Description
Technical Field
The invention belongs to the technical field of medical data management, and particularly relates to an MR scanning data storage method, a DICOM router and a system.
Background
Magnetic Resonance detection (MR) is a detection method commonly used in modern medicine. At high-end medical facilities, sophisticated MR equipment performs scientific scanning tasks in addition to scanning patients. The scanning sequence for these research purposes is complex and the number of images is numerous. If these scientific data are transmitted to the image archiving and communication system (PACS) of the medical institution, they not only occupy the storage space of the system server, but also interfere with the clinical diagnostic task.
In the prior art, in order to avoid the influence of scientific research data on clinical diagnosis, one of the most common methods is to set a special scanning scheme on the MR master station, and then direct the storage space of the scanning scheme to other digital imaging and communications in medicine (DICOM) nodes of a non-PACS system. The storage method of the data depends on the corresponding configuration operation of an operator in each scanning, and the scanning normalization is maintained. This leads to complication of MR scanning operation and inevitably leads to an error in storing path of scanning data due to an operation error. The second method is that scientific research projects are registered separately, and when needing to check scientific research data, checking information can be selected through WORKLIST registered in scientific research; when clinical diagnostic data needs to be reviewed, these lists are systematically masked in the patient lists of a Radiology Information System (RIS) to avoid their interference with the patient diagnostic lists. However, this method requires additional registration of research projects, and research images are still mixed with PACS, wasting storage space of PACS, and still not excluding interference with daily diagnosis due to manual error.
In a word, the existing MR data storage and management method has the problem that scientific research sequences and daily diagnosis data are easy to be confused, and a simple, convenient and complete method for respectively storing and managing the scientific research sequences and the daily diagnosis data still does not exist.
