Medical Exposure Management Information System


The new system of medical exposure control "onti" covers a wide range of imaging examinations using radiation and radioactivity. The system covers all elements of X-ray examinations, including doses in nuclear medicine examinations, and dose management. It supports not only dose recording, but also evaluation, optimization, and routine inspection tasks. Digitization enables consistent information sharing. 

As a result, improved operational efficiency and inspection quality can be expected. International standardization is also supported. "onti" is one step ahead and strongly supports the work of medical exposure dose management.

It finds the dose that does not affect daily diagnostic imaging. To perform examinations at that level, we pursue the use of smart information systems that allow us to understand the current situation, solve problems, and confirm results. onti will continue to evolve.

Academic research using onti:



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.
