1、引言生物组织和其他所有物质一样,在不同的体温下以热噪声形式辐射出不同的电磁波来。由体内数厘米深机体组织辐射出的电磁波中,微波分量边衰减边向体外传播,最后辐射到体外。这些微波能量被放置在体外的微波天线所接收,然后借助高灵敏度热噪声接收机来进行测量。若在特定的单一频率下进行测量,可以测得体表至某一深度之间的平均温度。将这种方法用于检测乳腺癌等皮下组织(2~3厘米深度以内)中高温区的尝试
1, Introduction Biological tissues, like all other substances, radiate different electromagnetic waves in the form of thermal noise at different body temperatures. By the body a few centimeters deep body tissue radiation electromagnetic waves, while the attenuation of microwave components spread to the body, the final radiation to the body. These microwave energy is received by the microwave antenna in vitro and then measured with a highly sensitive thermal noise receiver. When measured at a specific single frequency, the average temperature in the body surface to a certain depth can be measured. This method is used to detect breast cancer and other subcutaneous tissue (2 ~ 3 cm depth) try high temperature area
