  • Patent number: 8189890
    Abstract: Candidate anomalies in an anatomical structure are processed for classification. For example, false positives can be reduced by techniques related to the anomaly's neck, wall thickness associated with the anomaly, template matching performed for the anomaly, or some combination thereof. The various techniques can be combined for use in a classifier, which can determine whether the anomaly is of interest. For example, a computed tomography scan of a colon can be analyzed to determine whether a candidate anomaly is a polyp. The technologies can be applied to a variety of other scenarios involving other anatomical structures.

  • Publication number: 20110103656
    Abstract: A system and method for determining the location and density of plaques in a neuroimage is disclosed according to one embodiment of the invention. In some embodiments, catchment basins are identified as potential plaque areas (candidate regions) in the neuroimage. The Laplacian of each element within the catchment basins can be calculated and the highest Laplacian in the catchment basin identified as a candidate feature. The local contrast can be computed as the ratio between the local minimum of the catchment basin and the average (or some other statistic like the maximum or minimum) intensity of the neighboring watersheds can be used as another candidate feature. In some embodiments, a classifier can be used to discriminate the candidates into plaques or non-plaques, since plaques tend to have a larger Laplacian and larger local contrast than other brain structures.

  • Patent number: 7570802
    Abstract: A three dimensional image of the colon like surface is processed to determine at least its ring structure. The image is composed of vertex points, each vertex point having a discrete point identifier and three dimensional position information. The three dimensional position information is averaged in a shrinking procedure to contract the three dimensional image proximate to a major axis of the colon-like surface. Evenly spaced points are taken through the shrunken colon like surface and connected to form a curve. Planes are generated at intervals normal to the curve to split the shrunken colon like surface into image segments. By mapping these image segments back to the original image through their discrete point identifiers, an accurate ring profile of the colon like surface can be generated.
