One of the reasons for the long treatment time of FUS for HCC compared with RFA is that we have to adjust the target lesion which has a respiratory movement. In this study, we evaluated the usefulness of respiratory tracking system for the FUS monitoring images of hepatocellular carcinoma (HCC).
The respiratory motion trackings for the focal lesions were performed in 6 patients with HCC. The maximum diameter of the tumors measured on sonography ranged from 10 to 50 mm (mean, 25 mm; SD, 5.5 mm). The FUS system (Mianyong Haifu Tech) was used under ultrasound guidance. By using the video images during the FUS treatment, we evaluated the respiratory motion tracking system retrospectively. Template matching method was applied to this respiratory motion tracking software.
