Logic process for developing scalable online medical image analysis applications in Java

In the field of modern medicine, image analysis applications are increasingly in demand. With the popularity of electronic medical record systems, large amounts of medical image data are digitized and stored in databases. In order to effectively manage and analyze these data, it is important to develop a scalable online medical image analysis application. This article will introduce the logical process of an online medical image analysis application developed based on Java technology.

1. Requirements Analysis

Before developing an application, a requirements analysis is required to determine the functions and services that the application needs to provide. In this case, we need to develop an online medical image analysis application whose main functions include:

• Upload, store and manage multiple types of medical image data, including MRI, CT scans, X-ray images, etc.;
• Preprocess uploaded medical images, such as noise removal, contrast adjustment, etc.;
• Provides a variety of image analysis algorithms and technologies, including image segmentation, feature extraction, Object detection, classification, etc.;
• Present analysis results to users in a visual way;
• Implement functions such as multi-user access and permission management.

2. System architecture design

Based on the above demand analysis, we can design a multi-layer architecture application, including the following layers:

• User interface layer: Provides user management, image upload, image analysis, result display and other functions;
• Application server layer: Responsible for receiving, parsing and processing requests, calling corresponding business logic components, and Return response results;
• Business logic component layer: implement various analysis algorithms and technologies, such as image preprocessing, segmentation, feature extraction, object detection, classification, etc.;
• Data access layer: responsible Database for accessing and managing image data.

3. Implementation details

3.1 Image upload and database management

For image upload and database management, we can use the Java Web framework to implement . For example, the Spring framework is used to build the application server layer, and the Hibernate framework is used to implement the data access layer. By defining corresponding Java classes and annotations, the storage and query of medical image data can be easily managed.

3.2 Image preprocessing and analysis algorithm

For image preprocessing and analysis algorithms, we can use the Java image processing library to implement it. For example, use the OpenCV library to implement preprocessing operations such as image denoising, contrast adjustment, and histogram equalization. For analysis algorithms such as image segmentation, feature extraction, object detection and classification, deep learning frameworks such as TensorFlow or Keras can be used.

3.3 Result Display

For result display, we can use Java Web framework and JavaScript library to achieve it. For example, use the Spring MVC framework to implement the controller layer, and use JavaScript libraries such as D3.js, Plotly.js, etc. to implement visual icons and data display.

4. Summary

This article introduces the logical process of an online medical image analysis application developed based on Java technology. Through requirements analysis, system architecture design and implementation details, we can learn how to use Java technology and existing open source libraries to implement a scalable and powerful online medical image analysis application.
