摘要： A method for defect pre-warning of a power device may comprise processing measurement data regarding components of the power device based on predetermined severity criteria, to obtain severities of one-of monitoring indexes related to defects of the components. Weights of the monitoring indexes with respect to the defects are determined based on effectiveness of the monitoring indexes for the defects. A defect probability that at least one of the components has each of at least one of the defects is estimated based on the severities and weights. Some embodiments may achieve more reliable defect probability estimation and in some embodiments defective component probability and/or device healthy may be estimated. Based on the reliable information, it may facilitate to arrange the maintenance before defects involve into a fault and assess a risk of power device operation and control, thereby improving reliability of the power device.

摘要： A system and related methods for automatic or semi-automatic segmentation and quantification of blood vessel structure and physiology, including segmentation and quantification of lumen, guide wire, vessel wall, calcified plaques, fibrous caps, macrophages, metallic and bioresorbable stents are described, and including visualization of results. Calcified plaque segmentation can be used to estimate the distribution of superficial calcification and inform strategies stenting. Volumetric segmentation and quantification of fibrous caps can provide more comprehensive information of the mechanisms behind plaque rupture. Quantification of macrophages can aid diagnosis and prediction of unstable plaque and associated acute coronary events. Automated detection and quantification of metallic and bioresorbable stents can greatly reduce the analysis time and facilitate timely decision making for intervention procedures.
