    摘要: An apparatus for automatic selection of optimal tomography slices by executing a number of tentative segmentations using the same interactively provided in-slice seed point on some or all available tomography slices. The appropriate segmentation boundaries are then marked and the slice with the best segmentation goodness value (figure of merit) is presented to the user via a viewer. The steps are repeated when the user changes the seed point. The optimal segmentation boundary is displayed on top of a single simulated mammography image, fused from all tomography slice images.

    摘要: When characterizing a tumor or lesion as malignant or benign, a system (10) receives an image of the lesion volume (50), employs a processor (12) to perform a raw segmentation of the image, the results of which are stored to memory (14). Then processor then executes a hole-filling procedure to fill in dark areas in the image of the lesion representing necrotic tissue that absorbed little or no contrast agent, and optionally a leakage removal procedure to remove image voxels associated with non-lesion tissue, e.g., blood vessels, in which the contrast agent was present during imaging, to generate a complete lesion volume. A voxel analyzer (18) assesses a number of voxels included in the raw segmentation of the lesion image, and the final segmentation (e.g., after filling and optional leakage removal). A segmentation comparator (20) computes a ratio of dark area voxels related to necrotic tissue detected after the raw segmentation to total voxels detected in the final image segmentation. The ratio is then used to determine a likelihood of malignancy, with a higher ratio indicating a higher likelihood.

    摘要: An automated method (1) for the automatic extraction of a pulmonary vessel tree from a 3D medical image, such as multi-slice CT data, is disclosed. A segmented pulmonary vessel is identified as either an artery or a vein by determining a measure for arterialness for the vessel. The measure is based on a relation of the orientation of a local bronchus to the orientation of the segmented pulmonary vessel of the local bronchus. When a vessel is identified as a pulmonary artery, it is added to the pulmonary artery tree. Radii of the pulmonary artery and bronchus are measured automatically and positions where a ratio of these radii exhibits unusual values are presented in a display, preferably for suggesting further assessment by a radiologist, which for instance is useful for pulmonary embolism detection.

    摘要: The invention relates to a method and an image processing device (10) for the evaluation of image raw-data of a body region generated with an imaging device like a CT scanner (30). From the image raw-data, a first image (ICAD) is reconstructed with a reconstruction module (12) according to reconstruction parameters (p) set optimally by a computer aided detection and/or diagnosis (CAD) module (13). This module can then evaluate an image (ICAD) that was reconstructed optimally according to its own requirements, for example with respect to image size and/or resolution, to find features of interest.
