Abstract

In this paper, a simple procedure of exceptional geometrical form simulation is designed by using GATE (Geant4 application tomography emission) software packages. The phantom used, has an unusual geometry, which makes the acquisition of images and their reconstruction more complicated. The results obtained show that signal-to-noise ration (SNR) of sinograms and images, resolution spatial and lines profile are almost perfect.

Geant4在层析成像中的特殊幻像的蒙特卡罗模拟

摘要

在本文中，通过使用GATE（Geant4应用层析成像发射）软件包设计了一种简单的异常几何形状模拟程序。所使用的体模具有不寻常的几何形状，这使得图像的获取及其重建更加复杂。获得的结果表明，正弦图和图像的信噪比（SNR），分辨率空间和线条轮廓几乎完美。
