摘要
利用颅脑CT图像的特点,结合医学先验知识,提出一种完全自动化的、基于颅脑CT容积数据的脑萎缩定量诊断的算法。通过2388例正常和脑萎缩病例的计算验证表明该算法有效。
In this paper, a new, fully - automatic method for the quantification of brain atrophy based on CT volume data is put forward by taking advantage of the characteristics of cerebral CT images in combination with the prior medical knowledge. This algorithm has been verified through the calculation of 2388 cases of normal and brain atrophy subjects.
