Image Management Device Server Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image management devices experience long image display times due to the need to transmit medical images to a server with a lower load, which can result in prolonged processing and transmission times, especially in varying communication environments.
Innovation Solution
An image management device that identifies the storage device storing the image data based on associated identification information and instructs it to perform image processing, then receives and transmits the processed data to the client terminal, minimizing data transfer between servers and reducing display time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the medical image is transmitted to a server with lower load for processing, then the load distribution is improved, but the transmission time and display time are increased
Solution Approach 1:
The patent applies preliminary action by having the storage server perform image processing on medical images before they are requested by client terminals. The processed images are pre-generated and stored, so when a client requests an image, the processed version is already available for immediate transmission, eliminating the need to wait for processing after the request is made.
Solution Approach 2:
The patent introduces the storage server as an intermediary that performs image processing locally without requiring transmission to a separate processing server. The storage server acts as both the storage location and the processing unit, eliminating the need for images to be transmitted to another server for processing and then transmitted back to the client.
2Productivity
If the medical image is transmitted to a remote server for processing, then the processing capability is improved, but the communication time is increased
Solution Approach 1:
The patent applies local quality by enabling the storage server to perform image processing locally at the location where images are stored. This eliminates the need to transmit images over the network to remote processing servers, thereby reducing communication time while maintaining processing capability.
3Device complexity
If the image processing is centralized on the main server, then the control is simplified, but the load on the main server is increased
Solution Approach 1:
The patent applies segmentation by dividing the system into multiple independent processing units (storage servers) that can handle image processing autonomously. Each storage server can process images locally, distributing the processing load across multiple nodes rather than concentrating it on a single main server, thereby reducing the load on any individual server while maintaining system functionality.

AI summary
An image management device that is communicably connected to a client terminal and a plurality of image storage devices, includes: a storage that stores identification information of image data with the identification information associated with an image storage device in which the image data is stored; a hardware processor that identifies an image storage device that stores image data specified by an image-data transmission request received from the client terminal based on the identification information of the image data stored in the storage, and instructs the identified image storage device to subject the image data specified by the transmission request to image processing; and a communicator that receives, from the identified image storage device, processed image data that has been subjected to the image processing, and transmits the processed image data to the client terminal.
