"3D Augmented Reality Technology Improves the Accuracy of Liver Cancer Surgery"
Oct 11, 2024
Through a joint study, Professor Yoon Kyung-chul and Professor Chae Young-joon of the Thyroid Cancer Center at Boramae Hospital in Seoul Metropolitan Government, run by Seoul National University Hospital, announced that they can reconstruct preoperative CT images of liver cancer patients into 3D augmented reality images and implement them on actual surgical images to accurately identify the location of liver cancer during surgery.
The liver is large in size, the biliary tract and blood vessels in the liver are very complex, and many basins are formed, making it difficult to accurately locate small liver cancer tissues when they are deep in the liver. As a result, it is easy to resect liver cancer without securing sufficient reservation margin, or damage the biliary tract and blood vessels, causing bile leakage or bleeding.
In particular, understanding of the anatomical structure is more important in laparoscopic liver cancer surgery because hands are not available and are dependent on sight. For this reason, various surgical assistance techniques that can visualize anatomical structures have been developed. Among them, the technique using augmented reality has recently attracted attention as a method of intuitively identifying the location of liver structures and liver cancer.
The research team collected CT images of patients who underwent laparoscopic liver surgery for liver cancer at Boramae Hospital from 2021 to 2023 and created a model that implements the location of liver cancer, biliary tract, and liver blood vessels in 3D augmented reality. The researchers worked on overlapping the augmented reality model on the video recorded during actual surgery and evaluated the accuracy of the matched video.
As a result of the study, the researchers were able to match the augmented reality image over the surgical image within an average of 3 minutes, and the matching accuracy reached an average of 93%. This suggests that the application of augmented reality during surgery may contribute to increasing the accuracy of laparoscopic liver cancer surgery.
Professor Kyung-Chul Yoon, the author of the paper, "For safe and effective liver cancer surgery, not only the operator's experience but also various surgical assistive techniques are needed. The liver augmented reality model developed in this study could contribute to increasing the safety of laparoscopic liver cancer surgery in the future."
