Description

Technical Field

[0001] This application relates to the field of medical technology, and in particular to a method, apparatus, system, computer equipment, storage medium, and computer program product for the synchronous detection of medical ultrasound images and electrocardiogram signals. Background Technology

[0002] Echocardiography and electrocardiogram (ECG) signals are both important tools for cardiac examination. Currently, ultrasound diagnostic equipment typically possesses both functions simultaneously (with a high degree of synchronization between the images and electrical signals) to provide a more comprehensive view of the heart's condition.

[0003] Currently, clinical trials are commonly used to determine whether the synchronization performance between the two functions meets the requirements, as there is a lack of engineered testing equipment. If these two functions are applied to a normal human body, experienced personnel can determine whether the synchronization between the two functions is normal by comparing the heartbeat status displayed on imaging with the characteristics of the electrocardiogram signal (QRS waveform).

[0004] However, this method of visually observing whether the heartbeat state is consistent with the characteristics of the electrocardiogram signal cannot accurately detect the synchronization performance between cardiac ultrasound images and electrocardiogram signals. Summary of the Invention

[0044] The image displays the observed object in periodic motion, as well as the waveform image of the electrocardiogram corresponding to the periodic electrocardiogram signal.

[0045] Based on the distance between the ECG data update point at the detection time and the previous QRS peak in the ECG signal waveform image, and the distance between two adjacent QRS peaks at the detection time, the relative relationship of ECG data distances is determined.

[0046] Based on the distance between the observed object's relative starting position and the reciprocating motion range in the observed object image at the detection time, the relative relationship of the object's motion distance is determined;

[0047] Based on the relative distance relationship of the electrocardiogram data and the relative distance relationship of the object's movement, the synchronization performance between the ultrasound image and the electrocardiogram signal of the ultrasound device under test is detected.

[0048] Sixthly, this application also provides a computer program product. The computer program product includes a computer program that, when executed by a processor, performs the following steps:

[0049] The image displays the observed object in periodic motion, as well as the waveform image of the electrocardiogram corresponding to the periodic electrocardiogram signal.

[0050] Based on the distance between the ECG data update point at the detection time and the previous QRS peak in the ECG signal waveform image, and the distance between two adjacent QRS peaks at the detection time, the relative relationship of ECG data distances is determined.

[0051] Based on the distance between the observed object's relative starting position and the reciprocating motion range in the observed object image at the detection time, the relative relationship of the object's motion distance is determined;

[0052] Based on the relative distance relationship of the electrocardiogram data and the relative distance relationship of the object's movement, the synchronization performance between the ultrasound image and the electrocardiogram signal of the ultrasound device under test is detected.

[0053] The aforementioned method, apparatus, system, computer equipment, storage medium, and computer program product for synchronous detection of medical ultrasound images and electrocardiogram (ECG) signals are applied to the ultrasound device under test. The ultrasound device under test is electrically connected to an ECG simulator. The periodic ECG signal generated by the ECG simulator is used to drive the observed object to perform reciprocating motion within the same period. By displaying the image of the observed object in periodic motion and the ECG signal waveform image corresponding to the periodic ECG signal, the relative relationship of ECG data distance is determined based on the distance between the ECG data update point at the detection time and the previous QRS peak, and the distance between two adjacent QRS peaks at the detection time in the ECG signal waveform image. The relative relationship of object motion distance is determined based on the distance between the relative starting position of the observed object at the detection time and the reciprocating motion range distance in the observed object image. Based on the relative relationship of ECG data distance and the relative relationship of object motion distance, the synchronization performance between the ultrasound image and the ECG signal of the ultrasound device under test is detected.

[0054] Thus, based on the distance between the ECG data update point and the previous QRS peak at the detection time, and the distance between two adjacent QRS peaks at the detection time, in the ECG signal waveform image displayed by the ultrasound device under test, the relative distance relationship of the ECG data can be efficiently and accurately determined, obtaining the update progress of the ECG signal within one cycle at the detection time, thereby determining the ECG signal characteristics at the detection time. Similarly, based on the distance between the observation object's relative starting position and the reciprocating motion range in the image of the observed object at the detection time, the relative distance relationship of the object's motion can be efficiently and accurately determined, obtaining the motion progress of the observed object within one cycle at the detection time. The periodic ECG signal generated by the ECG simulator can drive the observed object to perform reciprocating motion within the same cycle. By detecting the observed object through the ultrasound device under test, the cardiac pulsation state at the detection time can be characterized by the motion progress of the observed object within one cycle at the detection time. When the synchronization performance between the ultrasound image and the electrocardiogram (ECG) signal of the ultrasound device under test is better, the ECG signal characteristics and heart pulsation state at the same detection time will be more consistent. Therefore, by using the relative relationship between the distance of ECG data and the relative relationship between the distance of the object's movement at the same detection time, the synchronization performance between the ultrasound image and the ECG signal of the ultrasound device under test can be detected more accurately.

[0062] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0063] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0064] In one embodiment, such as Figure 1 As shown, a method for synchronous detection of medical ultrasound images and electrocardiogram signals is provided. This embodiment illustrates the application of this method to the ultrasound device under test. In this embodiment, the method includes the following steps:

[0065] Step S110: Display the image of the observed object with periodic motion and the waveform image of the electrocardiogram corresponding to the periodic electrocardiogram signal.

[0066] The ultrasound device under test is electrically connected to the electrocardiogram simulator.

[0067] Among them, the periodic electrocardiogram signals generated by the electrocardiogram simulator are used to drive the observed object to perform reciprocating motion in the same period.

[0068] Among them, the ultrasonic device to be tested is the ultrasonic device that needs to be tested synchronously.

[0069] In this setup, the ultrasonic probe of the ultrasonic device under test is placed on the object being observed.

[0070] Among them, the electrocardiogram (ECG) signal waveform image is the ECG waveform image corresponding to the periodic ECG signals generated by the ECG simulator.

[0071] Among them, the observed object image is the ultrasound image corresponding to the observed object that is performing reciprocating motion in the same period as the periodic electrocardiogram signal.

[0072] In practice, the display of the ultrasound device under test can show the waveform image of the electrocardiogram (ECG) signal that matches the periodic ECG signal, as well as the image of the observation object that is performing reciprocating motion in the same period as the periodic ECG signal.

[0073] Specifically, the periodic electrocardiogram (ECG) signal generated by the ECG simulator drives the observed object to perform reciprocating motion in the same period. After the ultrasound probe of the ultrasound device under test is placed on the observed object, and the imaging function and ECG (electrocardiogram) imaging function of the ultrasound device under test are turned on, the image of the periodically moving observed object and the ECG signal waveform image corresponding to the periodic ECG signal emitted by the ECG simulator can be displayed on the monitor at the same time.

[0074] Step S120: Determine the relative distances of the ECG data based on the distance between the ECG data update point at the detection time and the previous QRS peak, and the distance between two adjacent QRS peaks at the detection time in the ECG signal waveform image.

[0075] The detection time can be a specific moment during the movement of the observed object or during the update process of the electrocardiogram signal.

[0076] Among them, the ECG data update point is used to record the update of the sampling points of the ECG signal at the detection time.

[0077] In practice, the ultrasound device under test can obtain the relative relationship of ECG data distances based on the distance between the ECG data update point at the detection time and the previous QRS peak, as well as the distance between two adjacent QRS peaks at the detection time, in the ECG signal waveform image. Based on the relative relationship of ECG data distances, the update progress of the ECG signal within one cycle at the detection time can be determined.

[0078] Step S130: Based on the distance between the starting position of the relative motion of the observed object and the distance of the reciprocating motion range in the image of the observed object at the detection time, determine the relative relationship of the object's motion distance.

[0079] The reciprocating motion range distance is the total distance between one extreme position and another when the observed object is performing periodic reciprocating motion. One of the extreme positions can be the starting position.

[0080] For example, when an observed object is making periodic reciprocating motion along a horizontal direction, the extreme positions can refer to the leftmost or rightmost positions. It is understandable that the direction of motion of the observed object is not limited to the horizontal direction.

[0081] In practice, the ultrasound device under test can determine the relative distance of the object's motion based on the distance between the starting position of the object's relative motion and the distance of the reciprocating motion range in the image of the object at the time of detection. Based on the relative distance of the object's motion, the device can determine the motion progress of the object within one cycle at the time of detection.

[0082] Step S140: Based on the relative distance relationship of ECG data and the relative distance relationship of object movement, detect the synchronization performance between the ultrasound image and ECG signal of the ultrasound device under test.

[0083] In practice, the ultrasound device under test can detect the synchronization performance between the ultrasound image and the electrocardiogram (ECG) signal based on the relative distance relationship between ECG data and the relative distance of the object's movement. Specifically, since the periodic ECG signal generated by the ECG simulator can drive the observed object to perform reciprocating motion within the same period, the ultrasound device under test can detect the observed object, and thus characterize the heartbeat state at the detection time by observing the progress of the observed object's movement within one cycle. The better the synchronization performance between the ultrasound image and the ECG signal of the ultrasound device under test, the more consistent the ECG signal characteristics and heartbeat state will be at the same detection time. Therefore, the synchronization performance between the ultrasound image and the ECG signal of the ultrasound device under test can be detected by using the relative distance relationship between the ECG data and the relative distance of the object's movement at the same detection time.

[0084] It is understood that the above-mentioned method for synchronous detection of medical ultrasound images and electrocardiogram signals can be applied not only to the ultrasound device under test, but also to other computer devices. The computer device can acquire the periodically moving image of the observed object displayed on the monitor of the ultrasound device under test and the electrocardiogram waveform image corresponding to the periodic electrocardiogram signal, and execute the steps of the above-described method for synchronous detection of medical ultrasound images and electrocardiogram signals.

[0085] In the above-mentioned method for synchronous detection of medical ultrasound images and electrocardiogram (ECG) signals, the ultrasound device under test is electrically connected to an ECG simulator; the periodic ECG signal generated by the ECG simulator is used to drive the observed object to perform reciprocating motion within the same period; the image of the observed object in periodic motion and the ECG signal waveform image corresponding to the periodic ECG signal are displayed; the relative relationship of ECG data distance is determined based on the distance between the ECG data update point and the previous QRS peak at the detection time, and the distance between two adjacent QRS peaks at the detection time in the ECG signal waveform image; the relative relationship of object motion distance is determined based on the distance between the relative starting position of the observed object at the detection time and the reciprocating motion range distance in the observed object image; the synchronization performance between the ultrasound image and the ECG signal of the ultrasound device under test is detected based on the relative relationship of ECG data distance and the relative relationship of object motion distance.

[0086] Thus, based on the distance between the ECG data update point and the previous QRS peak at the detection time, and the distance between two adjacent QRS peaks at the detection time, in the ECG signal waveform image displayed by the ultrasound device under test, the relative distance relationship of the ECG data can be efficiently and accurately determined, obtaining the update progress of the ECG signal within one cycle at the detection time, thereby determining the ECG signal characteristics at the detection time. Similarly, based on the distance between the observation object's relative starting position and the reciprocating motion range in the image of the observed object at the detection time, the relative distance relationship of the object's motion can be efficiently and accurately determined, obtaining the motion progress of the observed object within one cycle at the detection time. The periodic ECG signal generated by the ECG simulator can drive the observed object to perform reciprocating motion within the same cycle. By detecting the observed object through the ultrasound device under test, the cardiac pulsation state at the detection time can be characterized by the motion progress of the observed object within one cycle at the detection time. When the synchronization performance between the ultrasound image and the electrocardiogram (ECG) signal of the ultrasound device under test is better, the ECG signal characteristics and heart pulsation state at the same detection time will be more consistent. Therefore, by using the relative relationship between the distance of ECG data and the relative relationship between the distance of the object's movement at the same detection time, the synchronization performance between the ultrasound image and the ECG signal of the ultrasound device under test can be detected more accurately.

[0087] In one embodiment, detecting the synchronization performance between the ultrasound image and the electrocardiogram signal of the ultrasound device under test based on the relative relationship between the distance of the electrocardiogram data and the relative relationship between the distance of the object's movement includes: detecting the synchronization performance between the ultrasound image and the electrocardiogram signal of the ultrasound device under test based on the difference between the relative relationship between the distance of the object's movement and the relative relationship between the distance of the electrocardiogram data.

[0088] In practice, during the process of detecting the synchronization performance between the ultrasound image and the electrocardiogram signal of the ultrasound device under test based on the relative relationship between the distance of the electrocardiogram data and the relative relationship between the distance of the object's movement, the ultrasound device under test can detect the synchronization performance between the ultrasound image and the electrocardiogram signal of the ultrasound device under test based on the difference between the relative relationship between the distance of the object's movement and the relative relationship between the distance of the electrocardiogram data.

[0089] The technical solution of this embodiment detects the synchronization performance between the ultrasound image and the electrocardiogram (ECG) signal of the ultrasound device under test by based on the difference between the relative relationship of the object's movement distance and the relative relationship of the ECG data distance. Thus, the better the synchronization performance between the ultrasound image and the ECG signal of the ultrasound device under test, the more consistent the ECG signal characteristics and heartbeat state at the same detection moment will be. Since the ECG signal characteristics at the detection moment can be determined based on the relative relationship of the ECG data distance, and the heartbeat state at the detection moment can be determined based on the relative relationship of the object's movement distance, the synchronization performance between the ultrasound image and the ECG signal of the ultrasound device under test can be detected more accurately based on the difference between the relative relationship of the object's movement distance and the relative relationship of the ECG data distance.

[0090] In one embodiment, detecting the synchronization performance between the ultrasound image and the ECG signal of the ultrasound device under test based on the difference between the relative ratio of the object's motion distance and the relative ratio of the ECG data distance includes: obtaining a distance ratio difference based on the difference between the object's motion distance ratio and the ECG data distance ratio; the object's motion distance ratio is used to quantify the relative relationship of the object's motion distance; the ECG data distance ratio is used to quantify the relative relationship of the ECG data distance; the distance ratio difference is used to quantify the difference between the relative relationship of the object's motion distance and the relative relationship of the ECG data distance; determining a synchronization performance quantization value of the ultrasound device under test based on the distance ratio difference; and the synchronization performance quantization value is used to quantify the synchronization performance between the ultrasound image and the ECG signal of the ultrasound device under test.

[0091] In practice, during the process of detecting the synchronization performance between the ultrasound image and the ECG signal of the ultrasound device under test (UTT) based on the difference between the relative ratio of the object's motion distance and the relative ratio of the ECG data distance, the UDT can obtain a distance ratio difference based on the difference between the object's motion distance ratio and the ECG data distance ratio. Here, the object's motion distance ratio is a value used to quantify the relative relationship of the object's motion distance; the ECG data distance ratio is a value used to quantify the relative relationship of the ECG data distance. Thus, the distance ratio difference can serve as a value used to quantify the difference between the relative relationship of the object's motion distance and the relative relationship of the ECG data distance. Therefore, the UDT can determine a value used to quantify the synchronization performance between the ultrasound image and the ECG signal based on the distance ratio difference, and this value can be used as a quantified synchronization performance value.

[0092] The technical solution of this embodiment obtains a distance ratio difference by comparing the ratio of the object's motion distance to the ratio of the ECG data distance. The object's motion distance ratio is used to quantify the relative relationship of the object's motion distance; the ECG data distance ratio is used to quantify the relative relationship of the ECG data distance; the distance ratio difference is used to quantify the difference between the relative relationship of the object's motion distance and the relative relationship of the ECG data distance; based on the distance ratio difference, a quantified value of the synchronization performance of the ultrasound device under test is determined; this quantified value is used to quantify the synchronization performance between the ultrasound image and the ECG signal of the ultrasound device under test. Thus, because the better the synchronization performance between the ultrasound image and the ECG signal of the ultrasound device under test, the more consistent the ECG signal characteristics and heartbeat state at the same detection moment will be, and the ECG signal characteristics at the detection moment can be determined based on the relative relationship of the ECG data distance, while the heartbeat state at the detection moment can be determined based on the relative relationship of the object's motion distance. By measuring the difference between the ratio of the relative distances of the moving objects and the ratio of the relative distances of the electrocardiogram (ECG) data, that is, by measuring the difference in distance ratios used to quantify the differences between the relative distances of the moving objects and the relative distances of the ECG data, the degree of synchronization between the ECG signal characteristics and the heartbeat state at the same detection moment can be quantified more accurately. Thus, based on the synchronization performance quantification value obtained from the distance ratio difference, the synchronization performance between the ultrasound image and the ECG signal of the ultrasound device under test can be quantified more accurately, so as to quantitatively detect the synchronization performance between the ultrasound image and the ECG signal of the ultrasound device under test.

[0093] In one embodiment, determining the synchronization performance quantification value of the ultrasonic device under test based on the distance ratio difference includes: obtaining the target distance ratio difference based on the absolute value of the distance ratio difference; and using the target distance ratio difference as the synchronization performance quantification value.

[0094] Among them, the target distance ratio difference (i.e., the synchronization performance quantification value) has a negative correlation with synchronization performance. That is, the smaller the value of the synchronization performance quantification value, the better the synchronization performance; the larger the value of the synchronization performance quantification value, the worse the synchronization performance.

[0095] In practice, during the process of determining the quantification value of the synchronization performance of the ultrasonic device under test based on the distance ratio difference, the ultrasonic device under test can obtain the target distance ratio difference based on the absolute value of the distance ratio difference. That is, the ultrasonic device under test can use the absolute value of the distance ratio difference as the target distance ratio difference, and thus, the ultrasonic device under test can use the target distance ratio difference as the quantification value of synchronization performance.

[0096] The technical solution of this embodiment obtains the target distance ratio difference based on the absolute value of the distance ratio difference; this target distance ratio difference is then used as a quantification value of synchronization performance. Thus, by using the absolute value of the distance ratio difference, the synchronization performance between the ultrasound image and the electrocardiogram signal of the ultrasound device under test can be quantified more accurately.

[0097] In one embodiment, the relative relationship of ECG data distances is determined based on the distance between the ECG data update point at the detection time and the previous QRS peak, and the distance between two adjacent QRS peaks at the detection time, in the ECG signal waveform image. This includes: using the distance between the ECG data update point at the detection time and the previous QRS peak as the ECG data movement distance; using the distance between two adjacent QRS peaks at the detection time as the ECG peak distance; obtaining the ECG data distance ratio based on the ratio of the ECG data movement distance to the ECG peak distance; and using the ECG data distance ratio to quantify the relative relationship of ECG data distances.

[0098] The distance between the spikes is directly proportional to the heart rate value set in the ECG simulator.

[0099] In practice, when the ultrasound device under test determines the relative distances of ECG data based on the distance between the ECG data update point at the detection time and the previous QRS peak, as well as the distance between two adjacent QRS peaks at the detection time, the distance between the ECG data update point at the detection time and the previous QRS peak can be used as the ECG data movement distance; simultaneously, the distance between two adjacent QRS peaks at the detection time can be used as the ECG peak distance. Thus, the ultrasound device under test can obtain the ECG data distance ratio based on the ratio of the ECG data movement distance to the ECG peak distance. That is, the ratio of the ECG data movement distance to the ECG peak distance can be used as the ECG data distance ratio. This ECG data distance ratio quantifies the relative distances of the ECG data, thereby determining the update progress of the ECG signal within one cycle at the detection time.

[0100] For the ease of understanding of those skilled in the art, Figure 2 A schematic diagram of an electrocardiogram (ECG) signal waveform is provided. For example... Figure 2 As shown, m2 is the distance between the ECG data update point at the detection time and the previous QRS peak, i.e., the distance the ECG data moves; m1 is the distance between two adjacent QRS peaks at the detection time, i.e., the distance between ECG peaks.

[0101] The technical solution of this embodiment uses the distance between the ECG data update point at the detection time and the previous QRS peak as the ECG data movement distance; the distance between two adjacent QRS peaks at the detection time is used as the ECG peak distance; and the ECG data distance ratio is obtained by calculating the ratio of the ECG data movement distance to the ECG peak distance. This ECG data distance ratio is used to quantify the relative relationship of ECG data distances. Thus, by using the ECG data distance ratio obtained from the distance ratio, the relative relationship of ECG data distances can be quantified more accurately.

[0102] In one embodiment, the relative relationship of the object's motion distance is determined based on the distance between the observed object's relative motion start position at the detection time and the reciprocating motion range distance in the observed object image. This includes: using the distance between the observed object's relative motion start position at the detection time as the relative object motion distance; obtaining the object motion distance ratio based on the ratio of the relative object motion distance to the reciprocating motion range distance; and using the object motion distance ratio to quantify the relative relationship of the object's motion distance.

[0103] In practice, when the ultrasound device under test determines the relative distance of the object's motion based on the distance from the object's initial position relative to its motion in the image at the detection time, as well as the distance of its reciprocating motion range, the ultrasound device under test can use the distance from the object's initial position relative to its motion in the image at the detection time as the relative distance of the object's motion. Thus, the ultrasound device under test can obtain the object's motion distance ratio based on the ratio of the relative distance of the object's motion to the distance of its reciprocating motion range. That is, by using the ratio of the relative distance of the object's motion to the distance of its reciprocating motion range as the object's motion distance ratio, the relative distance of the object's motion can be quantified to determine the progress of the observed object's motion within one cycle at the detection time.

[0104] The technical solution of this embodiment uses the distance between the observed starting position of the object's relative motion at the detection time as the relative distance of the object's motion; it obtains the object motion distance ratio based on the ratio of the relative distance of the object's motion to the distance of the reciprocating motion range; the object motion distance ratio is used to quantify the relative relationship of the object's motion distance. Thus, by using the object motion distance ratio obtained from the distance ratio, the relative relationship of the object's motion distance can be quantified more accurately.

[0105] In another embodiment, such as Figure 3 As shown, a method for synchronous detection of medical ultrasound images and electrocardiogram signals is provided. Taking the application of this method to the ultrasound device under test as an example, the method includes the following steps:

[0106] Step S302: Display the image of the observed object with periodic motion and the waveform image of the electrocardiogram corresponding to the periodic electrocardiogram signal.

[0107] Step S304: The distance between the ECG data update point at the detection time and the previous QRS peak is taken as the ECG data movement distance.

[0108] Step S306: The distance between two adjacent QRS peaks at the detection time is taken as the ECG peak distance.

[0109] Step S308: Obtain the ECG data distance ratio based on the ratio of the ECG data movement distance to the ECG peak distance.

[0110] Step S310 involves observing the distance between the starting position of the relative motion of the object at the detection time, and using this distance as the relative distance of the object's motion.

[0111] Step S312: Obtain the object movement distance ratio based on the ratio of the relative distance of the object's movement to the distance of the reciprocating movement range.

[0112] Step S314: Obtain the distance ratio difference based on the difference between the object's motion distance ratio and the ECG data distance ratio.

[0113] Step S316: Determine the quantification value of the synchronization performance of the ultrasonic device under test based on the distance ratio difference.

[0114] It should be noted that the specific limitations of the above steps can be found in the above description of the specific limitations of a method for synchronous detection of medical ultrasound images and electrocardiogram signals.

[0115] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0116] Based on the same inventive concept, this application also provides a medical ultrasound image and electrocardiogram (ECG) signal synchronization detection system for implementing the above-mentioned method for synchronous detection of medical ultrasound images and ECG signals. The medical ultrasound image and ECG signal synchronization detection system includes an ultrasound device under test, an ECG simulator, an ECG signal processing module (ECG signal processing module), a motor drive module, and a motor; the ultrasound probe of the ultrasound device under test is placed on the object being observed.

[0117] The ultrasound device under test, the electrocardiogram simulator, the electrocardiogram signal processing module, the motor drive module, and the motor are electrically connected in sequence; the ultrasound device under test and the electrocardiogram signal processing module are connected to the electrocardiogram simulator through different lead signals;

[0118] An electrocardiogram (ECG) simulator is used to generate periodic ECG signals and send them to the ECG signal processing module.

[0119] The electrocardiogram (ECG) signal processing module is used to receive periodic ECG signals and convert them into motor control signals with the same periodicity as the periodic ECG signals.

[0120] The electrocardiogram signal processing module is also used to periodically trigger the motor drive module through motor control signals;

[0121] The motor drive module is used to drive the motor to make the observed object perform the same periodic reciprocating motion in response to periodic triggering;

[0122] The ultrasound device under test is used to perform the steps of the above-described method for synchronous detection of medical ultrasound images and electrocardiogram signals.

[0123] In one optional embodiment of this application, such as Figure 4 As shown, the synchronous detection system for medical ultrasound images and electrocardiogram (ECG) signals may include the ultrasound device under test, an ECG simulator, an ECG signal processing module (ECG signal processing module), a motor drive module, a motor, and a water tank; the ultrasound probe of the ultrasound device under test is placed on the object being observed (the ultrasound probe does not contact the object being observed), ensuring that the acoustic window of the probe is completely submerged below the surface of the water in the tank.

[0124] The ultrasound device under test, the electrocardiogram simulator, the electrocardiogram signal processing module, the motor drive module, and the motor are electrically connected in sequence; the ultrasound device under test and the electrocardiogram signal processing module are connected to the electrocardiogram simulator through different lead signals.

[0125] An electrocardiogram (ECG) simulator is used to generate periodic ECG signals and send them to the ECG signal processing module.

[0126] The electrocardiogram (ECG) signal processing module is used to receive periodic ECG signals and convert them into motor control signals with the same periodicity as the periodic ECG signals.

[0127] The electrocardiogram signal processing module is also used to periodically trigger the motor drive module through motor control signals;

[0128] The motor drive module is used to respond to periodic triggering and drive the motor in the water tank to make the observed object perform the same periodic reciprocating motion in the water tank.

[0129] The ultrasound device under test is used to perform the steps of the above-described method for synchronous detection of medical ultrasound images and electrocardiogram signals.

[0130] The density difference between the density of the observed object's material and the density of water is greater than a preset density difference threshold. In an optional embodiment of this application, the density of the observed object's material can be greater than the density of water to prevent the observed object from being equal to or close to the density of water, thus preventing it from floating in the water.

[0131] In one embodiment of this application, the object of observation can be a spherical object. Exemplarily, the diameter of the spherical object meets a preset condition. For example, a spherical object with a smaller diameter can be selected as the object of observation. For instance, a spherical object with a diameter less than or equal to 10 millimeters can be selected as the object of observation. Optionally, a spherical object with a diameter greater than or equal to 2-3 millimeters and less than or equal to 10 millimeters can be used.

[0132] To facilitate understanding by those skilled in the art, ultrasound B-mode images are used as an example. Figure 5 A schematic diagram of an observed object image corresponding to an observed object undergoing periodic reciprocating motion in a water tank is provided. In the above embodiment, the observed object in the water tank can reciprocate horizontally. It is understood that the direction of motion of the observed object is not limited to the horizontal direction. For example... Figure 5 As shown, d1 is the distance of the reciprocating motion range, and d2 is the distance from the starting position of the object's relative motion at the detection time, i.e., the relative distance of the object's motion. Thus, the ratio of the object's motion distance can be expressed as d2 / d1.

[0133] Using ultrasound B-mode images as an example Figure 2 The provided diagram illustrates an electrocardiogram (ECG) signal waveform image, where the ECG data distance ratio can be expressed as m2 / m1. Thus, the synchronization performance quantification value can be expressed as |d2 / d1–m2 / m1| or |m2 / m1-d2 / d1|.

[0134] As an optional embodiment of this application, the synchronization performance quantification value can also be expressed as |d1 / d2–m1 / m2| or |m1 / m2-d1 / d2|. That is, the ratio of object movement distance can also be expressed as d1 / d2; the ratio of ECG data distance can also be expressed as m1 / m2.

[0135] In an optional embodiment of this application, after the ultrasound device under test simultaneously displays the image of the observed object in periodic motion and the waveform image of the electrocardiogram corresponding to the periodic electrocardiogram signal, the ultrasound device under test can respond to the screenshot request at the detection time and save the image of the observed object and the waveform image of the electrocardiogram at the detection time. Thus, the image of the observed object and the waveform image of the electrocardiogram at the detection time can be used to measure the reciprocating motion range distance and the electrocardiogram peak distance, as well as the electrocardiogram data movement distance and the relative distance of the object movement. Based on the measured reciprocating motion range distance, electrocardiogram peak distance, measured electrocardiogram data movement distance and the relative distance of the object movement, a synchronization performance quantification value can be obtained.

[0136] Understandably, when there are at least two detection times, the final quantified value of the synchronization performance of the ultrasound device under test (i.e., the target quantified value of the synchronization performance of the ultrasound device under test, which is used to quantify the synchronization performance between the ultrasound image and the electrocardiogram signal of the ultrasound device under test, and the correlation between the target quantified value and the synchronization performance is negative) can be determined based on the average, standard deviation or variance of the quantified value of the synchronization performance corresponding to each detection time.

[0137] In practical applications, the acceptance criteria (synchronization performance quantification threshold) for synchronization performance indicators can be set in conjunction with clinical settings. For example, without affecting the user's misjudgment, the acceptance criteria (synchronization performance quantification threshold) can be comprehensively defined by considering indicators such as the display size and resolution of the product images (ultrasound images and ECG waveform images). By comparing the synchronization performance quantification threshold with the final synchronization performance quantification value corresponding to the ultrasound device under test, it can be determined whether the ultrasound image of the ultrasound device under test is consistent with (synchronized) the physiological state expressed by the ECG signal.

[0138] Based on the same inventive concept, this application also provides a medical ultrasound image and electrocardiogram (ECG) signal synchronization detection device for implementing the above-described method for synchronous detection of medical ultrasound images and ECG signals. The device is applied to the ultrasound device under test; the ultrasound device under test is electrically connected to an ECG simulator; the periodic ECG signal generated by the ECG simulator is used to drive the observed object to perform reciprocating motion within the same period; the ultrasound device under test is used to detect the observed object.
