Abstract

The invention relates to a medical image authentication preservation method based on data integrity checking and restoration. The method comprises the following steps: (1) shooting a DICOM (Digital Imaging and Communications in Medicine) image by imaging equipment of a data preservation system, and directly inputting the image to the system; (2) extracting and preserving the DICOM digital image data and generating a preserved data packet by the data preservation system; (3) sending the preserved data packet to a remote data authentication system according to a user request; (4) identifying the data by the data authentication system, directly transforming the unpreserved image data into a DICOM standard format, and certifying the preserved data, namely the preserved data packet; (5) during the authentication of the preserved data packet, performing on-line data restoration on a data segment with errors by network connection between the data segment and the data preservation system; (6) reducing the authenticated complete data or the on-line restored complete data into the DICOM standard format by the data authentication system. The method has the advantages of being capable of guaranteeing the authenticity and reliability of the image data in telemedicine and providing technical support for breaking information encapsulation among hospitals and realizing data share.

Description

technical field [0001] The invention belongs to the technical field of telemedicine, and relates to a medical image authentication and preservation method based on data integrity verification and restoration. Background technique [0002] With the introduction and realization of the DICOM3.0 standard (version 3.0 medical digital imaging and communication standard), and the support of international mainstream medical imaging equipment manufacturers for this standard protocol, the remote data transmission technology of medical digital imaging between hospitals has been developed. With the application, telemedicine based on medical imaging information can be realized. [0003] The DICOM3.0 protocol has realized the standardization of communication transmission of medical digital images, and established a medical image storage and transmission system (PACS: Picture Archiving and Communication System) on this basis, that is, each patient will generate a digital image after each f...
