摘要： A system and method for segmenting and editing anatomical objects from medical images is disclosed. The system may be a medical diagnostic imaging system. A computer unit may execute computer software for segmenting anatomical objects from medical images. The computer software may extract an anatomical object from planar curves. The computer software may extract an anatomical object by computing the centerline of the anatomical object. A set of reformatted images may then be derived based on the centerline of the object. A user may then provide input in the form of user drawn contours on a plurality of reformatted images. In an embodiment the reformatted images may include a reformatted longitudinal view, a curved reformatted view, or a lumen view. The user drawn contours may correspond to the boundaries of the anatomical object to be segmented. The anatomical object may then be extracted based on the user drawn contours.

摘要： A method for analyzing a three-dimensional (3D) image representative of an initial volume of interest (VOI) containing a lesion is disclosed. The 3D image has an associated binary map having voxels associated with a thresholded variance map of the initial VOI. The initial VOI has boundaries that may be defined by a cube. A final VOI is determined that is less than the initial VOI, where the final VOI is a function of the number of transitions from a boundary voxel to a filtered voxel at an outer boundary of the lesion. The final VOI is then analyzed to determine a nodule consistency class, classified based upon the computed nodule consistency class by applying a voxel-clustering algorithm, and displayed with respect to three classifications of tissue.

摘要： The preprocessing methods of this invention remove the data relating to the cavities of the heart, and improve the density mix of the parts left therein during CT imaging, so as to allow coronary arteries to be more accurately tracked with conventional tracking algorithms than currently possible. An embodiment comprises: obtaining an original CT voxel dataset comprising a plurality of voxels; creating a heart voxel dataset from the original voxel dataset comprising only voxels belonging to the heart; creating a heart minus cavities voxel dataset by removing voxels belonging to the left and right ventricles, the left and right atriums, and the aorta from the heart voxel dataset; enhancing predetermined voxels in the heart minus cavities voxel dataset to create an enhanced heart minus cavities voxel dataset; and mixing an intensity of the original CT voxel dataset with an intensity of the enhanced heart minus cavities voxel dataset to create the pre-processed voxel dataset.
