RayMed has been selected for the IP-R&D strategy support project led by the Korean Intellectual Property Strategy Development Institute. We have completed the filing of relevant domestic patents and we are now looking to submit international patents in the United States and Europe through the PCT in the latter half of 2024.

Product and Technology

OnDOSE™, by RayMed, provides accurate assessment of absorbed dose in patients undergoing radiopharmaceutical treatment and tailors treatment plans to each individual patient.

Our model

Revolutionizing Radiopharmaceutical Treatment: Tailored Dosing with OnDOSE™

By combining AI with mechanical and mathematical modeling to assess patient medical images, our software can provide accurate absorbed dose measurements and enable medical professionals to establish patient-tailored treatment plans on-site.

Patients can also gain a better understanding of dosage and treatment response after radiopharmaceutical treatment. Collectively, this can allow medical institutions to establish comprehensive and integrative radiopharmaceutical usage and assessment guidelines.

How it works

Using Image Data for Precise Treatment with OnDOSE™

OnDOSE™ analyzes patient image data transmitted through the hospital’s internal Picture Archiving and Communication System (PACS) to visualize predicted biodistribution and to assess precise absorbed dose which can aid medical professionals to establish precise treatment plans.


Rapid Dose Calculation: AI's Impact on Treatment Speed

Conventional Monte Carlo-based techniques require at least two to four weeks to calculate radiation dose. However, the use of artificial intelligence can significantly accelerate this process, allowing crucial dosimetry measurements to be made within a minute; thus, greatly enhancing the effectiveness and cost efficiency of radiopharmaceutical treatment for patients.
