摘要： A method and system for spatio-temporal (4D) modeling of an object includes sampling the 4-D model at one point in time to create a 3-D model. This 3-D model is then fit based on user-supplied guide points, image forces (e.g., image edges) and prior shape models. Once the 3-D model fit is completed the full 4-D shape model is updated. Cardiac images can be spatio-temporally modeled to determine LV conditions.
