Abstract

The invention discloses a retrieval system based on a multi-lesion region characteristic and oriented to a medical image database. In the invention, the image is omni-directionally described by advanced image description symbols, including image region contents, pathological representation and anatomical position information, thus realizing the quick positioning and matching method on a plurality of lesion regions; by adopting the method of combining the semantic navigation and high-dimension data index, the quick retrieval of large-scale image characteristic value can be realized, the retrieval efficiency is improved, and the 'semantic gap' phenomenon existing in the traditional image retrieval technology is relieved to certain degree. The retrieval system sufficiently utilizes the historical image and diagnosis data in a PACS (picture archiving and communication system) database, can be used as an effective measure for computer aided diagnosis, and can be widely applied to the fields such as medical clinics, researches and teaching.

Description

technical field [0001] The invention belongs to the field of medical information technology and information retrieval technology, and specifically relates to a retrieval system based on multi-focus area features for medical image databases. Background technique [0002] The key core system of medical imaging informatics and its engineering application is medical image archiving and communication system (PACS). PACS integrates the collection, communication, processing, storage and display of medical images, and is a key information system and technical support platform for hospitals to realize digitalization. With the development of medical imaging technology and the popularization of medical information systems, the radiology department of a modern hospital will generate a large number of radiological images every day, which are used by doctors for clinical diagnosis, disease tracking, operation planning, prognosis research, and differential diagnosis. important objective b...
