A high-precision rotated elliptical beam profiling method based on pixel ion chamber is proposed in this paper. This method aims to improve the accuracy by modeling the transverse profile of rotated beam as an ellipse with additional correlation coefficient and eliminating the fitting error due to the volume averaging effect of pixel ion chamber.

基于多几何参数的高斯拟合算法用于使用像素离子室的旋转椭圆光束轮廓分析

本文提出了一种基于像素离子室的高精度旋转椭圆光束轮廓分析方法。该方法旨在通过将旋转光束的横向轮廓建模为具有附加相关系数的椭圆并消除由于像素离子室的体积平均效应引起的拟合误差来提高精度。
