Embodiment Construction

[0037] The technical solution of the present invention will be further elaborated below in conjunction with the accompanying drawings.

[0038] A method for reading DICOM file information and image format conversion, comprising the following steps:

[0039] Step 1: by figure 1 The specific file format of the DICOM file can be known, so that the DICOM file can be read through bytecode processing;

[0040] Step 2: Extract and save the PHI information in the file, and finally save it in the form of a data group, such as figure 2 shown;

[0041] Step 3: Extract the medical image in the file, convert it to jpg format and save it, such as image 3 shown.

[0042] Step 1 specifically includes:

[0043] 11) Pass in the DICOM file, and open the file in the form of a binary string;

[0044] 12) Skip the preamble part of the preset byte at the beginning of the file, and then read whether the 4-byte prefix part is "DICM" to determine whether it is a DICOM format file;

[0045] 13)...

Abstract

The invention discloses a DICOM file information reading and image format conversion method. The method comprises the steps: 1, reading a DICOM format file; 2, extracting and storing PHI information in the file; and 3, extracting a medical image in the file, and converting the medical image into a jpg format for storage. The invention provides the DICOM file information reading and image format conversion method based on the existing requirements. The PHI information in the DICOM file is read and stored, and the medical image in the DICOM file is converted into the common jpg format to be stored. According to the method, the DICOM file can be processed, and the PHI information of a patient in the DICOM file is extracted and stored as a data group; and the medical image data in the DICOM file can be extracted and stored in the jpg format, and subsequent use is facilitated.

Description

technical field [0001] The invention relates to a method for reading DICOM file information and image format conversion. Background technique [0002] DICOM (Digital Imaging and Communications in Medicine) is an international standard (ISO 12052) for medical images and related information. It defines a medical image format that can be used for data exchange with a quality that meets clinical needs. [0003] DICOM is one of the most widely deployed medical information standards, revolutionizing the practice of radiology and enabling advanced medical imaging applications. Medical images of patients are stored in DICOM file format. This format contains PHI (protected health information) information about the patient, such as name, gender, age, and other image-related information, such as information about the device that captured and generated the image, some medical context-related information, and so on. [0004] In medical practice, doctors usually use DICOM readers to re...
