A Method for Accurately Anonymized Storage and Retrieval of Medical Images

Abstract

A method for accurate anonymized storage and retrieval of medical images, comprising the following steps, the first part, establishing a patient medical image database, including the following steps: Step 1, collecting patient information big data, collecting medical images of a large number of patients through cooperative hospitals, Use statistical methods to analyze the data of the human body characteristics and diseases reflected in the patient's medical image information; Step 2, generate an index, and generate an index header from the information in the human body characteristics and disease preparation database in Step 1 according to the irreversible compression algorithm; Step 3, Anonymization processing; Step 4, store in an anonymous database. The second part, according to the patient information required for research and development, collects information through retrieval of anonymous databases to improve the efficiency of medical data query, including two steps of index generation and data acquisition. The invention has the characteristics of safety and applicability, has good popularization and practical value, and can produce good economic benefits after being widely popularized and applied.

Description

technical field [0001] The invention belongs to the technical field of anonymizing the preservation and transmission of patient medical image data sets, and in particular relates to a method for accurate anonymized storage and retrieval of medical images. Background technique [0002] Strict rules exist for the security of image storage in healthcare, which precludes storing such data in external data centers. Existing technologies can use some anonymized preservation methods to adapt to this rule, but the problem is that when using existing technologies, the data cannot be well classified for processing, that is, it is impossible to obtain similar data from the data under management. data, and this demand is very important for big data processing. [0003] With the development of economy and society, medical image diagnosis is accepted by more and more people. The diversity of diagnosis modalities and treatment methods and the increase in usage rate make the amount of pati...
