摘要
目的 :探讨增强颅脑MRI图像病变部位的信号强度的方法 ,从而为自动筛选病变区域提供依据。方法 :设计利用灰度切片的非对称非线性映射的数学方法同时对灰度 -视觉响应进行补偿。结果 :处理结果显示 ,颅脑MR图像病变部位的信号强度得到增强。结论
Objective:To probe into the methods for enhancing signal intensity of pathological changes via conduct of Brain MRI,consequently making a basis for automatic filtration for them.Methods:This method of math designed asymmetrical and nonlinear mapping by grayscale slices,which considers the effect of visual response to grayness.Results:To made a show of results,signal intensity of pathological changes via conduct of Brain MRI are boost up.Conˉclusion:This method enhancing signal intensity for area of pathological changes of Brain MRI,which are difference of slim grayscale.
