Overview

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).

Features

  • It can automatically delineate 163 normal organs and 27 lymph nodes.1)
  • Compared with conventional manual work, it significantly reduces the time required for contouring and minimizes variability between treatment planners, thereby improving the efficiency of radiation treatment planning and supporting precise, patient-specific radiation therapy.2)
  • The results of automatic contour delineation are completed in approximately several tens of seconds to around 2 minutes1)compared with the several hours typically required for manual processing. The processing speed depends significantly on the number of slices and the number of organs being delineated.

1. Efficiently achieve image segmentation.

Since 2022, AI-powered automated contouring has been used to generate more than 4 million contours across the treatment of 80,000 patients. With its unparalleled accuracy and reliability, and its proven ability to consistently enhance the quality of radiation treatment planning, it is setting a new standard in patient care. A technology proven in clinical practice.
