中文简介: | Saltzman教授继续讨论生物医学成像技术。磁共振成像(MRI)作为另一种成像形式引入,它不使用电离辐射,但可以提供身体的详细结构。功能磁共振成像(fMRI)有着不同于传统磁共振成像的应用。它可以用来测量耗氧量(组织代谢率),是解读大脑功能的重要工具。第三,超声成像是另一种成像技术,它可以通过在快速时间尺度上将声波反射转换为结构图像来检测运动。最后,讨论了核成像的例子和光学显微镜的进展。 |
课程简介: | Professor Saltzman continues his discussion of biomedical imaging technology. Magnetic resonance imaging (MRI) is introduced as an alternate form of imaging, which does not use ionizing radiation yet can provide detailed structure of the body. Functional MRI (fMRI) has a different application from traditional MRI. It can be used to measure oxygen consumption (tissue metabolic rate), and is an important tool in deciphering brain function. Third, ultrasound imaging is another imaging technique that can detect motion by translating sound wave reflections into structural images at fast timescale. Finally, examples of nuclear imaging and advances in light microscopy are discussed. |
