Digital medical infrastructure and application software to share

Basic structure

Digital medical regardless of future developments are based on existing technology-based, future hospital functions no matter how powerful, it is a basic structure, the structure simple grouped into 4 parts-digitization of medical equipment, digital equipment of the network, the network of digital medical system, as well as on digital medical system services.

Digital medical equipment

Digital imaging devices, such as CT, MRI, CR, DR, ECT, etc, are digitized medical equipment.

They have met DICOM3.0 (the main provisions of the digital medical images and related information in the format and method of standards for information exchange) standard interface, you can directly from the digital interface acquisition image data, and PACS connectivity easier; for earlier use of digital devices, as no standard DICOM interface, all manufacturers of digital formats and compression in different ways, the problem can be solved interface for the connection. For analog image acquisition, recent DICOM standard has its own requirements. With the constant DICOM3.0 interface widespread application and the international industry standard HL7 (Health Level7, mainly in the medical environment of electronic data exchange standards), the past different manufacturers of medical equipment to organic links, and HIS true form blends, information sharing network, digitized, facilitate the clinical departments of query and call.

Application software system

Hospital information management system (Hospital Information System, HIS)

Hospital information management system is an important component of digital medical enables clinical departments and easier to handle and use a variety of clinical data, such as the patient's doctor's advice, the course record, medicines, laboratory results, medical expenses, etc.

HIS should include the following subsystems: outpatient fee management, basic prices pharmacy management, pharmacy management, out of the hospital management, disease management, medical management, electronic pathology test results management, etc. Now the hospital's "Army", project "and" Jinwei project "is part of the system as a model for a successful application.

Medical image archiving and communication system (Picture Archiving and Communication System, PACS)

Medical image archiving and communication system is a clinical medicine, medical imaging, digital imaging technology and computer technology, network communication technology products, it would be medical information into the computer to recognize the digital form, through the computer and network communication equipment, complete information on medical images and related information (data) for the acquisition, storage, processing and transmission, and other features that enable sharing of medical information resources, and be fully applied.

It enables clinicians to quickly and accurately to the needs of medical imaging information and related medical imaging diagnostic reports, medical information, patient records, clinical examination (examination), reporting, treatment records and other information, as well as query and the medical imaging related images in a variety of imaging equipment, information in order to do a comprehensive and integrated medical image analysis, clear diagnosis and develop appropriate treatment plan.

Radiology information system (RIS, Radiology Information System), radiology information system primarily for Radiology departments manage, retrieve patients arrangements, photos, records, etc.

Complete RIS included starting from patient access to radiology all text information records, Radiology Department's everyday work management, statistical and scientific research of cases.

HIS, PACS and RIS three relations

HIS and RIS holds the patient's demographic information and clinical data, save and pass the patient information that the image of the graphic.

Save the patient's PACS main image data, also uses HIS and RIS in the patient information, from HIS and direct access in the RIS can avoid duplicate entry, reduce errors. In the writing diagnostic report and review, workstation in display patient images, it is also able to show HIS and RIS patient clinical data of all kinds; a clinician can also be seen in HIS patient's check image, to information sharing.

Do the imaging, patient information from HIS and transferred to the RIS PACS in; for had imaging of patients, with the advent of patient information, PACS to long-term preservation of images retrieve callout to write report of workstation for before and after.

Check is finished, the image and diagnosis reports then passes back to HIS and RIS, clinicians can immediately see.
