A - Radio waves are used to generate images by disrupting hydrogen nuclei in tissues 无线电波通过打乱组织中的氢原子核来产生图像
B - A detector panel converts x-rays into electrical signals; an analog image is created which is then digitalized 探测器面板将x射线转换成电信号;创建一个模拟图像，然后将其数字化
C - Technetium 99 is administered to a patient; photon emission is detected and recorded with a gamma scintillation camera 给动物使用锝99之后;用伽玛闪烁照相机探测和记录光子发射
D - An x-ray beam passes transaxially through a small segment of the patient; an image is created by measuring x-ray attenuation at sequential sites X射线束横穿动物的一小部分；通过测量连续部位的X射线衰减来生成图像
E - A transducer emits a short pulse of sound into the patient; the sound that is reflected back creates an image 传感器向动物发出短脉冲声波；反射回来的声波产生图像
