Abstract
A method and apparatus for providing a high-quality representation of a volume having a real-time 3-D reconstruction therein of movement of an object, wherein the real-time movement of the object is determined using a lower-quality representation of only a portion of the volume. The merger of 3-D angiography image representations acquired with other modalities, such as MR or CT, is disclosed. MR or CT modality images are registered with the 3-D Angiography data, such that those other images are brought into the same coordinate frame as the 3-D Angiography images. Movement of the object is detected in a 2-D X-ray fluoroscopy image and is reconstructed in a 3-D mode.
