This system needs to be able to connect to PACS as well as HIS.
  • Deployed at the service registration, administration and management department of the diagnostic imaging department
  • The RISLink system, built by Viet Ba, is highly compatible with other IT systems in the hospital as well as the habits of Vietnamese people. The system has a customizable interface, allowing you to choose Vietnamese language and any other language, so it is very suitable for many different users.
  • Model of information circulation of the system:

  • This system basically includes the following functions:
    • Reception management, registration of patients in the department: Allows the administrative department of the CDHA department to update administrative information and service orders for patients registered directly at the department

  • Connect with other systems such as HIS (patient administration information and scan orders, service performance results, diagnosis results, ...). This function prevents the administrative department of the department from having to re-input the patient's administrative information and service orders if they have been recorded in the general registry of the hospital.
  • Turn administrative information and capture commands into modality: This system has features that allow connection with diagnostic imaging devices to automatically transfer patient information to DICOM WORKLIST compliant equipment. With this feature, the RISLink system will help minimize technician's equipment operating time, eliminating the need for technicians to re-enter patient information (name, age, address, shooting location, ...) into the device. This feature, together with HIS Connect feature, help ensure a complete management process in hospital imaging.

 (The list of patients via RISLink via DICOM WORKLIST transferred to the DR system of CANON)

  • Statistics, reports for the management of the CDHA faculty: The system allows to synthesize reports according to many criteria (Object, service, ...). Simultaneously allow display in many different types of reports (graphs, lists, ...)

  • Connect with PACS system to look up, monitor service performance, and diagnose results. Information about the processing status of the image can also be immediately transferred to other management systems (clinic management, hospital fees, ...) to calculate general costs for the patient. Immediately after the images were collected, the PACS system also transferred all of these images and the diagnostic results of the CĐHA doctors to the photo viewing stations of clinicians to support medical examination The patient is quick and accurate.
