A low-injury, high success rate, and no side effects treatment for curing heart physical defects is urgently needed in the medical field. Although with electrocardiographically (ECG) gated technology, the timeline information of heartbeat can be collected by Multi-detector Computed Tomography (MDCT), the traditional CPU-based volume rendering methods can not meet the dynamic cardiac real-time reconstruction...
Nowadays, 3G netowrk plays a very important role in mobile communication system. But the security concern of such network, especially the core network, is far from being satisfied. GPRS Tunnel Protocol(GTP), which is one of the key protocols in the core network, is quite vulnerable to attacks in the flat, full IP environment. Therefore solving such problem properly is very urgent and important for...
This paper introduces the simple liner transparent model and nonlinear transparency model which based on Z component. It analyses the disadvantage which existed in the Z component and brings forward an algorithm of nonlinear transparent display model which based on bounding box. The experiment shows that we can conquer the shortcoming which generated by nonlinear transparent model that based on Z...
A pulmonary nodule is relatively round lesion, or area of abnormal tissue located within the lung that can be seen in thoracic CT scans. Because noise and same like disturbance of blood vessels and tracheas, detection of the lung nodule is difficult. A three-dimensional pulmonary nodule detection method for thoracic CT scans is proposed in this paper. First, bounding box method and three-dimensional...
In this paper, authors propose a new learning based method for medical image retrieval which is based on fusing different features by linearly combining different similarities. Considering the abundant classes of medical images, this paper avoid to train a classifier for each class by using large amount training data. Instead, by using optimization method to combine different features' similarity,...
Form is the information media in the application system and becomes very important in the daily business processing, especially in the workflow enviroment. In this paper, we analyze the form related concepts, elements and show how to implement a form system with a real form system, call UniEAP Form. To play a full power in application systems, we address how the form system can be leveraged in a workflow...
This paper firstly preprocesses CT images using a dot enhance filter which can enhance some round-like nodule tissues and at the same time, restrain interference from tissues of other shapes(for example, linear vessels). Then, the paper adopts a feature space optimization design theory to select seven effective features from twelve original candidate features and regards the combinations of the seven...
The detection of lung nodules is a difficult problem in the field of medical aided diagnosis, due to the noise and the disturbance of blood vessels and tracheas. According to this problem, this paper brings forward a Circle filter algorithm based on the anisotropy smoothing equations. Firstly, a circle smoothing equation is deduced by means of the anisotropy smoothing equations and Hessian matrix...
