  • 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.
