Abstract

The invention provides a DICOM file access method and device; the method comprises the following steps: inputting a DICOM file; determining whether a DICOM file index has a corresponding record or not in a file information table; if yes, creating a file index link in a file index relation table so as to link the DICOM file index to an DICOM file upper file index; if not, storing the DICOM file in a DICOM file database, creating a record in the file information table so as to link the DICOM file index to a file storage path, and creating a file index link in the file index relation table so as to link the DICOM file index to the DICOM file upper file index. The method and device can effectively reduce DICOM file disk space usage, and can reduce DICOM file access time.

Description

technical field [0001] The invention mainly relates to the technical field of medical image data processing, in particular to a method and device for accessing DICOM files. Background technique [0002] With the popularity of computers and the continuous expansion of hospital scale, the management of electronic medical records of patients has become more and more important. To this end, the American College of Radiology and the American Electrical Manufacturers Association have designated the standard DICOM (Digital Imaging and Communications in Medicine, ie, digital imaging and communication standards in medicine) for medical image storage and communication. The patient examination image files collected and generated by medical equipment conforming to the DICOM standard are called DICOM files. Files in this format contain both patient images and patient information and related exam information. [0003] DICOM models include Patient-Study-Series-Image and Study-Series-Imag...
