Medical Image Data Transfer Latency Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transfer methods, such as TCP, often prioritize high bandwidth over low latency, leading to increased network congestion and delayed responses in applications that require real-time data streaming, such as medical image viewing systems.
Innovation Solution
A client-server based medical image viewing system uses timestamp messages to monitor network latency and adjust send bandwidth dynamically, ensuring high data throughput without compromising responsiveness. This system employs a feedback scheme to limit send bandwidth when latency increases, thereby preventing network congestion.

Engineering Contradiction Analysis
1Productivity
If TCP protocol is used to maximize data throughput, then bandwidth efficiency is improved, but network latency increases
Solution Approach 1:
The patent segments the data transfer process into multiple concurrent streams with different priority levels. High-priority data (such as user interactions in medical imaging) is transmitted separately from bulk data transfers, allowing critical data to bypass congestion and reduce latency while maintaining high overall throughput through parallel transmission channels.
Solution Approach 2:
The system dynamically adjusts transmission parameters based on real-time network conditions and data priority. It implements adaptive bandwidth allocation that can shift resources between different data streams, enabling the system to optimize for low latency when user interaction is detected while maintaining high throughput during bulk data transfers when the network is idle.
2Productivity
If large packets are sent to increase bandwidth utilization, then data throughput is improved, but response time deteriorates
Solution Approach 1:
The patent divides data into multiple packet sizes and priority levels rather than sending uniform large packets. Small high-priority packets are sent immediately for user interactions, while large packets are used for bulk data transfers during idle periods, eliminating the need to choose between packet size and response time.
Solution Approach 2:
The system implements periodic transmission cycles where bulk data transfers are paused or reduced when user interaction is detected, allowing small response-critical packets to be sent immediately. This periodic adjustment of transmission patterns ensures both high bandwidth utilization during idle periods and fast response times during interaction periods.

AI summary
Most of the internet traffic today is carried out via the Transmission Control Protocol (TCP). The main advantage of TCP is that it provides reliable data transfer to the application layer and simplifies programming. The protocol maximizes data throughput but may also lead to noticeable transmission delay in wide area networks (WAN). A client-server based medical image viewing system is disclosed that achieves high data throughput over TCP without impacting responsiveness. Special timestamp messages inserted into the data stream allow the system to detect situations where network latency increases noticeably and to obtain a reliable estimate of sustained transfer bandwidth. The system applies a feedback scheme that avoids network delays by limiting send bandwidth. In addition other parameters, in particular image compression settings, are dynamically adjusted depending on current network quality.
