Embodiment Construction

[0024] The invention provides a content-based retrieval method for radiographic images in a PACS database. Through the integration between RIS and PACS, the radiological diagnosis report in RIS is associated with the radiological image in PACS, and the inverted index of radiological diagnosis report and the feature index of radiological image are respectively established, and then the "two-stage search" algorithm is used to search Query requests for content-based image retrieval. A valid query request consists of at least an image example and image example-related text description information, where the image example is a PACS image specified by the user, and the image example-related text description information is the imaging manifestation or / and possible pathology of the image example A textual description of the diagnosis. In addition, the query request may also include the patient's basic identity information (patient's name, gender, date of birth, etc.) and imaging exam...

Abstract

The invention discloses a content-based retrieval method and a content-based retrieval system facing radiographs in a PACS database. The content-based retrieval to the radiographs is realized by associating a radiodiagnosis report in a radio information system with the radiographs in the PACS database, establishing the reverse index of the radiodiagnosis report and a feature index library of the radiographs, and then using a two-phase search algorithm. The retrieval method, by effectively integrating text retrieval technology and content-based image retrieval technology, overcomes the defect that the prior content-based image retrieval technology is not suitable for large-scale image databases, alleviates the semantic gap in the prior content-based image retrieval technology to a certain extent, and has high application value.

Description

technical field [0001] The invention belongs to the technical fields of medical information technology and information retrieval, and in particular relates to a content-based retrieval method and system for radiographic images in a PACS database. 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 objec...
