本文提出了一种基于模型的医学图像分析方法。其目的是了解图像内容背后的生理（与组织相关）和物理（与图像模态相关）过程的影响。这种方法是例示建模第一，肝脏及其血管网络，第二，标准的计算机断层扫描（CT）扫描acquisition.After血管建模文献的简要调查，一种新的方法，旨在产生不断增长的三维血管结构灌注的组织，被描述。提出了一种解决方案，以避免属于生理上连接的动脉和/或静脉树的血管之间的交叉。然后，它是如何传播的对比材料导致模拟增强肝脏CT切片的时间依赖性序列。
In this paper, a model-based approach to medical image analysis is presented. It is aimed at understanding the influence of the physiological (related to tissue) and physical (related to image modality) processes underlying the image content. This methodology is exemplified by modeling first, the liver and its vascular network, and second, the standard computed tomography (CT) scan acquisition.After a brief survey on vascular modeling literature, a new method, aimed at the generation of growing three-dimensional vascular structures perfusing the tissue, is described. A solution is proposed in order to avoid intersections among vessels belonging to arterial and/or venous trees, which are physiologically connected. Then it is shown how the propagation of contrast material leads to simulate time-dependent sequences of enhanced liver CT slices.
