apparatus such as a liquid crystal display, a television, or the like, which is independent of the ultrasonic measurement apparatus 10, or may be a display screen on an electronic apparatus such as a mobile phone, a tablet computer, or the like.
In the embodiment of the present application, the memory 105 of the ultrasonic measurement apparatus 10 can be a flash memory card, a solid-state memory, a hard disk, or the like.
The embodiment of the present application further provides a computer-readable storage medium, where multiple program instructions are stored in the computer-readable storage medium, and after the multiple program instructions are called and executed by the processor 103, some or all of the steps in the method for displaying the quality of an ultrasound image and a space-time diagram in the various embodiments of the present application, or any combination of the steps in the method may be performed.
In one embodiment, the computer readable storage medium may be memory 105, which may be a non-volatile storage medium such as a flash memory card, solid state memory, hard disk, or the like.
In the embodiment of the present application, the processor 103 of the ultrasound measurement apparatus 10 may be implemented by software, hardware, firmware or a combination thereof, and may use a circuit, a single or multiple Application Specific Integrated Circuits (ASICs), a single or multiple general purpose integrated circuits, a single or multiple microprocessors, a single or multiple programmable logic devices, or a combination of the foregoing circuits or devices, or other suitable circuits or devices, so that the processor 103 may perform the corresponding steps of the display method of the ultrasound image quality and the space-time diagram in each embodiment.
The method for displaying the quality of the ultrasound image and the space-time diagram of the present application, which can be performed by the aforementioned ultrasound measuring apparatus 10, is described in detail below with reference to fig. 2 to 11.
FIG. 2 shows a schematic flow chart diagram of a method 200 for displaying ultrasound image quality and a spatiotemporal map, according to an embodiment of the present application. As shown in fig. 2, the method 200 for displaying the quality of the ultrasound image and the space-time diagram includes the following steps:
in step S210, an ultrasound image acquired for a period of time for a uterine region of a target object is acquired, and an image quality evaluation result of the ultrasound image is determined.
In step S220, a region of interest in the ultrasound image is determined, wherein the tissue region corresponding to the region of interest includes tissue generating a peristaltic wave.
In step S230, a space-time diagram of the region of interest is generated according to the position of the region of interest in each frame of ultrasound image, and the space-time diagram is used for characterizing the position change of the region of interest over time.
In step S240, an image quality evaluation result of at least one frame of the ultrasound image and the corresponding space-time diagram are displayed.
In an embodiment of the present application, ultrasound data may be acquired over a period of time, and ultrasound images may be generated accordingly over a period of time. For each frame of the obtained ultrasound images, an image quality evaluation result for each frame of the ultrasound images can be determined. In one example, the quality of each frame of ultrasound image may be determined each time the frame of ultrasound image is generated, or the quality of each frame of ultrasound image may be determined after a period of time of ultrasound images is obtained. In addition, the region of interest can be determined according to at least one frame of ultrasonic image, and a space-time diagram reflecting the position change of the region of interest along with time can be generated according to the position of the region of interest in each frame of ultrasonic image. In this embodiment, the tissue region to which the region of interest corresponds may be a region including tissue that generates peristaltic waves. Therefore, by displaying the generated space-time diagram, a user (e.g., a doctor) can know the propagation state of the endometrial peristaltic wave of the current target object (e.g., a patient) from the space-time diagram; in addition, together with the image quality information of the displayed ultrasound image, the user knows which parts of the space-time diagram are more effective (corresponding to the position condition of the region of interest in the ultrasound image with good image quality) and which parts are possible invalid or poor (corresponding to the position condition of the region of interest in the ultrasound image with poor image quality) according to the image quality information; based on the method, the user can mainly analyze the propagation state of the endometrial wriggling wave of the target object according to the effective part in the space-time diagram, so that the accuracy of an analysis result is improved, and the method is favorable for diagnosing the state of an illness more accurately.
In an embodiment of the present application, the result of evaluating the image quality of the ultrasound image (which may also be referred to as quality information of the ultrasound image) may include information related to a result of quality determination as to whether the image quality of the ultrasound image satisfies a preset requirement. That is, when the image quality of the ultrasound image satisfies the preset requirement, the image quality evaluation result of the ultrasound image is information; when the image quality of the ultrasound image does not meet the preset requirement, the image quality evaluation result of the ultrasound image is another information. In one example, when the image quality of a frame of ultrasound image meets a preset requirement, the image quality evaluation result of the ultrasound image can be represented as a first identifier; when the image quality of the frame of ultrasound image does not meet the preset requirement, the result of the image quality evaluation of the ultrasound image may be represented as a second identifier. Based on these two different pieces of information, the user can thus distinguish the effective portion and the ineffective portion in the space-time diagram, and analyze the propagation state of the endometrial wriggle wave of the target object from the effective portion.
In an embodiment of the present application, portions of the spatiotemporal image corresponding to ultrasound images whose image quality satisfies and does not satisfy the preset requirements may be displayed in a manner distinguished from each other, respectively, which may make the user clear the effective portion and the ineffective portion in the spatiotemporal image, thereby making the user directly ignore the ineffective portion and analyze only the effective portion to judge the propagation state of the endometrial wriggling wave of the target object. For example, in the space-time diagram, the brightness of the portion of the ultrasound image whose image quality does not satisfy the preset requirement is lower or blurred (described later in conjunction with fig. 3 and 4) relative to the portion of the ultrasound image whose image quality satisfies the preset requirement. In this example, when analyzing the space-time diagram, the user can directly ignore the darker or blurred portion, which not only improves the efficiency, but also improves the accuracy of the analysis result.
In an embodiment of the present application, the image quality evaluation result of the ultrasound image may be displayed on the ultrasound image (e.g., a grayscale image), may be displayed in a space-time diagram (described later in conjunction with fig. 3), and may be displayed on both (described later in conjunction with fig. 4). For example, the first identification information and the second identification information described above may be displayed at respective positions of the space-time diagram. In this example, when the image quality of a frame of ultrasound image satisfies a preset requirement, first identification information may be displayed at a position near a portion corresponding to the frame of ultrasound image on the space-time diagram; when the image quality of a frame of ultrasound image does not meet the preset requirement, second identification information may be displayed at a position near a portion corresponding to the frame of ultrasound image on the space-time diagram.
In addition, in the embodiment of the present application, in the space-time diagram, when the quality determination result of one frame of ultrasound image jumps relative to the quality determination result of the previous frame of ultrasound image, the same identification information is displayed in an interval corresponding to a plurality of consecutive frames of ultrasound images with the same quality determination result before the one frame of ultrasound image (described later with reference to fig. 3 and 4). In this embodiment, the quality determination result of each frame of ultrasound image is not displayed at the corresponding portion of the space-time diagram, but the same identification information is used for the portions with the same quality condition, and another identification information is displayed when the quality changes, so that the image quality information displayed on the space-time diagram is more concise, and the viewing experience of the user is improved.
In another embodiment of the present application, the result of the image quality evaluation of the ultrasound image may include information related to the result of the determination of the quality grade of the ultrasound image. In the embodiment, the quality of the ultrasonic image is graded, so that the effective degree of the corresponding space-time diagram part is graded, and a user can determine the space-time diagram part to be analyzed according to the effective degree of the space-time diagram, so that the accuracy of an analysis result can be further improved.
In an embodiment of the present application, whether the image quality of a frame of ultrasound image meets a preset requirement may be determined by at least one of the following ways (1) to (6): (1) judging whether the average motion amplitude of all the areas of one frame of ultrasonic image is higher than a preset threshold value, if so, judging that the quality does not meet the preset requirement; (2) judging whether the average motion amplitude (a curve with high echo in a section) of a uterine wall area in a frame of ultrasonic image is higher than a preset threshold value, if so, judging that the quality does not meet the preset requirement; (3) judging whether the average motion amplitude of partial areas (such as frames or lines) or all areas outside the uterus in one frame of ultrasonic image is higher than a preset threshold value, if so, judging that the quality does not meet the preset requirement; (4) judging whether the average motion amplitude of a selected area (such as a frame or a line) in the interior of the uterus (as far as possible from the position of the endometrium) outside the endometrium in one frame of ultrasonic image is higher than a preset threshold value, and if so, judging that the quality does not meet the preset requirement; (5) judging whether the average motion amplitude of the gravity center position of the endometrium in one frame of ultrasonic image is higher than a preset threshold value, if so, judging that the quality does not meet the preset requirement (because the gravity center of the whole endometrium cannot be greatly shifted due to severe endometrial peristalsis); (6) and judging whether the matching degree of the characteristics of the uterus in every two frames of ultrasonic images is lower than a preset threshold value, if so, judging that the quality does not meet the preset requirement.
That is, the average motion amplitude (or weighted average motion amplitude) of a preset region (such as the whole region, the uterine wall region, a part or whole region outside the uterus, a selected region inside the uterus outside the endometrium, the gravity center position of the endometrium, etc.) of one frame of the ultrasound image relative to the previous frame of the ultrasound image can be determined, and compared with a preset threshold, if the average motion amplitude is higher than the preset threshold, the image quality of the frame of the ultrasound image is not in accordance with the preset requirement. Or, whether the matching degree of the characteristics of the uterus in every two frames of ultrasonic images is lower than a preset threshold value or not can be judged, and if so, the judgment result is that the quality does not meet the preset requirement. Wherein the characteristics of the uterus may include at least one of: location of uterus, morphology of uterus and size of uterus.
Further, as described above, the image quality evaluation result of the ultrasound image may include information on the determination result of the quality grade of the ultrasound image. In this embodiment, the quality level may be higher, the smaller the average motion amplitude, the better the quality, by ranking the size of a preset region of one frame of ultrasound images (such as the entire region, the uterine wall region, a part or all of the region outside the uterus, a selected region inside the uterus outside the endometrium, the position of the center of gravity of the endometrium, etc.) relative to its average motion amplitude of the previous frame of ultrasound images. Similarly, the degree of match of the features of the uterus in each two frames of ultrasound images may be ranked, with a higher level of match and a higher level of quality.
An example of ultrasound image quality and a space-time diagram displayed in the method for displaying ultrasound image quality and a space-time diagram according to the embodiment of the present application is described below with reference to fig. 3 and 4.
Fig. 3 shows a time-space diagram of a region of interest (in this example, the region of interest is a line segment, and in other examples, the region of interest may be in other forms) manually selected (or automatically selected by the system) by a user after a period of ultrasound data acquisition is completed, and generated according to a position of the region of interest in each frame of ultrasound image during the period of time (the time-space diagram reflects a motion trajectory of the region of interest in the ultrasound image during the period of time). As shown in fig. 3, the horizontal axis of the space-time diagram is time, and the vertical axis is the position (of the region of interest in each frame of ultrasound image), so the space-time diagram is used to characterize the position change of the region of interest with time.
In addition, in fig. 3, the image quality evaluation result of the ultrasound image is presented in a space-time diagram, such as the five-star identifier and the one-star identifier in fig. 3 (which are only exemplary, and any other identification information may be used as long as different qualities can be distinguished, and is not limited to visual information, and may also be sound information, etc.), where the five-star identifier indicates that the quality of the ultrasound image in this period is good, and the one-star identifier indicates that the quality of the ultrasound image in this period is poor (to reduce the identifiers and improve the conciseness, the same identification information is displayed in the interval corresponding to the consecutive multi-frame ultrasound images with the same quality, as described above). Based on the identification information, the user can know that the space-time diagram part corresponding to the five-star identification is the effective part, and can analyze the propagation state of the endometrial wriggling wave of the target object according to the space-time diagram of the effective part. In addition, a star marks the whole corresponding space-time diagram part to be darkened (which is only exemplary, and any other way can be adopted as long as the space-time diagram parts corresponding to different qualities can be distinguished from each other), so that the user can more clearly ignore the space-time diagram of the part and does not adopt the part to analyze so as not to obtain inaccurate results.
In general, the example shown in fig. 3 displays ultrasound image quality information on a space-time diagram, and thus may be referred to as a quality space-time diagram, and since it is a space-time diagram generated after the acquisition of data is completed, the quality space-time diagram may be referred to herein as a static quality space-time diagram, and the space-time diagram generated in real-time by the real-time acquisition of data, which will be described later, may be referred to as a dynamic (quality) space-time diagram, as compared to the real-time generation of a space-time diagram by the real-time acquisition of data, which will be described later.
Fig. 4 shows an example of a display interface that displays ultrasound image quality information on both the ultrasound image and the space-time diagram. As shown in fig. 4, the upper half part shows a frame of ultrasound grayscale image, the upper right corner shows the quality information (indicated by five stars) of the frame of ultrasound image, and the lower half part is the same space-time diagram as in fig. 3. In this example, the upper half of fig. 4 may dynamically display frames of ultrasound images generated over time and their respective quality information, and the lower half may display a static quality space-time map after all ultrasound data acquisitions are complete (after all frames of ultrasound images are complete).
The above exemplarily describes a display method of an ultrasound image quality and a space-time diagram according to an embodiment of the present application.

As shown in fig. 5, the method 500 for displaying the quality of the ultrasound image and the space-time diagram includes the following steps:
in step S510, the ultrasound probe is controlled to emit a first ultrasound wave for a uterine region of a target object, and receive an ultrasound echo based on the first ultrasound wave, resulting in a first ultrasound echo signal.
In step S520, a first ultrasound image is generated in real time according to the first ultrasound echo signal, and an image quality evaluation result of the first ultrasound image is determined.
In step S530, a region of interest in the first ultrasound image is determined, and a space-time diagram of the region of interest is generated according to a position of the region of interest in the first ultrasound image, where a tissue region corresponding to the region of interest includes tissue that produces peristaltic waves, and the space-time diagram is used to characterize a position change condition of the region of interest over time.
In step S540, the ultrasound probe is controlled to emit a second ultrasound wave to the uterine region, and receive an ultrasound echo based on the second ultrasound wave, resulting in a second ultrasound echo signal.
In step S550, a second ultrasound image is generated in real time according to the second ultrasound echo signal, an image quality evaluation result of the second ultrasound image is determined, and the space-time diagram is updated according to the position of the region of interest in the second ultrasound image.
In step S560, the result of the image quality evaluation of the generated ultrasound image and the corresponding space-time diagram are dynamically displayed.
The method 500 for displaying the ultrasound image quality and the space-time diagram according to the embodiment of the present application is similar to the method 200 for displaying the ultrasound image quality and the space-time diagram according to the embodiment of the present application, except that the method 200 for displaying the ultrasound image quality and the space-time diagram according to the embodiment of the present application generates a static space-time diagram at a time after ultrasound data is acquired for a period of time, and the method 500 for displaying the ultrasound image quality and the space-time diagram according to the embodiment of the present application generates the space-time diagram in real time according to the ultrasound data acquired in real time, and the space-time diagram is updated in real time along with the acquisition of the ultrasound data (data of the space-time diagram is increased along with the passage of time represented by the horizontal axis) and is dynamically displayed.
Similar to the display method 200 of the ultrasound image quality and the space-time diagram according to the embodiment of the present application, the display method 500 of the ultrasound image quality and the space-time diagram according to the embodiment of the present application can know the propagation state of the endometrial wriggling wave of the current target object (e.g., a patient) from the space-time diagram by displaying the generated space-time diagram; in addition, together with the image quality information of the displayed ultrasound image, the user knows which parts of the space-time diagram are more effective (corresponding to the position condition of the region of interest in the ultrasound image with good image quality) and which parts are possible invalid or poor (corresponding to the position condition of the region of interest in the ultrasound image with poor image quality) according to the image quality information; based on the method, the user can mainly analyze the propagation state of the endometrial wriggling wave of the target object according to the effective part in the space-time diagram, so that the accuracy of an analysis result is improved, and the method is favorable for diagnosing the state of an illness more accurately.
Similar to the display method 200 of the ultrasound image quality and the space-time diagram according to the embodiment of the application, in the display method 500, the image quality evaluation result of the ultrasound image may include information related to a quality determination result of whether the image quality of the ultrasound image satisfies a preset requirement. For example, when the image quality of a frame of ultrasound image meets a preset requirement, the image quality evaluation result of the ultrasound image may include first identification information; when the image quality of the frame of ultrasound image does not meet the preset requirement, the image quality evaluation result of the ultrasound image may include the second identification information. Based on these two different pieces of information, the user can thus distinguish the effective portion and the ineffective portion in the space-time diagram, and analyze the propagation state of the endometrial wriggle wave of the target object from the effective portion.
Further, the portions of the spatiotemporal map corresponding to the ultrasound images whose image quality satisfies and does not satisfy the preset requirements may be displayed in a manner distinguished from each other, respectively, which may make the effective portion and the ineffective portion in the spatiotemporal map obvious to the user, thereby making the user directly ignore the ineffective portion and analyze only the effective portion to judge the propagation state of the endometrial wriggling wave of the target object. For example, in the space-time diagram, the brightness of the portion of the ultrasound image whose image quality does not satisfy the preset requirement is lower or blurred relative to the portion of the ultrasound image whose image quality satisfies the preset requirement.
The result of the image quality evaluation of the ultrasound image may be displayed on the ultrasound image, may be displayed on a space-time diagram, or may be displayed on both of them. When the image quality evaluation result of the ultrasonic image is displayed in the space-time diagram, and when the quality judgment result of one frame of ultrasonic image jumps relative to the quality judgment result of the previous frame of ultrasonic image, the same identification information is displayed in the interval corresponding to the continuous multi-frame ultrasonic image with the same quality judgment result before the one frame of image, so that the image quality information displayed on the space-time diagram is more concise, and the viewing experience of a user is improved. A
The average motion amplitude (or weighted average motion amplitude) of a preset area (such as the whole area, the uterine wall area, a part or whole area outside the uterus, a selected area inside the uterus outside the endometrium, the gravity center position of the endometrium and the like) of one frame of the ultrasonic image relative to the previous frame of the ultrasonic image can be determined, the average motion amplitude is compared with a preset threshold value, and if the average motion amplitude is higher than the preset threshold value, the image quality of the frame of the ultrasonic image is not in accordance with the preset requirement. Or, whether the matching degree of the features of the uterus in each two frames of ultrasound images is lower than a preset threshold value or not can be judged, and if yes, the quality is judged not to meet the preset requirement. Wherein the characteristics of the uterus may include at least one of: location of uterus, morphology of uterus and size of uterus.
Further, the image quality evaluation result of the ultrasound image may include information related to the determination result of the quality grade of the ultrasound image. Based on this, the preset regions of one frame of ultrasound image (such as the whole region, the uterine wall region, part or whole region outside the uterus, selected region inside the uterus outside the endometrium, the position of the center of gravity of the endometrium, etc.) can be graded with respect to the magnitude of their average motion amplitude in the previous frame of ultrasound image, with the smaller the average motion amplitude, the better the quality and the higher the quality grade. Similarly, the degree of matching of the features of the uterus in each two frames of ultrasound images can be ranked, with a higher degree of matching and a higher quality ranking. In the embodiment, the quality of the ultrasonic image is graded, so that the effective degree of the corresponding space-time diagram part is graded, and a user can determine the space-time diagram part to be analyzed according to the effective degree of the space-time diagram, so that the accuracy of an analysis result can be further improved.
An example of the ultrasound image quality and the space-time diagram displayed in the method 500 for displaying the ultrasound image quality and the space-time diagram according to the embodiment of the present application is described below with reference to fig. 6 and 7.
Fig. 6 shows a dynamically displayed space-time diagram, with a black dotted line corresponding to the current time. That is to say, during the process of acquiring the ultrasound data, the position of the region of interest in each frame of ultrasound image is synchronously updated and displayed in the space-time diagram, when the data acquisition is completed, the space-time diagram is updated, and the updated space-time diagram displays the position change condition of the region of interest along with the time within the period of acquiring the data.
In addition, in fig. 6, the image quality evaluation result of the ultrasound image is presented in a space-time diagram, such as the five-star identifier and the one-star identifier in fig. 6 (which are only exemplary, and any other identification information may be used as long as different qualities can be distinguished, and is not limited to visual information, and may also be sound information, etc.), where the five-star identifier indicates that the quality of the ultrasound image in this period is good, and the one-star identifier indicates that the quality of the ultrasound image in this period is poor (to reduce the identifiers and improve the conciseness, the same identification information is displayed in the interval corresponding to the consecutive multi-frame ultrasound images with the same quality, as described above). Based on the identification information, the user can know that the space-time diagram part corresponding to the five-star identification is the effective part, and can analyze the propagation state of the endometrial wriggling wave of the target object according to the space-time diagram of the effective part. In addition, the whole space-time diagram part corresponding to the star mark is darkened (which is only exemplary, and any other way can be adopted as long as the space-time diagram parts corresponding to different qualities can be distinguished from each other), so that the user can more clearly ignore the space-time diagram of the part, and the part of the space-time diagram is not adopted for analysis so as not to obtain inaccurate results.
In general, the example shown in FIG. 6 displays ultrasound image quality information on a space-time diagram, and thus may be referred to as a quality space-time diagram, and since the space-time diagram is generated in real-time as real-time acquisition data, the quality space-time diagram herein may be referred to as a dynamic quality space-time diagram, as opposed to the static quality space-time diagram described above.
Fig. 7 shows an example of a display interface that displays ultrasound image quality information on both the ultrasound image and the space-time diagram. As shown in fig. 7, the upper half part shows a frame of ultrasound gray scale image, the upper right corner shows quality information (indicated by five stars) of the frame of ultrasound image, and the lower half part is a space-time diagram similar to fig. 6. In this example, the upper half of fig. 7 may dynamically display frames of ultrasound images generated over time and their respective quality information, and the lower half may dynamically display a dynamic quality space-time diagram. The quality space-time diagram is generated and dynamically displayed in real time, and a user can adjust the ultrasonic data acquisition operation (such as adjusting the emission parameters of a probe) by the dynamic quality space-time diagram to obtain ultrasonic data with better quality, so that a space-time diagram with better effect is obtained.
The above exemplarily describes a display method of an ultrasound image quality and a space-time diagram according to another embodiment of the present application.
In the above embodiments, it is mainly described that the time-space diagram of the region of interest is generated according to the position of the region of interest in each frame of ultrasound image.

That is, the space-time diagram may also reflect motion information of the region of interest, such as a motion trajectory of the region of interest in the ultrasound image over a period of time.
Based on the above description, the display methods 200 and 500 of the ultrasound image quality and the spatiotemporal map according to the embodiments of the present application display the spatiotemporal map representing the temporal change of the region of interest (including the tissue region generating the peristaltic wave) in the ultrasound image and display the image quality evaluation result of the ultrasound image, so that the doctor can determine the validity of the spatiotemporal map based on the image quality of the ultrasound image, and further analyze the propagation state of the endometrial peristaltic wave of the target object according to the valid portion in the spatiotemporal map, thereby improving the accuracy of the analysis result.
