US 6,351,513 B1 · Fluoroscopy based 3-D neural navigation based on co-registration of other modalities with 3-D angiography reconstruction data

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.

Dependent claims

An imaging apparatus for providing a high-quality representation of a volume having a real-time 3-D reconstruction therein of a movement of an object, wherein said real-time movement of said object is determined using a lower-quality representation of only a portion of said volume, comprising:

first means for acquiring a low resolution image displaying at least one anatomical landmark;
means for co-registering said low resolution image with a pre-stored high resolution reconstruction image on a basis of said at least one anatomical landmark;
second means for acquiring a low resolution real-time 2-D projection image;
and
means for reconstructing a real-time movement of said object in said high resolution reconstruction image.
