    摘要： A method for three-dimensional reconstruction of a branched object from a rotational sequence of images of the branched object includes segmenting the branched object from each image of the sequence, extracting centerlines of the branched object, performing symbolic reconstruction via a stereo correspondence matching between the centerlines from different views of the sequence of images using a graph cut-based optimization, and creating a three-dimensional tomographic reconstruction of the branched object compensated for motion of the branched object between the images of the sequence.

    摘要： A fluoroscopy image is registered with data representing a volume, identifying a catheter position relative to a volume represented by preoperative volume data. The catheter position relative to a patient volume represented by data acquired without scanning the catheter is displayed. For example, a 2D fluoroscopy image is registered with respect to coordinates of a 3D preoperative CT or MRI volume by registering the fluoroscopy image and the preoperative volume to 3D ultrasound coordinates.

    摘要： A method for registering images of multiple modalities includes acquiring first image of a subject using a first modality. A second image of the subject is acquired using a second modality. The first image includes greater structural detail of the subject than the second image and the second image is a video image including multiple image frames. The first and second images are registered based on an anatomical structure observable in the first image and a foreign object proximate to the anatomical structure observable in the second image.
