Description: 这是一个将CT图像序列三维重构的程序，重构后，在颅内预设一条轨迹，并实现自主漫游，效果为两个窗口同时显示，左侧窗口为重构结果和路径即漫游情况，右侧窗口实时显示漫游点正前方切面。(This is a sequence of CT image reconstruction procedure, reconstruction after a preset trajectory in the brain, and achieve independent roaming, effect of the two window shows at the same time, the left side of the window for the reconstruction results and path roaming, the right side of the window display in front of roaming point cut surface.)

Description: 图像重建的最典型的应用是医学上的计算机断层摄影技术（CT技术）。它用于人体头部、腹部等内部器官的无损伤诊断，其基本方法就是根据人体截面投影，经过计算机处理来重建截面图像。在人体中把需要扫描的部分取出一定厚度的断层面，再把断层面分成许多小的方块。当一束较窄的射线通过每个方块后强度就有一定程度的衰减，衰减的量由此方块的分子构成和组织密度决定。如果通过各种角度重复上述过程以获得一系列强度分布曲线，就有可能从这些数据中计算每一方块的衰减量。这样就能够重建断层或三维图像。(The most typical application of image reconstruction is computed tomography (CT) technique in medicine. It is used in the diagnosis of internal organs such as the head and abdomen, and the basic method is to reconstruct the cross-section image according to the projection of the human body. In the human body, the part that needs to be scanned takes out a certain thickness of the fault plane, and then divides the fault plane into many small squares. When a narrow beam of radiation passes through each square, the intensity has a certain degree of attenuation, and the amount of attenuation is determined by the molecular composition and organizational density of the square. If the process is repeated in various ways to obtain a series of intensity distribution curves, it is possible to calculate the attenuation of each square from these data. This allows the reconstruction of a fault or a three-dimensional image.) Platform: |
