Patient Radiation Exposure Monitoring System "onti"

The new system of medical exposure control called “onti” covers a wide range of radiation and radioactivity-based imaging tests. This system covers all elements of X-ray examinations, such as doses in nuclear medicine, and dose control. The system supports not only the recording of doses but also the evaluation, optimization and daily inspection tasks. Digitization provides a consistent sharing of information. As a result, operational efficiency and inspection quality can be improved. It complies with international standardization. “onti” will go one step ahead and strongly support the work of medical exposure dose control. It finds a dose that does not affect the daily diagnostic imaging. We pursue the use of smart information systems that enable us to understand the current situation, solve problems and check the outcome to perform that level of inspection. onti will continue to evolve.

What are the advantages of using onti?

By using this product, accurate medical exposure data can be efficiently recorded and managed without burdening medical staff in accordance with international standard implemented in various countries.

  • Advantages

    • ​​Patient
      • It can be performed at the appropriate radiation dose and radioactivity level according to the individual patient (Body size and Study description).
    • Medical Institutions

      • Medical exposure data can be handled with evidence that is in line with actual conditions, and can be used for research and other purposes.

      • Available for all modalities to which the patient is exposed (CT, DX, NM, etc.).

      • Use small information terminals that are easy to operate and efficient. Medical exposure data and radiopharmaceuticals can be strictly recorded and managed. The burden on medical personnel is extremely reduced.

      • The ability to compare the DRLs (diagnostic reference levels) established by each country with those of your own institution allows you to provide imaging examinations at an international level.

    • ​National Registry

      • ​Electronic data showing medical exposure data and radiopharmaceutical practices and actual conditions can be collected efficiently and widely. This data can thus be used to confirm and revise consistency with guidelines and laws and regulations.

    • Radiopharmaceutical Manufacturers

      • ​Know the proper use of evidence-based formulations, drug discovery, and user trends.
