The introduction of novel applications in X-ray breast imaging warrants new research for image acquisition optimisation. A simulation model was developed to investigate the influence of different imaging techniques and acquisition parameters. It was modelled in Monte Carlo N-Particle Extended and contains an X-ray tube with photon production, a breast model and antiscatter grid model. This paper describes the simulation model, compares the results with experimental and literature data and presents the influence of breast and antiscatter grid parameters on scatter radiation.
X射线乳腺成像中新型应用的引入需要开展新的研究以优化图像采集。我们开发了一个模拟模型来研究不同成像技术和采集参数的影响。该模型在蒙特卡罗N粒子扩展程序中构建,包含一个产生光子的X射线管、一个乳腺模型和一个反散射栅格模型。本文描述了该模拟模型,将结果与实验数据和文献数据进行了比较,并展示了乳腺和反散射栅格参数对散射辐射的影响。
