Abstract

The present invention proposes a method for analyzing DICOM files in a file directory, which includes inputting a file directory, comparing its file structure with the file storage structure record, and obtaining the changed part. The file storage structure record saves the accessed file directory The file structure of the file; the change part is merged into the file storage structure record; the analysis result of the change part is merged into the DICOM file storage structure record, and the DICOM file storage structure record saves the DICOM file analysis result of the accessed file directory; from DICOM The file storage structure record obtains the DICOM file storage structure of the input file directory. The present invention saves the file structure of the accessed file directory and the corresponding DICOM file analysis results, so that only the changed part needs to be analyzed during re-access, and the resolution speed during re-access is accelerated.

Description

technical field [0001] The invention belongs to the technical field of medical images, and in particular relates to a method for analyzing DICOM files in a file directory. Background technique [0002] DICOM (Digital Imaging and Communications in Medicine) is an international standard for the transmission, storage, retrieval, printing, processing and display of medical imaging information. DICOM files are image files saved according to the DICOM standard, including CT, MRI, ultrasound and other types of medical image files. [0003] Usually, one examination of a patient includes multiple sequences such as CT images and MRI images, and each sequence consists of multiple high-resolution DICOM images. For example, a DICOM image of a CT scan can reach hundreds of MB. In research related to medical images, the research data often contain DICOM image data of hundreds or thousands of patients in different periods. [0004] At present, when DICOM image processing software opens t...
