  1. Computerized tomography ( ct ) is a typical non - invasive examination techniques in medicine, which can depict anatomical structures without damaging the human body. lt 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 transfoim of the object in mathematics. the problem now is to reconstruct a two - dimensional image via inverting its radon transform

    它所基於的成像原理是:人體的某個剖面在若干個角度上被x射線束照射,照射后x射線的衰減量被檢測器記錄下來,形成投影集合,數學上將這個投影集合描述為該剖面的radon變換,通過反演radon變換就能夠重建剖面的二維圖像。
  2. Reference to the convention means of the analysis and research for energy spectrum hardening and photon scattering in internal and external, and based on the physical mechanism of radial interacts with matter, this paper approximatively deduce a theoretical formula of correction of energy spectrum hardening and scattered radiation in transmission industrial x - ray computerized tomography from a ideal model. and presented a correction computer program

    本文在分析研究國內外有關射線能譜硬化和散射修正問題的分析方法及其研究狀況的基礎上,從射線同物質相互作用的物理學機理出發,從理論上近似推導了x射線能譜硬化和散射修正計算公式,建立了散射修正的分析模型,並編制了相應的計算機修正程序。
  3. The applications of x - ray computerized tomography to geotechnical engineering

    射線技術在巖土工程中的應用
