Description

Technical Field

[0001] The present invention relates to the technical field of intelligent monitoring systems, and in particular to an intelligent monitoring system used in the uterus. Background Art

[0002] In the prior art, the uterine intelligent monitoring system is an advanced medical device designed to monitor the health of the uterus in real time and provide an important reference for clinical diagnosis and treatment. The system usually includes multiple sensors, a data processing unit and a user interface, which can continuously monitor multiple physiological parameters of the uterus. In the uterine intelligent monitoring system, sensors are one of the key components. These sensors can be pressure sensors, temperature sensors, electrophysiological sensors, etc., which are used to detect parameters such as pressure, temperature, and electrical activity inside the uterus. The sensor converts these physiological signals into electrical signals and then sends them to the data processing unit through a data transmission interface. The data processing unit is the core part of the uterine intelligent monitoring system, which is responsible for receiving data from the sensor and performing real-time analysis and processing. The unit usually includes an analog to digital converter (ADC), a microprocessor, a memory, and various algorithms. Through advanced signal processing technology, the data processing unit can extract useful information such as the frequency, intensity, and duration of uterine contractions. The user interface is a bridge for the interaction between the uterine intelligent monitoring system and the user, and usually includes a display screen, control buttons, and an alarm device. Through the user interface, the monitoring data can be viewed in real time to understand the health of the uterus. In addition, the user interface can also set an alarm threshold. Once the monitoring data exceeds the normal range, the system will automatically issue an alarm to remind you to take corresponding measures.

[0003] Chinese Patent Publication No.: CN110545712B discloses an intrauterine monitoring system, comprising an implantable sensor device, whose shape and size are suitable for implantation in the uterus, for measuring the conditions in the uterus to generate sensor data; and a wearable receiver device, which is used to wirelessly receive the sensor data generated by the implantable sensor device; wherein the wearable receiver device is operable to wirelessly charge the implantable sensor device; the wearable receiver device provides power to the implantable sensor device in multiple charging periods in a single operating cycle; wherein the multiple charging periods include: a first charging period, for providing power to the implantable sensor device to support the operation of the sensor in acquiring sensor data; a second charging period, for providing power to the implantable sensor device to support the transmission of the acquired sensor data to the wearable receiver device; and a third charging period, which is performed before the first charging period, for providing power to the implantable sensor device to support the startup process. It can be seen that the intrauterine monitoring system has problems such as reduced image accuracy due to interference with the signal sending unit and image loss due to tiny air bubbles encountered during signal transmission. Summary of the invention

[0004] To this end, the present invention provides an intelligent monitoring system for use in the uterus to overcome the problems in the prior art of reduced image accuracy due to interference with a signal sending unit and image loss due to tiny air bubbles encountered during signal transmission.

[0005] To achieve the above object, the present invention provides an intelligent monitoring system for use in the uterus, comprising:

[0006] An information acquisition module, which acquires ultrasonic information of the uterus by ultrasonic detection of the uterus, and includes a signal sending unit for sending ultrasonic signals to the uterus and a signal receiving unit for receiving echo signals of the uterus;

[0007] a signal processing module connected to the information acquisition module and used to generate a uterine ultrasound image according to the echo signal, comprising an image generation unit connected to the signal receiving unit and used to generate the uterine ultrasound image according to the echo signal, and an error image recognition unit connected to the image generation unit and used to recognize an error image according to an autocorrelation value of the echo signal in a time series, wherein the uterine ultrasound image is composed of a plurality of frames of the uterine ultrasound image;

[0008] A database, connected to the signal processing module, for storing several types of the error images and the uterine ultrasound images respectively;

[0009] An image processing module, which is respectively connected to the signal processing module and the database, and is used to optimize the uterine ultrasound image, including an image recovery unit connected to the error image recognition unit to restore the loss area of ​​the error image according to the similarity between the loss area and the circle, and an image optimization unit connected to the error image recognition unit to compare and optimize the problem image.

[0010] Furthermore, the error image recognition unit is also used to determine the continuity of the echo signal according to the autocorrelation value of the echo signal intensity in the time series;

[0011] If the autocorrelation value is less than or equal to a preset threshold, it is determined that the continuity of the echo signal does not meet the requirement.

[0012] Furthermore, the database includes:

[0013] a signal storage unit, connected to the signal receiving unit, for storing the echo signal;

[0014] An image storage unit, connected to the image generation unit, for storing a plurality of frames of the uterine ultrasound images, the problem images, and uterine ultrasound images with missing images;

[0015] The echo signal and several frames of uterine ultrasound images are stored correspondingly in the same time interval.

[0016] Furthermore, the image restoration unit is connected to the error image recognition unit to obtain the loss area of ​​the problem image when the continuity of the echo signal does not meet the requirement, and calculate the similarity between the loss area in the problem image and the circle.

[0017] If the similarity is greater than a preset similarity threshold, it is determined that the accuracy of the echo signal does not meet the requirement, wherein the problematic image includes an image with signal loss and an image with artifacts.

[0018] Furthermore, the image recovery unit is connected to the image storage unit, and is used to obtain several block images adjacent to the loss area in the problem image when the accuracy of the echo signal does not meet the requirements, superimpose the image feature information of the several block images onto the loss area of ​​the problem image to perform superimposition recovery on the loss area, and mark and update the superimposed and recovered problem image in the uterine ultrasound image.

[0019] Furthermore, the image optimization unit is connected to the error image recognition unit and the image storage unit respectively, so as to obtain the problem image when the continuity of the echo signal meets the requirements and the accuracy of the echo signal meets the requirements, and compare and optimize the historical image in the image storage unit with the problem image.

[0020] Furthermore, the problem image is optimized by using image registration technology to align the length and width of the problem image with the historical image to compare the same type of features one by one, so as to screen out feature points in the comparison features whose feature values ​​do not meet the feature value standard range;

[0021] If the ratio of the number of the feature points to the total number of feature points in the problem image exceeds a preset ratio, the feature values ​​of the feature points in the problem image exceeding the preset ratio are replaced with feature values ​​under the same conditions in the historical image.

[0022] Furthermore, the error image recognition unit is respectively connected to the signal storage unit and the image storage unit to obtain the missing image information and the echo signal corresponding to the missing image information, and the missing image is reconstructed by sending the echo signal corresponding to the missing image information to the image generation unit.

[0023] Furthermore, the image processing module is also used to perform real-time marking and updating on the optimized uterine ultrasound image and the reconstructed uterine ultrasound image in the uterine ultrasound image.

[0024] Furthermore, the image optimization unit is also used to compare the uterine ultrasound image after the mark is updated with the historical uterine ultrasound image of the same monitoring position to output the real-time status of the uterus.

[0025] Compared with the prior art, the beneficial effect of the present invention lies in that the system of the present invention determines the cause of the delay in the uterine ultrasound image by determining the continuity of the echo signal through setting an information acquisition module, a signal processing module, a database and an image processing module, restores the damaged image when the continuity of the echo signal does not meet the requirements, and optimizes the problem image when the continuity of the echo signal meets the requirements, thereby improving the image quality and further improving the image accuracy; since image information is missing due to factors such as the patient's position, the angle of the signal transmitter and the performance of the imaging device during the imaging process, the missing image information is reconstructed through the echo signal, which can reduce repeated inspections caused by image quality problems, and the signal processed by the reconstruction algorithm can improve the information content and accuracy of the reconstructed image, thereby improving the integrity and accuracy of the image and enhancing the image clarity.

[0026] Furthermore, the system of the present invention determines the continuity of the echo signal by setting a preset threshold. Since the real-time performance of the image is reduced due to the delay caused by electromagnetic interference encountered in the process of signal transmission and image generation during the actual uterine ultrasound image presentation, the influencing factors of the delay are determined to determine different adjustment methods, thereby increasing the real-time performance of obtaining image information and improving the accuracy of uterine ultrasound image results.

[0027] Furthermore, the system of the present invention improves data traceability by setting up a signal storage unit and an image storage unit, by directly saving the original echo signal and the processed image, while facilitating the tracking and comparative analysis of the disease, reducing the occurrence of data loss or damage, and further improving the integrity of the echo signal and the image.

[0028] Furthermore, the system of the present invention determines the accuracy of the echo signal by setting a preset similarity threshold, and then determines the influencing factors of the echo signal. Since the patient's posture or bubbles in the gel on the patient's body surface cause loss to the image in the process of receiving the echo signal, the loss area is restored by superimposing the image near the loss area, thereby reducing the risk of erroneous judgment results due to image missing, and screening the influence of bubble artifacts on the accuracy of image output results, thereby further improving image accuracy.

[0029] Furthermore, the system of the present invention compares and optimizes the problem image. Since the problem image may have poor clarity and unclear graphic edges due to the echo signal encountering a strong reflection interface in the body or being affected by external electromagnetic interference during the echo signal conversion process, the problem image is compared and optimized with the historical image to achieve clear image features, thereby further improving image quality and image accuracy.

[0030] Furthermore, the system of the present invention reconstructs missing image information. Since the image is missing due to the long working time in the process of echo signal conversion, the image is reconstructed by using the echo signal, thereby compensating for the continuity of the uterine ultrasound image presentation. The image reconstructed by the echo signal is clearer, further achieving the improvement of image quality.

[0031] Furthermore, the system of the present invention is arranged to enhance the accuracy of abnormal manifestations in the verification image by comparing with similar images, and to speed up the system working efficiency by updating and analyzing the uterine ultrasound image, thereby realizing a feedback loop between the uterine ultrasound image and historical similar uterine ultrasound images, thereby achieving the improvement of the speed and accuracy of image processing.

[0040] See also Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, they are respectively an overall structural block diagram, a database structural block diagram, an image processing module structural block diagram and a logic flow chart of an intelligent monitoring system for the uterus according to an embodiment of the present invention. An intelligent monitoring system for the uterus according to the present invention comprises:

[0041] An information acquisition module, which acquires ultrasonic information of the uterus by ultrasonic detection of the uterus, and includes a signal sending unit for sending ultrasonic signals to the uterus and a signal receiving unit for receiving echo signals of the uterus;

[0042] a signal processing module connected to the information acquisition module and used to generate a uterine ultrasound image according to the echo signal, comprising an image generation unit connected to the signal receiving unit and used to generate the uterine ultrasound image according to the echo signal, and an error image recognition unit connected to the image generation unit and used to recognize an error image according to an autocorrelation value of the echo signal in a time series, wherein the uterine ultrasound image is composed of a plurality of frames of the uterine ultrasound image;

[0043] A database, connected to the signal processing module, for storing several types of the error images and the uterine ultrasound images respectively;

[0044] An image processing module, which is respectively connected to the signal processing module and the database, and is used to optimize the uterine ultrasound image, including an image recovery unit connected to the error image recognition unit to restore the loss area of ​​the error image according to the similarity between the loss area and the circle, and an image optimization unit connected to the error image recognition unit to compare and optimize the problem image.

[0045] Specifically, the ultrasonic information of the uterus includes an echo signal of the uterus and a reception time of the echo signal.

[0046] Specifically, the signal sending unit is an ultrasonic transmitter, and the signal receiving unit is an ultrasonic receiver.

[0047] Specifically, the echo signal is a B-ultrasound signal.

[0048] In implementation, the system of the present invention sets an information acquisition module, a signal processing module, an image recovery module and an image processing module, determines the cause of the delay in the uterine ultrasound image by determining the continuity of the echo signal, restores the damaged image when the continuity of the echo signal does not meet the requirements, and optimizes the problem image when the continuity of the echo signal meets the requirements, thereby improving the image quality and further improving the image accuracy; since image information is missing due to factors such as the patient's position, the angle of the signal transmitter and the performance of the imaging device during the imaging process, the missing image information is reconstructed through the echo signal, which can reduce repeated inspections caused by image quality problems, and the signal processed by the reconstruction algorithm can improve the information content and accuracy of the reconstructed image, thereby improving the integrity and accuracy of the image and enhancing the image clarity.

[0049] Specifically, the error image recognition unit is also used to determine the continuity of the echo signal according to the autocorrelation value of the echo signal intensity in the time series;

[0050] If the autocorrelation value is less than or equal to a preset threshold, it is determined that the continuity of the echo signal does not meet the requirement.

[0051] Specifically, the autocorrelation value of the echo signal intensity in the time series is the similarity of the time delay between the echo signal at a single moment and a single moment.

[0052] Specifically, autocorrelation is the cross-correlation of a signal with itself at different time points, and is also a function of the similarity between two observations versus the time difference between them. It is a mathematical tool for finding repetitive patterns (such as periodic signals masked by noise) or identifying the fundamental frequency that disappears in the harmonic frequency of the signal. The method for calculating the autocorrelation value is a conventional technical means well known to those skilled in the art, so the calculation process of the autocorrelation value will not be repeated here.

[0053] In implementation, the preset threshold value generally ranges from [0.6, 0.7].

[0054] Preferably, the preset threshold is 0.68.

[0055] In implementation, the system of the present invention determines the continuity of the echo signal by setting a preset threshold. Since the delay caused by electromagnetic interference in the process of signal transmission and actual uterine ultrasound image presentation causes the signal to generate an image, the real-time performance of the image is reduced. By determining the influencing factors of the delay and thus determining different adjustment methods, the real-time performance of obtaining image information and the accuracy of uterine ultrasound image results are increased.

[0056] Specifically, the database includes:

[0057] a signal storage unit, connected to the signal receiving unit, for storing the echo signal;

[0058] An image storage unit, connected to the image generation unit, for storing a plurality of frames of the uterine ultrasound images, the problem images, and uterine ultrasound images with missing images;

[0059] The echo signal and several frames of uterine ultrasound images are stored correspondingly in the same time interval.

[0060] In implementation, the system of the present invention improves data traceability by setting up a signal storage unit and an image storage unit, by directly saving the original echo signal and the processed image, while facilitating the tracking and comparative analysis of the disease, reducing the occurrence of data loss or damage, and further improving the integrity of the echo signal and the image.

[0061] Specifically, the image restoration unit is connected to the error image recognition unit to obtain the loss area of ​​the problem image when the continuity of the echo signal does not meet the requirements, and calculate the similarity between the loss area in the problem image and the circle.

[0062] If the similarity is greater than a preset similarity threshold, it is determined that the accuracy of the echo signal does not meet the requirement, wherein the problematic image includes an image with signal loss and an image with artifacts.

[0063] Specifically, the loss area in an image with signal loss includes a shadow area and a ghost area, and the loss area in an image with artifacts is an artifact area.

[0064] Specifically, the loss regions in the problem image are identified through color contrast and edge detection.

[0065] Specifically, the process of calculating the similarity between the loss area in the problem image and the circle is to calculate the similarity between the circle in the image and the ideal circle through the structural similarity index.

[0066] In implementation, the general value range of the preset similarity threshold is [0.54, 0.58].

[0067] Preferably, the preferred embodiment of the preset similarity threshold is 0.56.

[0068] In implementation, the similarity between the loss area in the problem image and the circle exceeds a preset similarity threshold and is closer to 1, which means that the echo signal is more affected by the bubbles in the B-ultrasound detection gel and the accuracy of the echo signal is lower.

[0069] Specifically, the image recovery unit is connected to the image storage unit, and is used to obtain several block images adjacent to the loss area in the problem image when the accuracy of the echo signal does not meet the requirements, and superimpose the image feature information of the several block images onto the loss area of ​​the problem image to perform superimposition recovery on the loss area, and mark and update the superimposed and recovered problem image in the uterine ultrasound image.

[0070] Specifically, the method of overlaying and restoring the problem image is: using edge detection technology to identify the adjacent area of ​​the loss area in the problem image, dividing the adjacent area into several block images; extracting feature information from the several block images; and overlaying the feature information on the loss area.

[0071] Specifically, feature information includes color, texture, and edge information.

[0072] Specifically, superposition methods include pixel-based interpolation, texture synthesis, and image restoration algorithms such as Inpainting technology.

[0073] In implementation, the system of the present invention determines the accuracy of the echo signal by setting a preset similarity threshold, and then determines the influencing factors of the echo signal. Since the bubbles in the gel on the patient's body surface cause loss to the image during the process of receiving the echo signal, the loss area is restored by superimposing the image near the loss area, thereby reducing the risk of erroneous judgment results due to image loss, and screening the influence of bubble artifacts on the accuracy of image output results, thereby further improving the accuracy of uterine image monitoring.

[0074] Specifically, the image optimization unit is connected to the error image recognition unit and the image storage unit respectively, so as to obtain the problem image when the continuity of the echo signal meets the requirements and the accuracy of the echo signal meets the requirements, and compare and optimize the historical image in the image storage unit with the problem image.

[0075] Specifically, the method of performing comparison optimization on the problem image is to use image registration technology to align the length and width of the problem image with the historical image to compare the same type of features one by one, so as to screen out feature points in the comparison features whose feature values ​​do not meet the feature value standard range;

[0076] If the ratio of the number of the feature points to the total number of feature points in the problem image exceeds a preset ratio, the feature values ​​of the feature points in the problem image exceeding the preset ratio are replaced with feature values ​​under the same conditions in the historical image.

[0077] Specifically, contrast features include image edges, textures, and blood flow colors.

[0078] Specifically, the problem image is optimized by enhancing the contrast of key features and highlighting abnormal features.

[0079] During implementation, the system of the present invention compares and optimizes the problem image. Since the problem image may have poor clarity and unclear graphic edges due to the strong reflection interface encountered by the echo signal in the body or external electromagnetic interference during the echo signal conversion process, the clear image features are achieved by comparing and optimizing the historical image with the problem image, thereby further improving the image quality and image accuracy.

[0080] Specifically, the error image recognition unit is respectively connected to the signal storage unit and the image storage unit to obtain the missing image information and the echo signal corresponding to the missing image information, and the missing image is reconstructed by sending the echo signal corresponding to the missing image information to the image generation unit.

[0081] Specifically, the missing image information includes the echo signal corresponding to the missing part and the time corresponding to the missing image in the uterine ultrasound image.

[0082] Specifically, the image processing module is also used to perform real-time marking updates on the optimized uterine ultrasound image and the reconstructed uterine ultrasound image in the uterine ultrasound image.

[0083] During implementation, the system of the present invention reconstructs missing image information. Since the image is missing due to the long working time during the echo signal conversion process, the image is reconstructed by using the echo signal, thereby compensating for the continuity of the uterine ultrasound image presentation. The image reconstructed by the echo signal is clearer, further achieving improved image quality.

[0084] Specifically, the image optimization unit is further used to compare the uterine ultrasound image after the mark is updated with the historical uterine ultrasound image of the same monitoring position to output the real-time status of the uterus.

[0085] Specifically, the real-time status of the uterus includes the morphology of the uterus, the echo intensity inside the uterus, and the identification of new or disappeared lesions in the uterus.

[0086] In implementation, the system of the present invention is arranged to enhance the accuracy of abnormal manifestations in the verification image by comparing with similar images, and to speed up the system working efficiency by updating and analyzing the uterine ultrasound image, realizing a feedback loop between the uterine ultrasound image and historical similar uterine ultrasound images, thereby achieving the improvement of the speed and accuracy of image processing.

[0087] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
