Effects of Mechanical Alignment Errors on Compton Scatter Imaging

The development of a prototypc Compton scaltering camera based on two 1 cm3 cubic 3-D position scnsitivc CZT detectors is iindcrway in our laboratory. As a practical problem, the mechanical alignmcnt error may be larger than the 1 mm detector position rcsolution. This paper investigates thc cffccts of any possible mechanical alignmcnt error on the reconstructed images by Montc Carlo simulations...

The Mathematical Foundations of 3D Compton Scatter Emission Imaging

The mathematical principles of tomographic imaging using detected (unscattered) X- or gamma-rays are based on the two-dimensional Radon transform and many of its variants. In this paper, we show that two new generalizations, called conical Radon transforms, are related to three-dimensional imaging processes based on detected Compton scattered radiation. The first class of conical Radon transfor...

Compton back scatter imaging for mild steel rebar detection and depth characterization embedded in concrete

A novel non-destructive Compton scattering technique is described to ensure the feasibility, reliability and applicability of detecting the reinforcing steel bar in concrete. The indigenously developed prototype system presented in this paper is capable of detecting the reinforcement of varied diameters embedded in the concrete and as well as up to 60 mm depth, with the aid of Caesium-137(Cs) r...

Study of the Compton scattering effect of soft tissue in PET imaging by Monte Carlo method

Introduction:In PET imaging, one or both of two annihilation photons may change the direction before reaching the detector due to Compton scattering interaction in body. .Methods:This article, a Monte Carlo simulation study, examined the effect of soft tissue on this error.In this work, the PET BiographTM 6 scanner, a simple geometry of soft tissue -including a sphere of soft tissue in center ...

Simulation and patient studies of scatter correction in cardiac SPECT imaging

Introduction: Myocardial perfusion imaging is a nuclear medicine imaging method that is used to detect coronary artery diseases. One of the main sources of error in this imaging method is the detection of Compton scattered photons in the photopeak energy window used for data acquisition. This results in the degradation of the image contrast, and therefore decreases the...
