中文简介: | 萨尔茨曼教授首先回顾了电磁光谱、光谱的不同区域、它们各自的波长、能量以及检测它们的方法。然后,他谈到了利用高能无线电波对人体进行成像。详细介绍了X射线成像的历史、组成、优点和局限性。接下来,他介绍了计算机断层扫描(Computed Tomography),这是一种相关的成像技术,它使用数学计算将线扫描X射线编译成三维图像。最后,索尔兹曼教授谈到了X射线辐射的有害影响,以及限制或避免这些成像技术过度曝光的方法。 |
课程简介: | Professor Saltzman first reviews the electromagnetic spectrum, the different regimes of the spectrum, their respective wavelengths, energies, and ways of detecting them. He then talks about the use of high energy radio waves for imaging of the body. The history, components, advantages and limitations of X-ray imaging are presented in detail. Next, he introduces Computed Tomography, a related imaging technique which uses mathematical computation to compile line-scanned X-rays into a three dimensional image. Finally, Professor Saltzman touches on harmful effects of X-ray radiation, and ways to limit or avoid overexposure in these imaging techniques. |
