研究室紹介
Professor Jong-Yoon Won's research lab specializes in interventional radiology and medical robotics, focusing on minimizing radiation exposure for both patients and clinicians through the development of advanced robotic systems for vascular interventions. The lab investigates image-guided interventions such as transarterial chemoembolization (TACE) for hepatocellular carcinoma, with an emphasis on reducing complications like hepatic arterial damage. A key research direction involves the integration of deep learning and automation in vascular intervention robots to enhance precision and reduce operator workload. The lab also explores safe and effective percutaneous procedures, such as fluoroscopy-guided gastrostomy, particularly for neurodegenerative disease patients.

15Background Transarterial chemoembolization (TACE) of hepatocellular carcinoma (HCC) frequently causes feeding artery stenosis or occlusion that may interfere with repeated treatment. Purpose To investigate the incidence and predictors of hepatic arterial damage (HAD) after drug-eluting bead-TACE (DEB-TACE) in comparison with conventional TACE (Conv-TACE). Material and Methods We retrospectively analyzed 54 patients who underwent DEB-TACE for HCC as an initial treatment with follow-up angiography
Abstract Manual vascular interventional radiology (VIR) procedures have been performed under radiation exposure conditions, and many commercial master–slave VIR robot systems have recently been developed to overcome this issue. However, master–slave VIR robot systems still have limitations. The operator must reside near the master device and control the slave robot using only the master device. In addition, the operator must simultaneously process the recognition of the surgical tool from the X-
Conventional vascular intervention (VI) procedures are typically performed manually under exposure to X-rays, whereby several problems are presented that need to be addressed owing to the patients and doctors being exposed to large amounts of radiation. In such cases, employing radiation protection units is not a long-term solution to avoid physical damage. Therefore, to overcome these issues, we propose a robotic VI system in this study. Moreover, we compare the extent of radiation exposure in
BACKGROUND: The purpose of this study was to evaluate the safety and usefulness of fluoroscopy-guided percutaneous gastrostomy (FPG) in patients with amyotrophic lateral sclerosis (ALS) using a large-profile gastrostomy tube accompanied by the pull technique. This procedure was done without an accompanying endoscopy or gastropexy. METHODS: Thirty-six patients with ALS underwent FPG using a large-profile gastrostomy tube accompanied by the pull technique. A 24 Fr pull-type tube was inserted under
