Библиографическое описание: Trinh V. B. The Selection of Computed Tomography Scanning Schemes for Lengthy Symmetric Objects / V. B. Trinh, Y. Zhong, S. P. Osipov // IOP Conference Series: Materials Science and Engineering. — 2017. — Vol. 189 : Modern Technologies for Non-Destructive Testing : 5th International Conference, 3–8 October 2016, Tomsk, Russian Federation : [proceedings]. — [012024, 5 p.].
Аннотация: The article describes the basic computed tomography scan schemes for lengthy symmetric objects: continuous (discrete) rotation with a discrete linear movement; continuous (discrete) rotation with discrete linear movement to acquire 2D projection; continuous (discrete) linear movement with discrete rotation to acquire one–dimensional projection and continuous (discrete) rotation to acquire of 2D projection. The general method to calculate the scanning time is discussed in detail. It should be extracted the comparison principle to select a scanning scheme. This is because data are the same for all scanning schemes: the maximum energy of the X–ray radiation; the power of X–ray radiation source; the angle of the X-ray cone beam; the transverse dimension of a single detector; specified resolution and the maximum time, which is need to form one point of the original image and complies the number of registered photons). It demonstrates the possibilities of the above proposed method to compare the scanning schemes. Scanning object was a cylindrical object with the mass thickness is 4 g/cm2, the effective atomic number is 15 and length is 1300 mm. It analyzes data of scanning time and concludes about the efficiency of scanning schemes. It examines the productivity of all schemes and selects the effective one.
