| Research Abstract |
MR guided Focused Ultrasound Surgery (MRgFUS) is a non-invasive treatment supported by MR anatomical image and MR thermometry. For the MRgFUS of moving organs like a liver, the target tracking technique to “lock on”the focal spot at target tissue region regardless to the respiratory motion is required.In the study, the tracking techniques were proposed and demonstrated based on the displacement and deformation analysis of a liver using multi slice MR images and stereoscopic thick-slab images.
