20110103656	Quantification of Plaques in Neuroimages - 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.	05-05-2011

20100074491	COMPUTER-AIDED CLASSIFICATION OF ANOMALIES IN ANATOMICAL STRUCTURES - 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.	03-25-2010

20110011163	METHOD FOR TESTING A MECHANICAL INTEGRITY OF AN INSULATING LAYER COVERING A CONDUCTOR IN A CABLE - A method for testing a mechanical integrity of an insulating layer covering a conductor in a cable, a longitudinal void being defined inside the insulating layer in a region of the conductor. A first end of the insulating layer is blocked. A compressed gas is injected at a second end of the insulating layer so that the gas enters and travels the longitudinal void inside the insulating layer towards the first end. A gas pressure inside the insulating layer is measured at least near the second end. Injection of the compressed gas is stropped after a predetermined injection time period. A variation of the gas pressure inside the insulating layer is monitored during a diagnostic time window succeeding to a transitional time period following the stopping of the injection. Integrity of the insulating layer is determined based on the variation of the gas pressure during the diagnostic time window.	01-20-2011
