造句与例句手机版
  • Catheters for medical use - part 7 : determination of the x - ray attenuation of catheters ; requirements and testing
    医用导管.第7部分:导管x射线衰减测定.要求和试验
  • This algorithm uses the profiles collected from a number of angles to compute the x - ray attenuation coefficient of a cross section inside the body , then reconstruct the image of the cross section
    该算法利用从各方向测量出来的投影值求出物体内部受检断面各点的x射线衰减系数,从而重建出整个人体横截面的图像。
  • It is based on the principle : under a number of angles , the x - ray attenuation in a cross section of a human body is measured by detector resulting in a set of profiles . this set of profiles is called the radon transform of the object in mathematics . the problem now is to reconstruct a two - dimensional image via inverting its radon transform
    它所基于的成像原理是:人体的某个剖面在若干个角度上被x射线束照射,照射后x射线的衰减量被检测器记录下来,形成投影集合,数学上将这个投影集合描述为该剖面的radon变换,通过反演radon变换就能够重建剖面的二维图像。
