A new method to measure electron density and effective atomic number using dual-energy CT images.
The purpose of this work is to present a new method to extract the electron density ([Formula: see text]) and the effective atomic number (Z eff) from dual-energy CT images, based on a Karhunen-Loeve expansion (KLE) of the atomic cross section per electron. This method was used to calibrate a Siemens Definition CT using the CIRS phantom. The predicted electron density and effective atomic numbe...

متن کاملDiscussion of Electron Induced Atomic Number Contrast
In this paper, atomic number (Z) contrast from electron induced images is revisited. Z contrast obtained with a scanning electron microscope (SEM) is generally associated with the collection of backscattered electrons (BSEs) and is considered to exhibit a monotonic increase in BSE signal with Z [1]. However, there is no monotonic relationship of the backscattering coefficient, η, with Z at elec...
متن کاملQuantitative Electron Density CT Imaging for Radiotherapy Planning
Computed tomography (CT) is the imaging modality used to calculate the deposit of dose in radiotherapy planning, where the physical interactions are modelled based upon the electron density, which can be calculated from CT images. Traditionally this is a three step process: linearising the raw x-ray measurements and correcting for beamhardening and scatter; inverting the system with analytic or...
متن کاملIodine Vapor Staining for Atomic Number Contrast in Backscattered Electron and X-ray Imaging
Iodine imparts strong contrast to objects imaged with electrons and X-rays due to its high atomic number (53), and is widely used in liquid form as a microscopic stain and clinical contrast agent. We have developed a simple technique which exploits elemental iodine's sublimation-deposition state-change equilibrium to vapor stain specimens with iodine gas. Specimens are enclosed in a gas-tight c...
