OncoStudio obtained medical device approval from the Korean Ministry of Food and Drug Safety in February 2022 and has been implemented at 16 major hospitals in Korea, including Samsung Seoul Hospital, Severance Hospital, and Seoul National University Hospital. Accurate organ delineation is extremely important in radiation therapy planning. This program utilizes AI based on deep learning algorithms to automatically delineate organs from patient CT images with high speed and accuracy. It also complies with the DICOM standard and is compatible with commercially available hardware and software used in radiation oncology departments.
In addition, Anzai Medical Co., Ltd. obtained certification for the manufacture and marketing of specially designated highly controlled medical devices on April 10, 2025 (Certification No. 307AFBZX00029000).
