一、微波成象频率为千兆赫兹的微波辐射能透射生物体,并且如同X—射线一样透过的辐射可用于成象。含水量不同的组织显示差别很大。微波无电离作用,因此不会致癌。微波这些特点将使乳房组织的非脂肪瘤或胸腔内的肺癌检测简化。已经用微波对几例生物体做了逐点传送成象和CT扫描,很多方面的对比都优于X射线。微波空间分辨力约为1厘米。这见介绍并讨论了犬的肾和乳房组织用微波和用X—射线成象的影像。
1. Microwave radiation at a microwave imaging frequency of gigahertz can transmit organisms, and radiation transmitted as X-rays can be used for imaging. Organizations with different moisture contents show great differences. Microwaves are not ionized and therefore do not cause cancer. These characteristics of microwaves will simplify the detection of non-lipoma or intrathoracic lung cancer in breast tissue. Several instances of organisms have been microwaved to perform point-by-point imaging and CT scans, and many aspects are better than X-rays. The spatial resolution of microwaves is about 1 cm. This sees and discusses images of kidney and breast tissue in dogs using microwaves and X-ray imaging.
