Ultra-fast diagnosis technique based on image super-resolution

  • 摘要: 时间分辨力是变像管扫描相机的重要技术参数,提出了将超分辨率图像复原理论应用于超快诊断研究,首先阐述了图像超分辨率复原在超快诊断中应用的可能性,给出了变像管扫描相机图像点扩散函数的分析和计算方法。最后,基于PoissonMMAP(MPMAP)超分辨力复原算法,获得了Au阴极X射线变像管扫描相机的图像复原结果,实验结果证明了方法的有效性,为变像管扫描相机时间分辨力的提高提供了一种新的途径。
    Abstract: Super-resolution restoration is employed with image converted tube streak camera to improve time resolution of camera. The feasibility of the image of streak camera being processed by super-resolution restoring is presented. The point spread function of streak image is described and formulated. The image restoration results of X-ray streak camera of Au photocathode are obtained with Poisson-MMAP(MPMAP)algorithm. The experimental results show that the super-resolution image restoration on ultra-fast diagnosis can be used for improving time resolution of image converted tube streak camera.
