The medical workstation is a place where medical image examination is performed on a human body by using professional medical equipment and medical examination equipment is provided, and can be a medical institution or a department unit with medical examination equipment in the medical institution, such as an image center. The types of the medical examination instruments include but are not limited to ECG machines, X-ray machines, CT machines, MRI machines, ultrasonic machines and the like, more than two or all the medical examination instruments in the medical workstation can be selected to be simultaneously connected with the database system, and information is jointly acquired through a plurality of the medical examination instruments. The medical examination instrument carries out medical examination on a human body, collects medical image information of the human body and corresponding medical diagnosis and treatment information, and then transmits the collected information to the database system. The database system processes the collected medical image information and the corresponding medical diagnosis and treatment information, and a multi-mode information model is established by utilizing the artificial intelligence module to form a model database. The diagnosis and analysis system calls an existing model database to study and judge the clinically acquired medical image information, outputs a standardized medical diagnosis and treatment report through the information feedback system, simultaneously stores the data of the diagnosis and treatment in the database system, and updates the model database in the database system. The standardized medical diagnosis and treatment report can be unified in format and terms, and recorded information is more accurate and comprehensive. The report output by the information feedback system can be presented on a computer terminal or other terminals, and has the functions of doctor intervening in the diagnosis result and increasing database data, the diagnosis result needs the doctor to correct, and the correct diagnosis and treatment data is used as the source of machine learning and system application. The database system is the basis of the whole system and at least comprises a feature index table, a feature library, an experience image database and the like.
Depending on the instrument, the type of medical image information includes, but is not limited to, a three-dimensional image, a two-dimensional image, a sound, a motion state, a blood flow velocity and a blood flow rate, and the like, wherein the three-dimensional image and the two-dimensional image include information such as the shape, structure, color, and the like of an organ.

The multi-modal information model contains information including, but not limited to, a three-dimensional reconstruction model, visual information, and textual information.
The implementation process of the intelligent disease diagnosis and treatment system comprises a database building process and an application learning process. Taking cardiac diagnosis and treatment as an example, the database system utilizes an artificial intelligence module to establish a multi-modal information model by the following steps:
firstly, dynamic modal decomposition and fusion are carried out on a source image. The images acquired by the medical examination apparatus may include cardiac gray scale echocardiography, multi-slice echocardiography, and color doppler flow visualization, as well as other related different types of images. To perform multi-scale decomposition and reconstruction of images and to construct a fusion rule, in an image decomposition step, a GIF (Graphics Interchange Format) method is used to decompose a source image into smooth images, i.e., various scale images having the same resolution as an input image in a spatial domain. In the fusion rule construction step, a spatial residual importance detection algorithm spectrum residual method (SR) is used to construct a smooth image fusion rule that can distinguish important information from redundant information. And constructing a fusion rule of the detailed image by adopting an image-based visual saliency detection algorithm so as to generate a more compact and consistent fusion result and a visual system, and obtaining the fusion image by utilizing the fusion rule.
Second, labels and classifications are added to the echocardiograms collected for a large number of different slices. And adding labels to all the pictures according to the section types to serve as a section classification training data set. For example, the multi-section echocardiogram comprises different valves and chambers, and whether the valves and the chambers are normal or not is detected according to different section targets (see fig. 2). And manually or automatically adding a target detection frame and corresponding labels to the echocardiograms with different section types by using a data set label function, and constructing a training data set of a target detection algorithm. The ResNet neural network is adopted to automatically classify the stored pictures, the structure of the ResNet neural network can accelerate the training of the ultra-deep neural network very quickly, and the accuracy of the model is greatly improved.
In the image processing process, the classified echocardiograms are subjected to real-time target detection on each valve and chamber by adopting an end-to-end target detection neural network, so that medical diagnosis is realized. As an improvement, a target detection neural network and an exclusive-or network are combined to form a mixed precision neural network, and the target detection precision of the high-precision ultrasonic image and the operation efficiency of the neural network are balanced.
The dynamic image is then combined with the static image and its representation is identified. Taking the heart as an example, the motion of the target is observed clinically according to an echocardiogram, and the state of the heart is judged by combining other data. Such as acoustic quantification and dynamic color chamber walls, can reflect the index features of the heart, and optical flow and speckle tracking can reflect the motion state of the heart.
Then, the medical image is three-dimensionally reconstructed, a complete three-dimensional model is reconstructed by adopting an improved MC Algorithm (Marching Cubes Algorithm), and the model is stored or updated through subsequent processing. The improved MC algorithm is expanded from the original 15 topological configurations to 24 topological configurations, the problem of cavities on the surface of a model is solved, a midpoint selection method is adopted to replace a linear interpolation method, the calculated amount is simplified on the formula, the 24 topological configurations are divided into three types, each type corresponds to a macro, a processing function is called by a macro trigger function pointer, the opening and closing principle and the expansibility of the types are effectively maintained, the three types of configurations respectively correspond to three threads, the threads are synchronized in a critical zone mode, and the safety of a program is guaranteed.
Furthermore, the electrocardiogram waveform and the image data are synchronously processed and analyzed, and diversified data are recorded.
Then, images from different imaging devices, which are referred to as multi-modality images, are subjected to registration processing by multi-modality machine learning. For image registration, various index results can be obtained according to actual image characteristics and a registration algorithm. Therefore, the multi-modal information model formed by the invention can be flexibly changed according to the actual situation, and has very wide application modes.
And finally, carrying out structural division and feature point subdivision on different disease diagnosis and diagnosis branches by using a decision tree model. The decision tree is a process for carrying out tree classification on sample data from top to bottom, and comprises nodes and directed edges, node atmosphere internal nodes and leaf nodes, wherein each internal node represents a feature or a tree shape, and the leaf nodes represent categories. All samples are gathered together from the top root node and are divided into different sub-nodes, and all samples are classified into one leaf node through further division of the characteristics of the sub-nodes. The decision tree model is beneficial to improving the diagnosis and treatment accuracy and the diagnosis and treatment efficiency.
