摘要:
本文导出了反射模扇形束入射衍射CT的广义断层投影理论,它的前提条件是Born或Rytov近似,且要求物体相对于测量平面的张角很小,在这种近似下,可以证明与点源处于同一平面的测量面上测到的反射场决定了物体断面参数在一旋转椭球面上的频谱值。
Abstract:
A generalized projection-slice theorem is derived for reflection fan beam diffraction tomography within the Born or Rytov approximation which requires that the object being probed subtend a small angle relative to the measurement plane. Within this approximation, it is proved that the reflected ficld measured over the plane in which source point is located determines the three dimensional spatial Fourier transform of the object profile over the surface of an ellipsoid of revolution in Fourier space.
