Currently, restoration of visual function based on nerve electrical stimulation can be divided into three types: retinal repair, optic nerve repair, and visual cortex repair. 目前基于神经电刺激的视觉功能修复主要可以分为三种:视网膜修复、视神经修复、以及视皮层修复。
Then, based on retinal cortex theory, we can estimate the effective radiation image, and apply it to EPID image enhancement, removing the low contrast brought by too strong or too low X-ray. 然后,基于视网膜皮层理论可有效的估计出照射图像,将其应用于EPID图像增强中,去处X射线过强或过弱带来的对比度过低。
