A threaded rod is provided through the position where the support frame 10 is embedded in the connecting frame 12. The outer portion of the threaded rod is threadedly matched with the position where the support frame 10 passes through. Both ends of the threaded rod are respectively rotatably connected to the inside of the connecting frame 12. The position of the limiting roller 15 can be independently adjusted by rotating the threaded rod inside the connecting frame 12 to adapt to patients of different heights and patients of different leg lengths.

[0056] like Figure 2 and Figure 8 As shown, a first lying board 4 is transversely arranged at the lower end of the ultrasound box 2, and the lower end of the first lying board 4 is embedded in the shell 1 and slidably connected with the inside of the shell 1. A threaded rod is arranged through the position of the first lying board 4 embedded in the shell 1, and the rotation of the threaded rod can be matched with the threaded position of the first lying board 4. The rotation of the threaded rod can simultaneously drive the second lying board 5, the first lying board 4 and the third lying board 6 to move transversely together, so as to further adjust the position of the patient;

[0057] In order to facilitate the assistance of the patient sitting on the upper end of the first lying board 4, so that the patient can lie down stably, as shown in FIG. Figure 8 As shown, the third lying board 6 is arranged near the limiting roller 15 of the first lying board 4, and the second lying board 5 is arranged on the side of the first lying board 4 away from the third lying board 6. During the diagnosis process, the patient's upper body lies on the second lying board 5, the patient's lower body lies on the third lying board 6, and the patient's buttocks are supported by the first lying board 4;

[0062] Among them, the lower end of the first lying board 4 is rotatably connected to the roller 8 through the fourth connecting shaft 20. When the orientation of the first lying board 4 needs to be adjusted, the first lying board 4 directly drives the second lying board 5 and the third lying board 6 to rotate with the fourth connecting shaft 20 as the center. The lower end of the fourth connecting shaft 20 is provided with a motor fixedly connected to the roller 8, and the angle can be driven to be adjusted through the output of the motor output shaft.

[0063] To further understand the content of the present invention, please refer to Fig. 9 , this embodiment provides the following technical solutions:

[0064] The holographic imaging ultrasonic diagnostic device also includes a diagnostic system at the front end of the housing 1, the diagnostic system including: an ultrasonic transmitting module, an ultrasonic receiving module, a signal conversion module, a data processing module, an image reconstruction module, a display module, a power management module and a fault warning remote assistance module, wherein:

[0065] Ultrasonic emission module: responsible for generating ultrasonic signals of specific frequency and intensity. Ultrasonic signals can penetrate human tissues and generate reflected waves according to the acoustic characteristics of different tissues, providing the original data source for subsequent imaging. The frequency and pulse width parameters of ultrasonic waves can be adjusted to meet the detection needs of different depths and types of tissues. Higher-frequency ultrasonic waves can provide higher resolution in shallow tissue imaging, while lower-frequency ultrasonic waves can better penetrate deep tissues. It is directly connected to the core ultrasonic function of the device and can accurately control the emission parameters of ultrasonic waves, reduce the loss and interference during signal transmission, and ensure the quality of the emitted ultrasonic signals. As a built-in module, it can work better with other parts of the device, such as the power management module, to adjust the power parameters of ultrasonic emission according to the overall working status and improve the energy efficiency of the equipment.

[0066] Ultrasonic receiving module: Receives ultrasonic signals reflected from human tissue. The reflected waves carry the structure and characteristics of human tissue. The received weak ultrasonic signals are amplified and filtered to improve the signal quality so that the subsequent processing module can accurately analyze the information in the signal. It is placed close to the transmitting module to receive the reflected waves more effectively and reduce the interference of external noise. The attenuation of the reflected waves during transmission is minimized, which helps to improve the integrity of the signal. It can easily share the power supply and grounding lines with other electronic components in the device, simplify the circuit design, and reduce the equipment cost.

[0067] Signal conversion module: converts the received ultrasonic signal into a digital signal, samples the digital signal at a certain sampling frequency through an analog-to-digital converter, and quantifies the digital signal into a digital value for processing by the computer system. It preliminarily encodes the converted digital signal to meet the input requirements of the subsequent processing module and is integrated with other modules to reduce external connection lines, reduce the risk of electromagnetic interference during signal transmission, and improve the anti-interference ability of the entire system;

[0068] Data processing module: processes the converted digital signals, performs beamforming and focusing on the digital signals to improve the resolution and clarity of the image, synthesizes and analyzes the digital signals collected at different angles and positions, and constructs three-dimensional holographic image data. It can directly obtain the data generated by other modules inside the device without the need for transmission through complex external interfaces, thus improving the speed and security of data transmission and quickly generating high-quality holographic images;

[0069] Image reconstruction module: converts the holographic image data obtained by the data processing module into a visual image, converts the digital signal into an ultrasound image that can be intuitively understood by the doctor, into a tomographic image or a three-dimensional image, and adjusts the contrast and brightness parameters to improve the visibility of the image so that the image can be displayed with the best effect on the display screen of the device;

[0070] Display module: responsible for displaying the ultrasound image generated by the image reconstruction module, so that doctors can observe the image from different angles and make accurate diagnoses. It is directly connected to the image reconstruction module, can quickly display the image, and reduce the delay and image quality loss during signal transmission;

[0071] Power management module: provides a stable power supply for the entire detection system, converts the external input power into different voltages and currents required by each module, provides high-voltage pulse power for the ultrasonic transmitter module, and provides low-voltage DC power for other electronic modules to ensure the safe operation of the device. According to the actual power consumption requirements of each module, it reasonably allocates power resources, improves the utilization efficiency of the power supply, and prolongs the battery life of the device;

[0072] Self-check and calibration module: When the holographic imaging ultrasonic diagnostic device is started and operated regularly, each module is self-checked to check whether the function of each module is normal, and each module is calibrated according to the self-check results. If a deviation is found in the ultrasonic emission frequency, the ultrasonic emission module is calibrated to ensure the accuracy of the device. It can deeply detect the status of each module inside the device. Since it is a built-in module, the internal parameters of each module can be directly obtained to perform more accurate self-check and calibration operations. After the problem is found, it can be quickly adjusted and repaired, reducing the device failure time and improving the availability of the equipment.

[0073] Working principle: When using the holographic imaging ultrasound diagnostic device to diagnose a patient who is unable to move in a wheelchair, the patient is pushed between the third lying board 6 and the limiting roller 15 and toward the limiting roller 15. The limiting frame 11 rotates counterclockwise to approach the patient's ankle, and the patient's foot is placed between a pair of limiting rollers 15. The limiting frame 11 rotates clockwise to lift the patient's foot and leg. The extension of the tray 13 pushes the tray 13 to move to the lower end of the lifted leg. The threaded rod running through the inside of the support frame 10 is started and moves laterally under the restriction of the transmission frame 9, so that the tray 13 and the limiting roller 15 move toward the patient at the same time. The pair of limiting rollers 15 will slide on the patient's legs, and the tray 13 will be embedded between the patient's buttocks and the wheelchair cushion. The limiting frame 11 rotates counterclockwise again to the patient's ankle position. The rotation of the threaded rod inside the transmission frame 9 is restricted by the shell 1, so that The tray 13 and the patient on the upper end of the tray 13 are separated from the wheelchair and move vertically upward. The threaded rod running through the inside of the support frame 10 is started again to push the tray 13 toward the upper end of the first reclining board 4. The patient or medical staff assists in pressing the patient so that the patient is close to the second reclining board 5. The limiting frame 11 rotates clockwise again to lift the patient's feet and legs. The tray 13 is pulled out to the lower end of the patient's buttocks after being driven by the threaded rod. At the same time, the lateral movement will also cause the patient's ankle position to fall off from between a pair of limiting rollers 15. Finally, after the third reclining board 6 and the second reclining board 5 are output through the motor respectively, the third reclining board 6 and the second reclining board 5 respectively rotate with the third connecting shaft 19 and the second connecting shaft 18 as the center of the circle and allow the patient to lie flat on the second reclining board 5, the first reclining board 4 and the upper end of the third reclining board 6. Finally, the ultrasonic box 2 emits an ultrasonic signal to detect and diagnose the patient.

[0074] Based on the above embodiment, the diagnostic system further includes:

[0075] Image recognition model building module: Based on deep learning technology, a convolutional neural network (CNN) is built to automatically analyze and identify ultrasound images;

[0076] Feature extraction module: It uses multiple convolutional layers of convolutional neural network (CNN) to automatically extract image features. Each convolutional layer contains multiple convolution kernels to capture features at different levels.

[0077] Classification and recognition module: The extracted features are input into the fully connected layer of the convolutional neural network (CNN) for classification and recognition. The fully connected layer maps the features to different categories.

[0078] Model feedback learning module: compares the recognition results of the classification recognition module with the doctor's diagnosis results, adjusts the weights of the convolutional neural network through the error back propagation algorithm, and implements model performance optimization. The error back propagation algorithm is as follows:

[0079]

[0080] Among them, ΔW is the update amount of the weight, η is the learning rate, represents the gradient of the weight, L(C,Y) is the loss function, C is the model parameter, and Y is the true label.

[0081] Specifically, a convolutional neural network (CNN) is used as the basis to construct an image recognition model, automatically extract image features, and perform classification and recognition. According to the doctor's diagnosis results, the weights of the convolutional neural network are adjusted through the error back propagation algorithm to implement performance optimization of the image recognition model. This solution aims to continuously improve the recognition accuracy of human tissues and lesions in ultrasound images; enable the equipment to automatically identify and distinguish different human tissues, such as muscle, fat, and bone, and train the model through deep learning technology to improve the recognition accuracy of tissue boundaries in ultrasound images; this solution can analyze ultrasound images in real time, identify abnormal structures, such as tumors, cysts or other lesions, and mark them, assisting doctors to quickly locate problem areas and assist doctors in diagnosing diseases.

[0082] Based on the above embodiment, the self-checking and calibration module includes:

[0083] Ultrasonic emission self-test submodule: By detecting the ultrasonic signal emitted by the ultrasonic emission module, the emitted ultrasonic signal is compared with the expected parameters to check whether the frequency and intensity of the ultrasonic signal meet the requirements;

[0084] Ultrasonic receiving self-test submodule: detects whether the ultrasonic receiving module can effectively receive the reflected ultrasonic signal, and performs quality assessment on the received ultrasonic signal. The quality assessment items include whether the signal strength and noise level meet the requirements;

[0085] Image reconstruction self-check submodule: Verify whether the image reconstruction module can convert holographic image data into clear ultrasound images, and check whether the image reconstruction meets the requirements by evaluating the clarity and accuracy of the reconstructed ultrasound images;

[0086] Automatic calibration submodule: For functional modules whose self-test results do not meet the requirements, automatic calibration is performed using the corresponding set calibration method, and a prompt for automatic calibration is issued. The last ultrasound diagnosis before automatic calibration is re-diagnosed.

[0087] Specifically, by automatically detecting the ultrasonic transmitting module, the ultrasonic receiving module and the image reconstruction module, it is evaluated whether the functional modules meet the corresponding parameter requirements. For the functional modules whose self-test results do not meet the requirements, automatic calibration is performed accordingly through the set calibration method, and a prompt for automatic calibration is issued. After the automatic calibration is completed, the diagnostic examination is re-performed for the last ultrasonic diagnosis before the automatic calibration. This solution can ensure that the diagnostic device (equipment) is always in good condition so that it can be used for patient diagnosis at any time, and the reliability of each ultrasonic diagnostic result is guaranteed.
