64-slice Volume CT 层容积CT
The transepicondylar axis of different position has no effect on volume rendering technique measuring the humeral head retroversion angle with multi slice spiral CT.
肱骨远端不同位置内外上髁轴线对多层螺旋CT容积再现测量肱骨头扭转角没有影响；
When Volume CT scan is processed to industrial product, there are some position and orientation problems. Therefore registration between industrial product's CT slice model and CAD model is necessary.
在对工业产品进行体积CT扫描时，会存在定位偏差问题，所以工业产品CT切片模型与其CAD模型之间的配准是必不可少的。
The geometric error of axial image reconstruction increases with the increase of CT scan slice thickness, due to CT partial volume effect.
重建CT图像的前后方向的几何误差是随着扫描层厚增加而增加，主要是由于CT扫描的部分容积效应影响。
