| Abstract(in English) | We propose a method for recovery of the liver motion and deformation by using a laparoscopic freehand 3D ultrasound system. Our method estimates in-plane deformation from time series of 2D ultrasound images. Each 2D image is tracked by a miniature magnetic tracker attached to the ultrasound probe tip so that spatial relationships among them are acquired. Therefore, the time series of 3D deformation is estimated by interpolating the in-plane deformation measured at several place. The proposed method applied to the ultrasound images of the pig liver, and then we confirmed its feasibility. |
