Caching technology based medical image database searching method and searching system

Abstract

Aiming at the problems in the prior art that when searching image data in a PACS system having a plurality of data, especially searching simultaneously in a plurality of image workstation, workload of a database server is sharply raised, system speed is declined, and the overall cost is added, the invention provides a caching technology based medical image database searching method, which comprises: after receiving an initial searching request, searching firstly in a local caching list; sending final searching request to the database server if not searching it, transmitting it to a local image workstation if the database server searches it, reporting the searching result to the local image workstation if not searching it in the database server. By using the method, the image data searching speed is quickened, the workload of the database server is lightened, and the working efficiency of the PACS system is improved. The invention also provides a a caching technology based medical image database searching system, which is used for guaranteeing implementation and application of the method in actual system.

Description

technical field [0001] The invention belongs to the field of database retrieval, in particular to a medical image database retrieval method and retrieval system. Background technique [0002] In the process of diagnosis and treatment of diseases, hospitals and other health institutions have made extensive use of digital devices such as computers and emerging technologies such as network transmission and online storage. With the widespread use of these devices, a large number of digital medical imaging materials have been generated, such as patient fluoroscopy light films, detection videos of internal body structures, and video recordings of surgical procedures. All these image data are important intangible assets of medical institutions and can be used for case retrieval, teaching playback, experience exchange, etc. In order to facilitate the management, maintenance and use of these image data by medical units, usually, these image data are managed and organized in the form...

AI Technical Summary

Problems solved by technology

[0007] The present invention is aimed at the prior art, when retrieving image data in the PACS system with a large amount of data, especially when multiple image workstations are retrieving at the same time, the workload of the database server rises sharply, the system speed decreases, and the overall cost increases To solve this problem, provide a medical imaging database retrieval method based on caching technology to speed up image data retrieval, reduce the workload of the database server, and improve the work efficiency of the PACS system
