Motion visualization of human left ventricle with a time - varying deformable model for cardiac diagnosis

摘要

We present a time - varying deformable model to visualize and analyze the motion of the left ventricle from a time series of 3-D images. The model is composed of a non - rigid body that deforms around a reference shape obtained from the previous time step. At each time step, the position and orientation of the left ventricle are extracted from the feature points. Of images. This information gives the position and orientation of the coordinate system Attacked to the non - rigid body.
