Respiratory motion tracking system of hepatocellular carcinoma treatment using FUS
نویسندگان
چکیده
Background/introduction 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). Methods 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

A focused ultrasound treatment system for moving targets (part I): generic system design and in-silico first-stage evaluation
BACKGROUND Focused ultrasound (FUS) is entering clinical routine as a treatment option. Currently, no clinically available FUS treatment system features automated respiratory motion compensation. The required quality standards make developing such a system challenging. METHODS A novel FUS treatment system with motion compensation is described, developed with the goal of clinical use. The syst...
متن کاملDynamic MLC Tracking Using 4D Lung Tumor Motion Modelling and EPID Feedback
Background: Respiratory motion causes thoracic movement and reduces targeting accuracy in radiotherapy. Objective: This study proposes an approach to generate a model to track lung tumor motion by controlling dynamic multi-leaf collimators. Material and Methods: All slices which contained tumor were contoured in the 4D-CT images for...

Focused Ultrasound Surgery (FUS) has become a frequent tool for non-invasive benign tumour therapy with FDA clearance for the treatment of fibroadenoma in the uterus and obtained CE mark for sonication of bone metastasis. Other tumours are under preclinical (prostate, kidney) and clinical (breast, brain and liver) evaluation. However, FUS is still challenging in terms of reliable therapy planni...
متن کاملUsefulness of 3D slicer for the planning and monitoring of hepatocellular carcinoma treatment using FUS
Background/introduction FUS is a noninvasive treatment method, as complete coagulation necrosis is achieved without the insertion of any instruments. However, FUS monitor has the poor visualization because of the presence of the multi-reflections, rib shadows and the emergence of the hyperecho after the FUS treatment. 3D Slicer imaging is a diagnostic imaging support system that can provide the...
