5Consistency Conditions for Cone-Beam CT Data Acquired with a Straight-Line Source Trajectory显示文摘A consistency condition is developed for computed tomography(CT) projection data acquired from a straight-line X-ray source trajectory.The condition states that integrals of normalized projection data along detector lines parallel to the X-ray path must be equal.The projection data is required to be untruncated only along the detector lines parallel to the X-ray path,a less restrictive requirement compared to Fourier conditions that necessitate completely untruncated data.The condition is implemented numerically on simple image functions,a discretization error bound is estimated,and detection of motion inconsistencies is demonstrated.The results show that the consistency condition may be used to quantitatively compare the quality of projection data sets obtained from different scans of the same image object.LEVINE Margo S SIDKY Emil Y 2010Tsinghua Science and Technology2010,15,1:1

11Region of Interest Imaging for a General Trajectory with the Rebinned BPF Algorithm显示文摘The back-projection-filtration(BPF) algorithm has been applied to image reconstruction for cone-beam configurations with general source trajectories.The BPF algorithm can reconstruct 3-D region-of-interest(ROI) images from data containing truncations.However,like many other existing algorithms for cone-beam configurations,the BPF algorithm involves a back-projection with a spatially varying weighting factor,which can result in the non-uniform noise levels in reconstructed images and increased computation time.In this work,we propose a BPF algorithm to eliminate the spatially varying weighting factor by using a rebinned geometry for a general scanning trajectory.This proposed BPF algorithm has an improved noise property,while retaining the advantages of the original BPF algorithm such as minimum data requirement.SIDKY Emil Y 2010Tsinghua Science and Technology2010,15,1:1

16Dual-Energy Technique at Low Tube Voltages for Small Animal Imaging显示文摘We investigate the feasibility of dual-energy method for image contrast enhancement in small animal studies using a low kV X-ray radiographic system.A robust method for X-ray spectrum estimation from transmission measurements,based on expectation-maximization(EM) method,is applied to an X-ray specimen radiographic system for dual energy imaging of a mouse.From transmission measurements of two known attenuators at two different X-ray tube voltages,the X-ray energy spectra are reconstructed using the EM-based method.From the spectra information thus obtained,the transmission data for bone and soft tissue in terms of various thicknesses are generated.Two polynomial functions of transmission data are then sought for to fit the inverted thicknesses of bone and soft-tissue.Scatters in cone-beam projection data acquired at two X-ray energies were corrected.From the scatter-corrected data,a bone thickness map is separated from a soft-tissue thickness map by use of the polynomial functions.CHO Seungryong SIDKY Emil Y 2010Tsinghua Science and Technology2010,15,1:1
