Description
Technical Field
The invention relates to the technical field of medical image filing, in particular to a medical image filing method based on mobile medical image equipment.
Background
The system is required to be applied to mobile medical imaging equipment such as shelter CT, vehicle-mounted CT and the like in activities such as emergency disaster relief, health general survey and the like. Because the activity site of the mobile medical equipment is generally far away from the hospital, the activity site can also be limited by local conditions without good network conditions, and images generated by independent external registration need to be matched with an RIS system in the hospital and filed, the process is complex and cannot be finished manually, and the image filing becomes a great problem troubling the mobile medical imaging equipment.
In the prior art, the patient needs to be registered in advance in a hospital, the registered patient information is input into the mobile medical equipment, then scanning is carried out, and then the image is taken back to the hospital for filing. The technology has long execution period, increases the waiting time of patients and has the problem of difficult filing for emergency patients.
Another prior art uses a cloud service technology to synchronize patient information and image data with a server of a hospital radiology department through cloud service. The technology needs a whole set of cloud service system, has high requirement on the network, and can cause image mismatching when the network is unstable.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a medical image filing method based on mobile medical imaging equipment, which is characterized in that the filing is completed by acquiring the patient information in a stored image, matching the acquired information in a RIS by using a worklist technology, matching the patient information, modifying the information such as the patient ID, the registration serial number and the like in the image and using a PACS transmission technology. The invention is simple and easy to operate, has no field limitation, and can conveniently and quickly solve the image filing problem of the mobile medical imaging equipment.
In order to achieve the purpose, the invention provides the following technical scheme: a medical image filing method based on mobile medical image equipment, which obtains local patient information and patient information in worklist for matching, modifies the patient image matched with the information into specific dicommag information, then transmits PACS to finish filing, concretely comprises the following steps,
(1) acquiring images generated by the mobile medical imaging equipment, and acquiring local dicom image information in batch;
(2) reading patient image information in batches and generating a local patient information list;
(3) properly typesetting and storing the patient list into a TXT file for registration of a RIS (RIS) of a courtyard;
(4) acquiring worklist information by one key;
(5) automatically matching local patient information with the patient information;
(6) the PACS transmits the correctly matched patient images to complete the archiving.
DICOM is widely used in radiomedicine, cardiovascular imaging and radiodiagnosis (X-ray, CT, nuclear magnetic resonance, ultrasound, etc.) and is increasingly used in ophthalmology, dentistry, and other medical fields. DICOM is one of the most widely deployed standards for medical information among the tens of thousands of medical imaging devices in use, and there are currently about billions of medical images that conform to the DICOM standard for clinical use.
The DICOM standard covers almost all information exchange protocols of acquisition, archiving, communication, display, query and the like of medical digital images; defining a set of object sets containing various types of medical diagnostic images and related information such as analysis and reports by an open interconnected architecture and an object-oriented method; defining service classes and command sets for information transfer and exchange and standard responses of messages; techniques for identifying various types of information objects are detailed; service support for network environments (OSI or TCP/IP) is provided; the manufacturer's compatibility Statement (compatibility Statement) is defined structurally.
The introduction and implementation of DICOM standard greatly simplifies the implementation of medical image information exchange, promotes the research and development of remote radiology system and image management and communication system (PACS), and makes the integration with other medical application systems (HIS, RIS, etc.) possible due to the openness and interconnectivity of DICOM.
The PACS system is an abbreviation of Picture Archiving and Communication Systems, meaning image Archiving and Communication Systems. The system is applied to a hospital image department, and mainly aims to store various medical images (including images generated by equipment such as nuclear magnetism, CT, ultrasound, various X-ray machines, various infrared instruments, microscopes and the like) generated in daily life in a digital mode through various interfaces (analog, DICOM and network), can be quickly called back for use under certain authorization when needed, and is added with auxiliary diagnosis management functions. It has important roles in transmitting data and organizing and storing data among various image devices.
WorkList service: once the patient information is input, other workstations can be directly and automatically called from the PACS system main database without manual input again; the medical imaging equipment with the WorkList service can directly extract the basic information list of related patients from the server, and the imaging equipment without the WorkList function can input information data of the patients through the operating console of the medical imaging equipment or extract registration information through the diagnosis separating console.
In conclusion, the invention can extract the patient information through the Dicom image information, has the function of worklist, and can be docked in the RIS system of the hospital, modify the image information and finish archiving. The patient image generated by the mobile medical imaging equipment in the off-line environment is filed in the hospital patient data storage system, and the mobile medical imaging equipment can be flexibly adapted to the medical imaging data and the hospital data storage system on the market. The invention is simple and easy to operate, has no field limitation, and can conveniently and quickly solve the image filing problem of the mobile medical imaging equipment.

3. the PACS information is configured, the patient image is automatically matched, and the filing is finished
1) A PACS configuration interface is provided for a user to configure AET-related information of a hospital PACS, and a DicommochoRequest is used to judge whether the PACS system is successfully connected.
2) An automatic filing button is provided on the main interface for users to click to finish filing:
the program automatically matches the local image data information with the patient information of worklist from RIS, preferably using (0010) the paintentame for matching. In consideration of the situation that the duplicate names may occur, the invention can carry out one-time duplicate name screening in advance and put forward the duplicate name for further matching. Further matching is done by judging the same person's (0010,0030) PatientBirthDate if (0010,0030)
If the PatientBirthDate is the same, then the patient is considered not to be matched automatically, and the patient is indicated as failed. Successful auto-matching archives will show success at the interface.
4. And manually matching the patient image to finish archiving.
For patients who cannot be automatically archived, namely (0010,0030) PatientBirthDate and (0010,0030) PatientBirthDate are the same, the invention provides a manual matching function for users to click on for manual matching and archiving.
