Microwave thermal radiometry for detecting cancer in deep human tissues

In order to overcome the depth limit of detectability by a microwave radiometer for cancer, the dual Archimedes spiral microstrip probe, which is highly effective in receiving the microwave thermal radiation energy, must be used. The result concerning the noninvasive microwave diagnosis of cancer in deep human tissues is given. It is concluded that the use of a S-band microwave radiometer is an effective method in the screening and early diagnosis of cancer in deep tissues. This has been proved by more than 1250 cases at eight hospitals.<>
