阅读说明：本技术 脑成像 (Brain imaging ) 是由 S·查恩斯 M·詹金森 M·托瑞索 于 2019-12-09 设计创作，主要内容包括：本公开总体上涉及医学成像,并且更具体地,本公开涉及用于执行脑的磁共振(MR)成像的处理的方法和系统,所述方法和系统可以用于诊断认知障碍。更具体地,本发明包含用于处理来自受试者的脑区域的皮质扩散数据的方法,所述方法包括使用角度R值和轴向扩散率值确定轴向柱状折射(ACR)值。(The present disclosure relates generally to medical imaging, and more particularly, to methods and systems for performing a process of Magnetic Resonance (MR) imaging of the brain, which may be used to diagnose cognitive disorders. More specifically, the invention encompasses methods for processing cortical diffusion data from a brain region of a subject, the methods comprising determining Axial Columnar Refraction (ACR) values using angle R values and axial diffusivity values.)
