BRAIN IMAGING

各种临床成像方法正被用于研究大脑。 在活体内。这些技术能够比较严重的异构性 CAT-计算机轴位断层扫描；MRI-磁共振 成像)大脑的电活动(EEG- 脑电；ERPS事件相关电位)和 特定区域的葡萄糖利用率(PET-Positron 发射断层扫描)。从临床角度来看，这些 与其他诊断测试相结合的技术能够 关于解剖学和解剖学的定性判断 大脑的生理完整性。为了在数量上 分析图像数据，成像技术本身就是 被调查的，以及相关的 重建的数学模型和主观输入 大脑的图像。此外，数学和统计 评价和关联这些不同来源的方法 正在开发的多变量数据。

Various clinical imaging methods are being used to study the brain in vivo. These techniques enable comparisons of gross antomy (CAT - Computed Axial Tomography; MRI - Magnetic Resonance Imaging) of the brain with electrical activity (EEG - electroencephalography; ERPS - event-Related Potentials) and rate of glucose utilization in specific regions (PET - Positron Emission Tomography). From a clinical perspective, these techniques, in association with other diagnostic tests, enable qualitative judgments to be made as to the anatomic and physiologic integrity of the brain. In order to quantitatively analyze image data, the imaging techniques themselves are being investigated, as well as the effects of the associated mathematical models and subjective inputs on the reconstruction of the brain image. Moreover, mathematical and statistical methods for evaluating and relating these various sources of multivariate data being developed.
