摘要

本文通过实验测量了射线自成像的点扩展函数，并将其与数字图像恢复技术相结合，提高了射线自成像的分辨率。我们比较了两种正则化迭代图像恢复算法应用于放射自成像。在恢复之前，使用非线性滤波器去除100 μ m的颗粒噪声。我们的结果表明分辨率提高了23%。

Regularized iterative image restoration algorithms applied to autoradiography

In this paper the point spread function of autoradiography is experimentally measured and used with digital image restoration techniques to improve the resolution of autoradiographs. We compare two regularized iterative image restoration algorithms applied to autoradiography. A nonlinear filter is used for the removal of f i l m grain noise prior to restoration. Our results indicate a 23% improvement in resolution.
